Introduction</H2> + +<P> +This document gives information needed for compiling and/or porting Berkeley +SoftFloat, a library of C functions implementing binary floating-point +conforming to the IEEE Standard for Floating-Point Arithmetic. +For basic documentation about SoftFloat refer to +<A HREF="SoftFloat.html"><NOBR><CODE>SoftFloat.html</CODE></NOBR></A>. +</P> + +<P> +The source code for SoftFloat is intended to be relatively machine-independent +and should be compilable with any ISO-Standard C compiler that also supports +<NOBR>64-bit</NOBR> integers. +SoftFloat has been successfully compiled with the GNU C Compiler +(<CODE>gcc</CODE>) for several platforms. +</P> + +<P> +<NOBR>Release 3</NOBR> of SoftFloat was a complete rewrite relative to +<NOBR>Release 2</NOBR> or earlier. +Changes to the interface of SoftFloat functions are documented in +<A HREF="SoftFloat.html"><NOBR><CODE>SoftFloat.html</CODE></NOBR></A>. +The current version of SoftFloat is <NOBR>Release 3e</NOBR>. +</P> + + +<H2>2. Limitations</H2> + +<P> +SoftFloat assumes the computer has an addressable byte size of either 8 or +<NOBR>16 bits</NOBR>. +(Nearly all computers in use today have <NOBR>8-bit</NOBR> bytes.) +</P> + +<P> +SoftFloat is written in C and is designed to work with other C code. +The C compiler used must conform at a minimum to the 1989 ANSI standard for the +C language (same as the 1990 ISO standard) and must in addition support basic +arithmetic on <NOBR>64-bit</NOBR> integers. +Earlier releases of SoftFloat included implementations of <NOBR>32-bit</NOBR> +single-precision and <NOBR>64-bit</NOBR> double-precision floating-point that +did not require <NOBR>64-bit</NOBR> integers, but this option is not supported +starting with <NOBR>Release 3</NOBR>. +Since 1999, ISO standards for C have mandated compiler support for +<NOBR>64-bit</NOBR> integers. +A compiler conforming to the 1999 C Standard or later is recommended but not +strictly required. +</P> + +<P> +<NOBR>C Standard</NOBR> header files <CODE><stdbool.h></CODE> and +<CODE><stdint.h></CODE> are required for defining standard Boolean and +integer types. +If these headers are not supplied with the C compiler, minimal substitutes must +be provided. +SoftFloat’s dependence on these headers is detailed later in +<NOBR>section 5.1</NOBR>, <I>Standard Headers <CODE><stdbool.h></CODE> +and <CODE><stdint.h></CODE></I>. +</P> + + +<H2>3.

SoftFloat Package Directory Structure</H2> + +<P> +Because SoftFloat is targeted to multiple platforms, its source code is +slightly scattered between target-specific and target-independent directories +and files. +The supplied directory structure is as follows: +<BLOCKQUOTE> +<PRE> +doc +source + include + 8086 + 8086-SSE + ARM-VFPv2 + ARM-VFPv2-defaultNaN +build + template-FAST_INT64 + template-not-FAST_INT64 + Linux-386-GCC + Linux-386-SSE2-GCC + Linux-x86_64-GCC + Linux-ARM-VFPv2-GCC + Win32-MinGW + Win32-SSE2-MinGW + Win64-MinGW-w64 +</PRE> +</BLOCKQUOTE> +The majority of the SoftFloat sources are provided in the <CODE>source</CODE> +directory. +The <CODE>include</CODE> subdirectory contains several header files +(unsurprisingly), while the other subdirectories of <CODE>source</CODE> contain +source files that specialize the floating-point behavior to match particular +processor families: +<BLOCKQUOTE> +<DL> +<DT><CODE>8086</CODE></DT> +<DD> +Intel’s older, 8087-derived floating-point, extended to all supported +floating-point types +</DD> +<DT><CODE>8086-SSE</CODE></DT> +<DD> +Intel’s x86 processors with Streaming SIMD Extensions (SSE) and later +compatible extensions, having 8087 behavior for <NOBR>80-bit</NOBR> +double-extended-precision (<CODE>extFloat80_t</CODE>) and SSE behavior for +other floating-point types +</DD> +<DT><CODE>ARM-VFPv2</CODE></DT> +<DD> +ARM’s VFPv2 or later floating-point, with NaN payload propagation +</DD> +<DT><CODE>ARM-VFPv2-defaultNaN</CODE></DT> +<DD> +ARM’s VFPv2 or later floating-point, with the “default NaN” +option +</DD> +</DL> +</BLOCKQUOTE> +If other specializations are attempted, these would be expected to be other +subdirectories of <CODE>source</CODE> alongside the ones listed above. +Specialization is covered later, in <NOBR>section 5.2</NOBR>, <I>Specializing +Floating-Point Behavior</I>. +</P> + +<P> +The <CODE>build</CODE> directory is intended to contain a subdirectory for each +target platform for which a build of the SoftFloat library may be created. +For each build target, the target’s subdirectory is where all derived +object files and the completed SoftFloat library (typically +<CODE>softfloat.a</CODE> or <CODE>libsoftfloat.a</CODE>) are created. +The two <CODE>template</CODE> subdirectories are not actual build targets but +contain sample files for creating new target directories. +(The meaning of <CODE>FAST_INT64</CODE> will be explained later.) +</P> + +<P> +Ignoring the <CODE>template</CODE> directories, the supplied target directories +are intended to follow a naming system of +<NOBR><CODE><<I>execution-environment</I>>-<<I>compiler</I>></CODE></NOBR>. +For the example targets, +<NOBR><CODE><<I>execution-environment</I>></CODE></NOBR> is +<NOBR><CODE>Linux-386</CODE></NOBR>, <NOBR><CODE>Linux-386-SSE2</CODE></NOBR>, +<NOBR><CODE>Linux-x86_64</CODE></NOBR>, +<NOBR><CODE>Linux-ARM-VFPv2</CODE></NOBR>, <CODE>Win32</CODE>, +<NOBR><CODE>Win32-SSE2</CODE></NOBR>, or <CODE>Win64</CODE>, and +<NOBR><CODE><<I>compiler</I>></CODE></NOBR> is <CODE>GCC</CODE>, +<CODE>MinGW</CODE>, or <NOBR><CODE>MinGW-w64</CODE></NOBR>. +</P> + +<P> +All of the supplied target directories are merely examples that may or may not +be correct for compiling on any particular system. +Despite requests, there are currently no plans to include and maintain in the +SoftFloat package the build files needed for a great many users’ +compilation environments, which can span a huge range of operating systems, +compilers, and other tools. +</P> + +<P> +As supplied, each target directory contains two files: +<BLOCKQUOTE> +<PRE> +Makefile +platform.h +</PRE> +</BLOCKQUOTE> +The provided <CODE>Makefile</CODE> is written for GNU <CODE>make</CODE>. +A build of SoftFloat for the specific target is begun by executing the +<CODE>make</CODE> command with the target directory as the current directory. +A completely different build tool can be used if an appropriate +<CODE>Makefile</CODE> equivalent is created. +</P> + +<P> +The <CODE>platform.h</CODE> header file exists to provide a location for +additional C declarations specific to the build target. +Every C source file of SoftFloat contains a <CODE>#include</CODE> for +<CODE>platform.h</CODE>. +In many cases, the contents of <CODE>platform.h</CODE> can be as simple as one +or two lines of code. +At the other extreme, to get maximal performance from SoftFloat, it may be +desirable to include in header <CODE>platform.h</CODE> (directly or via +<CODE>#include</CODE>) declarations for numerous target-specific optimizations. +Such possibilities are discussed in the next section, <I>Issues for Porting +SoftFloat to a New Target</I>. +If the target’s compiler or library has bugs or other shortcomings, +workarounds for these issues may also be possible with target-specific +declarations in <CODE>platform.h</CODE>, avoiding the need to modify the main +SoftFloat sources. +</P> + + +<H2>5. Issues for Porting SoftFloat to a New Target</H2> + +<H3>5.1. Standard Headers <CODE><stdbool.h></CODE> and <CODE><stdint.h></CODE></H3> + +<P> +The SoftFloat sources make use of standard headers +<CODE><stdbool.h></CODE> and <CODE><stdint.h></CODE>, which have +been part of the ISO C Standard Library since 1999. +With any recent compiler, these standard headers are likely to be supported, +even if the compiler does not claim complete conformance to the latest ISO C +Standard. +For older or nonstandard compilers, substitutes for +<CODE><stdbool.h></CODE> and <CODE><stdint.h></CODE> may need to be +created. +SoftFloat depends on these names from <CODE><stdbool.h></CODE>: +<BLOCKQUOTE> +<PRE> +bool +true +false +</PRE> +</BLOCKQUOTE> +and on these names from <CODE><stdint.h></CODE>: +<BLOCKQUOTE> +<PRE> +uint16_t +uint32_t +uint64_t +int32_t +int64_t +UINT64_C +INT64_C +uint_least8_t +uint_fast8_t +uint_fast16_t +uint_fast32_t +uint_fast64_t +int_fast8_t +int_fast16_t +int_fast32_t +int_fast64_t +</PRE> +</BLOCKQUOTE> +</P> + + +<H3>5.2. Specializing Floating-Point Behavior</H3> + +<P> +The IEEE Floating-Point Standard allows for some flexibility in a conforming +implementation, particularly concerning NaNs. +The SoftFloat <CODE>source</CODE> directory is supplied with some +<I>specialization</I> subdirectories containing possible definitions for this +implementation-specific behavior. +For example, the <CODE>8086</CODE> and <NOBR><CODE>8086-SSE</CODE></NOBR> +subdirectories have source files that specialize SoftFloat’s behavior to +match that of Intel’s x86 line of processors. +The files in a specialization subdirectory must determine: +<UL> +<LI> +whether tininess for underflow is detected before or after rounding by default; +<LI> +how signaling NaNs are distinguished from quiet NaNs; +<LI> +what (if anything) special happens when exceptions are raised; +<LI> +the default generated quiet NaNs; +<LI> +how NaNs are propagated from function inputs to output; and +<LI> +the integer results returned when conversions to integer type raise the +<I>invalid</I> exception. +</UL> +</P> + +<P> +As provided, the build process for a target expects to involve exactly +<EM>one</EM> specialization directory that defines <EM>all</EM> of these +implementation-specific details for the target. +A specialization directory such as <CODE>8086</CODE> is expected to contain a +header file called <CODE>specialize.h</CODE>, together with whatever other +source files are needed to complete the specialization. +</P> + +<P> +A new build target may use an existing specialization, such as the ones +provided by the <CODE>8086</CODE> and <NOBR><CODE>8086-SSE</CODE></NOBR> +subdirectories. +If a build target needs a new specialization, different from any existing ones, +it is recommended that a new specialization directory be created for this +purpose. +The <CODE>specialize.h</CODE> header file from any of the provided +specialization subdirectories can be used as a model for what definitions are +needed. +</P> + + +<H3>5.3. Macros for Build Options</H3> + +<P> +The SoftFloat source files adapt the floating-point implementation according to +several C preprocessor macros: +<BLOCKQUOTE> +<DL> +<DT><CODE>LITTLEENDIAN</CODE> +<DD> +Must be defined for little-endian machines; must not be defined for big-endian +machines. +<DT><CODE>INLINE</CODE> +<DD> +Specifies the sequence of tokens used to indicate that a C function should be +inlined. +If macro <CODE>INLINE_LEVEL</CODE> is defined with a value of 1 or higher, this +macro must be defined; otherwise, this macro is ignored and need not be +defined. +For compilers that conform to the C Standard’s rules for inline +functions, this macro can be defined as the single keyword <CODE>inline</CODE>. +For other compilers that follow a convention pre-dating the standardization of +<CODE>inline</CODE>, this macro may need to be defined to <CODE>extern</CODE> +<CODE>inline</CODE>. +<DT><CODE>THREAD_LOCAL</CODE> +<DD> +Can be defined to a sequence of tokens that, when appearing at the start of a +variable declaration, indicates to the C compiler that the variable is +<I>per-thread</I>, meaning that each execution thread gets its own separate +instance of the variable. +This macro is used in header <CODE>softfloat.h</CODE> in the declarations of +variables <CODE>softfloat_roundingMode</CODE>, +<CODE>softfloat_detectTininess</CODE>, <CODE>extF80_roundingPrecision</CODE>, +and <CODE>softfloat_exceptionFlags</CODE>. +If macro <CODE>THREAD_LOCAL</CODE> is left undefined, these variables will +default to being ordinary global variables. +Depending on the compiler, possible valid definitions of this macro include +<CODE>_Thread_local</CODE> and <CODE>__thread</CODE>. +</DL> +<DL> +<DT><CODE>SOFTFLOAT_ROUND_ODD</CODE> +<DD> +Can be defined to enable support for optional rounding mode +<CODE>softfloat_round_odd</CODE>. +</DL> +<DL> +<DT><CODE>INLINE_LEVEL</CODE> +<DD> +Can be defined to an integer to determine the degree of inlining requested of +the compiler. +Larger numbers request that more inlining be done. +If this macro is not defined or is defined to a value less <NOBR>than 1</NOBR> +(zero or negative), no inlining is requested. +The maximum effective value is no higher <NOBR>than 5</NOBR>. +Defining this macro to a value greater than 5 is the same as defining it +<NOBR>to 5</NOBR>. +<DT><CODE>SOFTFLOAT_FAST_INT64</CODE> +<DD> +Can be defined to indicate that the build target’s implementation of +<NOBR>64-bit</NOBR> arithmetic is efficient. +For newer <NOBR>64-bit</NOBR> processors, this macro should usually be defined. +For very small microprocessors whose buses and registers are <NOBR>8-bit</NOBR> +or <NOBR>16-bit</NOBR> in size, this macro should usually not be defined. +Whether this macro should be defined for a <NOBR>32-bit</NOBR> processor may +depend on the target machine and the applications that will use SoftFloat. +<DT><CODE>SOFTFLOAT_FAST_DIV32TO16</CODE> +<DD> +Can be defined to indicate that the target’s division operator +<NOBR>in C</NOBR> (written as <CODE>/</CODE>) is reasonably efficient for +dividing a <NOBR>32-bit</NOBR> unsigned integer by a <NOBR>16-bit</NOBR> +unsigned integer. +Setting this macro may affect the performance of function <CODE>f16_div</CODE>. +<DT><CODE>SOFTFLOAT_FAST_DIV64TO32</CODE> +<DD> +Can be defined to indicate that the target’s division operator +<NOBR>in C</NOBR> (written as <CODE>/</CODE>) is reasonably efficient for +dividing a <NOBR>64-bit</NOBR> unsigned integer by a <NOBR>32-bit</NOBR> +unsigned integer. +Setting this macro may affect the performance of division, remainder, and +square root operations other than <CODE>f16_div</CODE>. +</DL> +</BLOCKQUOTE> +</P> + +<P> +Following the usual custom <NOBR>for C</NOBR>, for most of these macros (all +except <CODE>INLINE</CODE>, <CODE>THREAD_LOCAL</CODE>, and +<CODE>INLINE_LEVEL</CODE>), the content of any definition is irrelevant; +what matters is a macro’s effect on <CODE>#ifdef</CODE> directives. +</P> + +<P> +It is recommended that any definitions of macros <CODE>LITTLEENDIAN</CODE>, +<CODE>INLINE</CODE>, and <CODE>THREAD_LOCAL</CODE> be made in a build +target’s <CODE>platform.h</CODE> header file, because these macros are +expected to be determined inflexibly by the target machine and compiler. +The other five macros select options and control optimization, and thus might +be better located in the target’s Makefile (or its equivalent). +</P> + + +<H3>5.4. Adapting a Template Target Directory</H3> + +<P> +In the <CODE>build</CODE> directory, two <CODE>template</CODE> subdirectories +provide models for new target directories. +Two different templates exist because different functions are needed in the +SoftFloat library depending on whether macro <CODE>SOFTFLOAT_FAST_INT64</CODE> +is defined. +If macro <CODE>SOFTFLOAT_FAST_INT64</CODE> will be defined, +<NOBR><CODE>template-FAST_INT64</CODE></NOBR> is the template to use; +otherwise, <NOBR><CODE>template-not-FAST_INT64</CODE></NOBR> is the appropriate +template. +A new target directory can be created by copying the correct template directory +and editing the files inside. +To avoid confusion, it would be wise to refrain from editing the files within a +template directory directly. +</P> + + +<H3>5.5. Target-Specific Optimization of Primitive Functions</H3> + +<P> +Header file <CODE>primitives.h</CODE> (in directory +<CODE>source/include</CODE>) declares macros and functions for numerous +underlying arithmetic operations upon which many of SoftFloat’s +floating-point functions are ultimately built. +The SoftFloat sources include implementations of all of these functions/macros, +written as standard C code, so a complete and correct SoftFloat library can be +created using only the supplied code for all functions. +However, for many targets, SoftFloat’s performance can be improved by +substituting target-specific implementations of some of the functions/macros +declared in <CODE>primitives.h</CODE>. +</P> + +<P> +For example, <CODE>primitives.h</CODE> declares a function called +<CODE>softfloat_countLeadingZeros32</CODE> that takes an unsigned +<NOBR>32-bit</NOBR> integer as an argument and returns the number of the +integer’s most-significant bits that are zeros. +While the SoftFloat sources include an implementation of this function written +in <NOBR>standard C</NOBR>, many processors can perform this same function +directly in only one or two machine instructions. +An alternative, target-specific implementation that maps to those instructions +is likely to be more efficient than the generic C code from the SoftFloat +package. +</P> + +<P> +A build target can replace the supplied version of any function or macro of +<CODE>primitives.h</CODE> by defining a macro with the same name in the +target’s <CODE>platform.h</CODE> header file. +For this purpose, it may be helpful for <CODE>platform.h</CODE> to +<CODE>#include</CODE> header file <CODE>primitiveTypes.h</CODE>, which defines +types used for arguments and results of functions declared in +<CODE>primitives.h</CODE>. +When a desired replacement implementation is a function, not a macro, it is +sufficient for <CODE>platform.h</CODE> to include the line +<BLOCKQUOTE> +<PRE> +#define <<I>function-name</I>> <<I>function-name</I>> +</PRE> +</BLOCKQUOTE> +where <NOBR><CODE><<I>function-name</I>></CODE></NOBR> is the name of the +function. +This technically defines <NOBR><CODE><<I>function-name</I>></CODE></NOBR> +as a macro, but one that resolves to the same name, which may then be a +function. +(A preprocessor that conforms to the C Standard is required to limit recursive +macro expansion from being applied more than once.) +</P> + +<P> +The supplied header file <CODE>opts-GCC.h</CODE> (in directory +<CODE>source/include</CODE>) provides an example of target-specific +optimization for the GCC compiler. +Each GCC target example in the <CODE>build</CODE> directory has +<BLOCKQUOTE> +<CODE>#include "opts-GCC.h"</CODE> +</BLOCKQUOTE> +in its <CODE>platform.h</CODE> header file. +Before <CODE>opts-GCC.h</CODE> is included, the following macros must be +defined (or not) to control which features are invoked: +<BLOCKQUOTE> +<DL> +<DT><CODE>SOFTFLOAT_BUILTIN_CLZ</CODE></DT> +<DD> +If defined, SoftFloat’s internal +‘<CODE>countLeadingZeros</CODE>’ functions use intrinsics +<CODE>__builtin_clz</CODE> and <CODE>__builtin_clzll</CODE>. +</DD> +<DT><CODE>SOFTFLOAT_INTRINSIC_INT128</CODE></DT> +<DD> +If defined, SoftFloat makes use of GCC’s nonstandard <NOBR>128-bit</NOBR> +integer type <CODE>__int128</CODE>. +</DD> +</DL> +</BLOCKQUOTE> +On some machines, these improvements are observed to increase the speeds of +<CODE>f64_mul</CODE> and <CODE>f128_mul</CODE> by around 20 to 25%, although +other functions receive less dramatic boosts, or none at all. +Results can vary greatly across different platforms. +</P> + + +<H2>6. Testing SoftFloat</H2> + +<P> +SoftFloat can be tested using the <CODE>testsoftfloat</CODE> program by the +same author. +This program is part of the Berkeley TestFloat package available at the Web +page +<A HREF="http://www.jhauser.us/arithmetic/TestFloat.html"><NOBR><CODE>http://www.jhauser.us/arithmetic/TestFloat.html</CODE></NOBR></A>. +The TestFloat package also has a program called <CODE>timesoftfloat</CODE> that +measures the speed of SoftFloat’s floating-point functions. +</P> + + +<H2>7. Providing SoftFloat as a Common Library for Applications</H2> + +<P> +Header file <CODE>softfloat.h</CODE> defines the SoftFloat interface as seen by +clients. +If the SoftFloat library will be made a common library for programs on a +system, the supplied <CODE>softfloat.h</CODE> has a couple of deficiencies for +this purpose: +<UL> +<LI> +As supplied, <CODE>softfloat.h</CODE> depends on another header, +<CODE>softfloat_types.h</CODE>, that is not intended for public use but which +must also be visible to the programmer’s compiler. +<LI> +More troubling, at the time <CODE>softfloat.h</CODE> is included in a C source +file, macros <CODE>SOFTFLOAT_FAST_INT64</CODE> and <CODE>THREAD_LOCAL</CODE> +must be defined, or not defined, consistent with how these macro were defined +when the SoftFloat library was built. +</UL> +In the situation that new programs may regularly <CODE>#include</CODE> header +file <CODE>softfloat.h</CODE>, it is recommended that a custom, self-contained +version of this header file be created that eliminates these issues. +</P> + + +<H2>8.

Introduction</H2> + +<P> +Berkeley SoftFloat is a software implementation of binary floating-point that +conforms to the IEEE Standard for Floating-Point Arithmetic. +The current release supports five binary formats: <NOBR>16-bit</NOBR> +half-precision, <NOBR>32-bit</NOBR> single-precision, <NOBR>64-bit</NOBR> +double-precision, <NOBR>80-bit</NOBR> double-extended-precision, and +<NOBR>128-bit</NOBR> quadruple-precision. +The following functions are supported for each format: +<UL> +<LI> +addition, subtraction, multiplication, division, and square root; +<LI> +fused multiply-add as defined by the IEEE Standard, except for +<NOBR>80-bit</NOBR> double-extended-precision; +<LI> +remainder as defined by the IEEE Standard; +<LI> +round to integral value; +<LI> +comparisons; +<LI> +conversions to/from other supported formats; and +<LI> +conversions to/from <NOBR>32-bit</NOBR> and <NOBR>64-bit</NOBR> integers, +signed and unsigned. +</UL> +All operations required by the original 1985 version of the IEEE Floating-Point +Standard are implemented, except for conversions to and from decimal. +</P> + +<P> +This document gives information about the types defined and the routines +implemented by SoftFloat. +It does not attempt to define or explain the IEEE Floating-Point Standard. +Information about the standard is available elsewhere. +</P> + +<P> +The current version of SoftFloat is <NOBR>Release 3e</NOBR>. +This release modifies the behavior of the rarely used <I>odd</I> rounding mode +(<I>round to odd</I>, also known as <I>jamming</I>), and also adds some new +specialization and optimization examples for those compiling SoftFloat. +</P> + +<P> +The previous <NOBR>Release 3d</NOBR> fixed bugs that were found in the square +root functions for the <NOBR>64-bit</NOBR>, <NOBR>80-bit</NOBR>, and +<NOBR>128-bit</NOBR> floating-point formats. +(Thanks to Alexei Sibidanov at the University of Victoria for reporting an +incorrect result.) +The bugs affected all prior <NOBR>Release-3</NOBR> versions of SoftFloat +<NOBR>through 3c</NOBR>. +The flaw in the <NOBR>64-bit</NOBR> floating-point square root function was of +very minor impact, causing a <NOBR>1-ulp</NOBR> error (<NOBR>1 unit</NOBR> in +the last place) a few times out of a billion. +The bugs in the <NOBR>80-bit</NOBR> and <NOBR>128-bit</NOBR> square root +functions were more serious. +Although incorrect results again occurred only a few times out of a billion, +when they did occur a large portion of the less-significant bits could be +wrong. +</P> + +<P> +Among earlier releases, 3b was notable for adding support for the +<NOBR>16-bit</NOBR> half-precision format. +For more about the evolution of SoftFloat releases, see +<A HREF="SoftFloat-history.html"><NOBR><CODE>SoftFloat-history.html</CODE></NOBR></A>. +</P> + +<P> +The functional interface of SoftFloat <NOBR>Release 3</NOBR> and later differs +in many details from the releases that came before. +For specifics of these differences, see <NOBR>section 9</NOBR> below, +<I>Changes from SoftFloat <NOBR>Release 2</NOBR></I>. +</P> + + +<H2>2. Limitations</H2> + +<P> +SoftFloat assumes the computer has an addressable byte size of 8 or +<NOBR>16 bits</NOBR>. +(Nearly all computers in use today have <NOBR>8-bit</NOBR> bytes.) +</P> + +<P> +SoftFloat is written in C and is designed to work with other C code. +The C compiler used must conform at a minimum to the 1989 ANSI standard for the +C language (same as the 1990 ISO standard) and must in addition support basic +arithmetic on <NOBR>64-bit</NOBR> integers. +Earlier releases of SoftFloat included implementations of <NOBR>32-bit</NOBR> +single-precision and <NOBR>64-bit</NOBR> double-precision floating-point that +did not require <NOBR>64-bit</NOBR> integers, but this option is not supported +starting with <NOBR>Release 3</NOBR>. +Since 1999, ISO standards for C have mandated compiler support for +<NOBR>64-bit</NOBR> integers. +A compiler conforming to the 1999 C Standard or later is recommended but not +strictly required. +</P> + +<P> +Most operations not required by the original 1985 version of the IEEE +Floating-Point Standard but added in the 2008 version are not yet supported in +SoftFloat <NOBR>Release 3e</NOBR>. +</P> + + +<H2>3.

Supported Floating-Point Functions</H3> + +<P> +SoftFloat implements these arithmetic operations for its floating-point types: +<UL> +<LI> +conversions between any two floating-point formats; +<LI> +for each floating-point format, conversions to and from signed and unsigned +<NOBR>32-bit</NOBR> and <NOBR>64-bit</NOBR> integers; +<LI> +for each format, the usual addition, subtraction, multiplication, division, and +square root operations; +<LI> +for each format except <CODE>extFloat80_t</CODE>, the fused multiply-add +operation defined by the IEEE Standard; +<LI> +for each format, the floating-point remainder operation defined by the IEEE +Standard; +<LI> +for each format, a “round to integer” operation that rounds to the +nearest integer value in the same format; and +<LI> +comparisons between two values in the same floating-point format. +</UL> +</P> + +<P> +The following operations required by the 2008 IEEE Floating-Point Standard are +not supported in SoftFloat <NOBR>Release 3e</NOBR>: +<UL> +<LI> +<B>nextUp</B>, <B>nextDown</B>, <B>minNum</B>, <B>maxNum</B>, <B>minNumMag</B>, +<B>maxNumMag</B>, <B>scaleB</B>, and <B>logB</B>; +<LI> +conversions between floating-point formats and decimal or hexadecimal character +sequences; +<LI> +all “quiet-computation” operations (<B>copy</B>, <B>negate</B>, +<B>abs</B>, and <B>copySign</B>, which all involve only simple copying and/or +manipulation of the floating-point sign bit); and +<LI> +all “non-computational” operations other than <B>isSignaling</B> +(which is supported). +</UL> +</P> + +<H3>4.4. Non-canonical Representations in <CODE>extFloat80_t</CODE></H3> + +<P> +Because the <NOBR>80-bit</NOBR> double-extended-precision format, +<CODE>extFloat80_t</CODE>, stores an explicit leading significand bit, many +finite floating-point numbers are encodable in this type in multiple equivalent +forms. +Of these multiple encodings, there is always a unique one with the least +encoded exponent value, and this encoding is considered the <I>canonical</I> +representation of the floating-point number. +Any other equivalent representations (having a higher encoded exponent value) +are <I>non-canonical</I>. +For a value in the subnormal range (including zero), the canonical +representation always has an encoded exponent of zero and a leading significand +bit <NOBR>of 0</NOBR>. +For finite values outside the subnormal range, the canonical representation +always has an encoded exponent that is nonzero and a leading significand bit +<NOBR>of 1</NOBR>. +</P> + +<P> +For an infinity or NaN, the leading significand bit is similarly expected to +<NOBR>be 1</NOBR>. +An infinity or NaN with a leading significand bit <NOBR>of 0</NOBR> is again +considered non-canonical. +Hence, altogether, to be canonical, a value of type <CODE>extFloat80_t</CODE> +must have a leading significand bit <NOBR>of 1</NOBR>, unless the value is +subnormal or zero, in which case the leading significand bit and the encoded +exponent must both be zero. +</P> + +<P> +SoftFloat’s functions are not guaranteed to operate as expected when +inputs of type <CODE>extFloat80_t</CODE> are non-canonical. +Assuming all of a function’s <CODE>extFloat80_t</CODE> inputs (if any) +are canonical, function outputs of type <CODE>extFloat80_t</CODE> will always +be canonical. +</P> + +<H3>4.5. Conventions for Passing Arguments and Results</H3> + +<P> +Values that are at most <NOBR>64 bits</NOBR> in size (i.e., not the +<NOBR>80-bit</NOBR> or <NOBR>128-bit</NOBR> floating-point formats) are in all +cases passed as function arguments by value. +Likewise, when an output of a function is no more than <NOBR>64 bits</NOBR>, it +is always returned directly as the function result. +Thus, for example, the SoftFloat function for adding two <NOBR>64-bit</NOBR> +floating-point values has this simple signature: +<BLOCKQUOTE> +<CODE>float64_t f64_add( float64_t, float64_t );</CODE> +</BLOCKQUOTE> +</P> + +<P> +The story is more complex when function inputs and outputs are +<NOBR>80-bit</NOBR> and <NOBR>128-bit</NOBR> floating-point. +For these types, SoftFloat always provides a function that passes these larger +values into or out of the function indirectly, via pointers. +For example, for adding two <NOBR>128-bit</NOBR> floating-point values, +SoftFloat supplies this function: +<BLOCKQUOTE> +<CODE>void f128M_add( const float128_t *, const float128_t *, float128_t * );</CODE> +</BLOCKQUOTE> +The first two arguments point to the values to be added, and the last argument +points to the location where the sum will be stored. +The <CODE>M</CODE> in the name <CODE>f128M_add</CODE> is mnemonic for the fact +that the <NOBR>128-bit</NOBR> inputs and outputs are “in memory”, +pointed to by pointer arguments. +</P> + +<P> +All ports of SoftFloat implement these <I>pass-by-pointer</I> functions for +types <CODE>extFloat80_t</CODE> and <CODE>float128_t</CODE>. +At the same time, SoftFloat ports may also implement alternate versions of +these same functions that pass <CODE>extFloat80_t</CODE> and +<CODE>float128_t</CODE> by value, like the smaller formats. +Thus, besides the function with name <CODE>f128M_add</CODE> shown above, a +SoftFloat port may also supply an equivalent function with this signature: +<BLOCKQUOTE> +<CODE>float128_t f128_add( float128_t, float128_t );</CODE> +</BLOCKQUOTE> +</P> + +<P> +As a general rule, on computers where the machine word size is +<NOBR>32 bits</NOBR> or smaller, only the pass-by-pointer versions of functions +(e.g., <CODE>f128M_add</CODE>) are provided for types <CODE>extFloat80_t</CODE> +and <CODE>float128_t</CODE>, because passing such large types directly can have +significant extra cost. +On computers where the word size is <NOBR>64 bits</NOBR> or larger, both +function versions (<CODE>f128M_add</CODE> and <CODE>f128_add</CODE>) are +provided, because the cost of passing by value is then more reasonable. +Applications that must be portable accross both classes of computers must use +the pointer-based functions, as these are always implemented. +However, if it is known that SoftFloat includes the by-value functions for all +platforms of interest, programmers can use whichever version they prefer. +</P> + + +<H2>5. Reserved Names</H2> + +<P> +In addition to the variables and functions documented here, SoftFloat defines +some symbol names for its own private use. +These private names always begin with the prefix +‘<CODE>softfloat_</CODE>’. +When a program includes header <CODE>softfloat.h</CODE> or links with the +SoftFloat library, all names with prefix ‘<CODE>softfloat_</CODE>’ +are reserved for possible use by SoftFloat. +Applications that use SoftFloat should not define their own names with this +prefix, and should reference only such names as are documented. +</P> + + +<H2>6. Mode Variables</H2> + +<P> +The following global variables control rounding mode, underflow detection, and +the <NOBR>80-bit</NOBR> extended format’s rounding precision: +<BLOCKQUOTE> +<CODE>softfloat_roundingMode</CODE><BR> +<CODE>softfloat_detectTininess</CODE><BR> +<CODE>extF80_roundingPrecision</CODE> +</BLOCKQUOTE> +These mode variables are covered in the next several subsections. +For some SoftFloat ports, these variables may be <I>per-thread</I> (declared +<CODE>thread_local</CODE>), meaning that different execution threads have their +own separate copies of the variables. +</P> + +<H3>6.1. Rounding Mode</H3> + +<P> +All five rounding modes defined by the 2008 IEEE Floating-Point Standard are +implemented for all operations that require rounding. +Some ports of SoftFloat may also implement the <I>round-to-odd</I> mode. +</P> + +<P> +The rounding mode is selected by the global variable +<BLOCKQUOTE> +<CODE>uint_fast8_t softfloat_roundingMode;</CODE> +</BLOCKQUOTE> +This variable may be set to one of the values +<BLOCKQUOTE> +<TABLE CELLSPACING=0 CELLPADDING=0> +<TR> +<TD><CODE>softfloat_round_near_even</CODE></TD> +<TD>round to nearest, with ties to even</TD> +</TR> +<TR> +<TD><CODE>softfloat_round_near_maxMag </CODE></TD> +<TD>round to nearest, with ties to maximum magnitude (away from zero)</TD> +</TR> +<TR> +<TD><CODE>softfloat_round_minMag</CODE></TD> +<TD>round to minimum magnitude (toward zero)</TD> +</TR> +<TR> +<TD><CODE>softfloat_round_min</CODE></TD> +<TD>round to minimum (down)</TD> +</TR> +<TR> +<TD><CODE>softfloat_round_max</CODE></TD> +<TD>round to maximum (up)</TD> +</TR> +<TR> +<TD><CODE>softfloat_round_odd</CODE></TD> +<TD>round to odd (jamming), if supported by the SoftFloat port</TD> +</TR> +</TABLE> +</BLOCKQUOTE> +Variable <CODE>softfloat_roundingMode</CODE> is initialized to +<CODE>softfloat_round_near_even</CODE>. +</P> + +<P> +When <CODE>softfloat_round_odd</CODE> is the rounding mode for a function that +rounds to an integer value (either conversion to an integer format or a +‘<CODE>roundToInt</CODE>’ function), if the input is not already an +integer, the rounded result is the closest <EM>odd</EM> integer. +For other operations, this rounding mode acts as though the floating-point +result is first rounded to minimum magnitude, the same as +<CODE>softfloat_round_minMag</CODE>, and then, if the result is inexact, the +least-significant bit of the result is set <NOBR>to 1</NOBR>. +Rounding to odd is also known as <EM>jamming</EM>. +</P> + +<H3>6.2. Underflow Detection</H3> + +<P> +In the terminology of the IEEE Standard, SoftFloat can detect tininess for +underflow either before or after rounding. +The choice is made by the global variable +<BLOCKQUOTE> +<CODE>uint_fast8_t softfloat_detectTininess;</CODE> +</BLOCKQUOTE> +which can be set to either +<BLOCKQUOTE> +<CODE>softfloat_tininess_beforeRounding</CODE><BR> +<CODE>softfloat_tininess_afterRounding</CODE> +</BLOCKQUOTE> +Detecting tininess after rounding is usually better because it results in fewer +spurious underflow signals. +The other option is provided for compatibility with some systems. +Like most systems (and as required by the newer 2008 IEEE Standard), SoftFloat +always detects loss of accuracy for underflow as an inexact result. +</P> + +<H3>6.3. Rounding Precision for the <NOBR>80-Bit</NOBR> Extended Format</H3> + +<P> +For <CODE>extFloat80_t</CODE> only, the rounding precision of the basic +arithmetic operations is controlled by the global variable +<BLOCKQUOTE> +<CODE>uint_fast8_t extF80_roundingPrecision;</CODE> +</BLOCKQUOTE> +The operations affected are: +<BLOCKQUOTE> +<CODE>extF80_add</CODE><BR> +<CODE>extF80_sub</CODE><BR> +<CODE>extF80_mul</CODE><BR> +<CODE>extF80_div</CODE><BR> +<CODE>extF80_sqrt</CODE> +</BLOCKQUOTE> +When <CODE>extF80_roundingPrecision</CODE> is set to its default value of 80, +these operations are rounded to the full precision of the <NOBR>80-bit</NOBR> +double-extended-precision format, like occurs for other formats. +Setting <CODE>extF80_roundingPrecision</CODE> to 32 or to 64 causes the +operations listed to be rounded to <NOBR>32-bit</NOBR> precision (equivalent to +<CODE>float32_t</CODE>) or to <NOBR>64-bit</NOBR> precision (equivalent to +<CODE>float64_t</CODE>), respectively. +When rounding to reduced precision, additional bits in the result significand +beyond the rounding point are set to zero. +The consequences of setting <CODE>extF80_roundingPrecision</CODE> to a value +other than 32, 64, or 80 is not specified. +Operations other than the ones listed above are not affected by +<CODE>extF80_roundingPrecision</CODE>. +</P> + + +<H2>7.

Changes to Function Arguments</H3> + +<P> +Besides simple name changes, some operations were given a different interface +in <NOBR>Release 3</NOBR> than they had in <NOBR>Release 2</NOBR>: +<UL> + +<LI> +<P> +Since <NOBR>Release 3</NOBR>, integer arguments and results of functions have +standard types from header <CODE><stdint.h></CODE>, such as +<CODE>uint32_t</CODE>, whereas previously their types could be defined +differently for each port of SoftFloat, usually using traditional C types such +as <CODE>unsigned</CODE> <CODE>int</CODE>. +Likewise, functions in <NOBR>Release 3</NOBR> and later pass Booleans as +standard type <CODE>bool</CODE> from <CODE><stdbool.h></CODE>, whereas +previously these were again passed as a port-specific type (usually +<CODE>int</CODE>). +</P> + +<LI> +<P> +As explained earlier in <NOBR>section 4.5</NOBR>, <I>Conventions for Passing +Arguments and Results</I>, SoftFloat functions in <NOBR>Release 3</NOBR> and +later may pass <NOBR>80-bit</NOBR> and <NOBR>128-bit</NOBR> floating-point +values through pointers, meaning that functions take pointer arguments and then +read or write floating-point values at the locations indicated by the pointers. +In <NOBR>Release 2</NOBR>, floating-point arguments and results were always +passed by value, regardless of their size. +</P> + +<LI> +<P> +Functions that round to an integer have additional +<CODE><I>roundingMode</I></CODE> and <CODE><I>exact</I></CODE> arguments that +they did not have in <NOBR>Release 2</NOBR>. +Refer to sections 8.2 <NOBR>and 8.7</NOBR> for descriptions of these functions +since <NOBR>Release 3</NOBR>. +For <NOBR>Release 2</NOBR>, the rounding mode, when needed, was taken from the +same global variable that affects the basic arithmetic operations (now called +<CODE>softfloat_roundingMode</CODE> but previously known as +<CODE>float_rounding_mode</CODE>). +Also, for <NOBR>Release 2</NOBR>, if the original floating-point input was not +an exact integer value, and if the <I>invalid</I> exception was not raised by +the function, the <I>inexact</I> exception was always raised. +<NOBR>Release 2</NOBR> had no option to suppress raising <I>inexact</I> in this +case. +Applications using SoftFloat <NOBR>Release 3</NOBR> or later can get the same +effect as <NOBR>Release 2</NOBR> by passing variable +<CODE>softfloat_roundingMode</CODE> for argument +<CODE><I>roundingMode</I></CODE> and <CODE>true</CODE> for argument +<CODE><I>exact</I></CODE>. +</P> + +</UL> +</P> + +<H3>9.3. Added Capabilities</H3> + +<P> +With <NOBR>Release 3</NOBR>, some new features have been added that were not +present in <NOBR>Release 2</NOBR>: +<UL> + +<LI> +<P> +A port of SoftFloat can now define any of the floating-point types +<CODE>float32_t</CODE>, <CODE>float64_t</CODE>, <CODE>extFloat80_t</CODE>, and +<CODE>float128_t</CODE> as aliases for C’s standard floating-point types +<CODE>float</CODE>, <CODE>double</CODE>, and <CODE>long</CODE> +<CODE>double</CODE>, using either <CODE>#define</CODE> or <CODE>typedef</CODE>. +This potential convenience was not supported under <NOBR>Release 2</NOBR>. +</P> + +<P> +(Note, however, that there may be a performance cost to defining +SoftFloat’s floating-point types this way, depending on the platform and +the applications using SoftFloat. +Ports of SoftFloat may choose to forgo the convenience in favor of better +speed.) +</P> + +<P> +<LI> +As of <NOBR>Release 3b</NOBR>, <NOBR>16-bit</NOBR> half-precision, +<CODE>float16_t</CODE>, is supported. +</P> + +<P> +<LI> +Functions have been added for converting between the floating-point types and +unsigned integers. +<NOBR>Release 2</NOBR> supported only signed integers, not unsigned. +</P> + +<P> +<LI> +Fused multiply-add functions have been added for all floating-point formats +except <NOBR>80-bit</NOBR> double-extended-precision, +<CODE>extFloat80_t</CODE>. +</P> + +<P> +<LI> +New rounding modes are supported: +<CODE>softfloat_round_near_maxMag</CODE> (round to nearest, with ties to +maximum magnitude, away from zero), and, as of <NOBR>Release 3c</NOBR>, +optional <CODE>softfloat_round_odd</CODE> (round to odd, also known as +jamming). +</P> + +</UL> +</P> + +<H3>9.4. Better Compatibility with the C Language</H3> + +<P> +<NOBR>Release 3</NOBR> of SoftFloat was written to conform better to the ISO C +Standard’s rules for portability. +For example, older releases of SoftFloat employed type conversions in ways +that, while commonly practiced, are not fully defined by the C Standard. +Such problematic type conversions have generally been replaced by the use of +unions, the behavior around which is more strictly regulated these days. +</P> + +<H3>9.5. New Organization as a Library</H3> + +<P> +Starting with <NOBR>Release 3</NOBR>, SoftFloat now builds as a library. +Previously, SoftFloat compiled into a single, monolithic object file containing +all the SoftFloat functions, with the consequence that a program linking with +SoftFloat would get every SoftFloat function in its binary file even if only a +few functions were actually used. +With SoftFloat in the form of a library, a program that is linked by a standard +linker will include only those functions of SoftFloat that it needs and no +others. +</P> + +<H3>9.6. Optimization Gains (and Losses)</H3> + +<P> +Individual SoftFloat functions have been variously improved in +<NOBR>Release 3</NOBR> compared to earlier releases. +In particular, better, faster algorithms have been deployed for the operations +of division, square root, and remainder. +For functions operating on the larger <NOBR>80-bit</NOBR> and +<NOBR>128-bit</NOBR> formats, <CODE>extFloat80_t</CODE> and +<CODE>float128_t</CODE>, code size has also generally been reduced. +</P> + +<P> +However, because <NOBR>Release 2</NOBR> compiled all of SoftFloat together as a +single object file, compilers could make optimizations across function calls +when one SoftFloat function calls another. +Now that the functions of SoftFloat are compiled separately and only afterward +linked together into a program, there is not usually the same opportunity to +optimize across function calls. +Some loss of speed has been observed due to this change. +</P> + + +<H2>10. Future Directions</H2> + +<P> +The following improvements are anticipated for future releases of SoftFloat: +<UL> +<LI> +more functions from the 2008 version of the IEEE Floating-Point Standard; +<LI> +consistent, defined behavior for non-canonical representations of extended +format <CODE>extFloat80_t</CODE> (discussed in <NOBR>section 4.4</NOBR>, +<I>Non-canonical Representations in <CODE>extFloat80_t</CODE></I>). + +</UL> +</P> + + +<H2>11.
