Its configure tests using g++ -will not run correctly since by default the linker will try to link against libstdc++ -which shouldn't exist yet. We need an option to disable -lstdc++ -option whilst leaving -lc, -lgcc and other automatic library dependencies added by gcc -driver. This patch adds such an option which only disables the -lstdc++. - -A "standard" gcc build uses xgcc and hence avoids this. We should ask upstream how to -do this officially, the likely answer is don't build libstdc++ separately. - -RP 29/6/10 - -Signed-off-by: Khem Raj - -Upstream-Status: Inappropriate [embedded specific] ---- - gcc/c-family/c.opt | 4 ++++ - gcc/cp/g++spec.c | 1 + - gcc/doc/invoke.texi | 32 +++++++++++++++++++++++++++++++- - gcc/gcc.c | 1 + - 4 files changed, 37 insertions(+), 1 deletion(-) - -diff --git a/gcc/c-family/c.opt b/gcc/c-family/c.opt -index 9ad2f6e1fcc..c4ef7796282 100644 ---- a/gcc/c-family/c.opt -+++ b/gcc/c-family/c.opt -@@ -1848,6 +1848,10 @@ nostdinc++ - C++ ObjC++ - Do not search standard system include directories for C++. - -+nostdlib++ -+Driver -+Do not link standard C++ runtime library -+ - o - C ObjC C++ ObjC++ Joined Separate - ; Documented in common.opt -diff --git a/gcc/cp/g++spec.c b/gcc/cp/g++spec.c -index ffcc87c79c9..28d8a9cf530 100644 ---- a/gcc/cp/g++spec.c -+++ b/gcc/cp/g++spec.c -@@ -137,6 +137,7 @@ lang_specific_driver (struct cl_decoded_option **in_decoded_options, - switch (decoded_options[i].opt_index) - { - case OPT_nostdlib: -+ case OPT_nostdlib__: - case OPT_nodefaultlibs: - library = -1; - break; -diff --git a/gcc/doc/invoke.texi b/gcc/doc/invoke.texi -index 060cd7169c6..8e2adc25644 100644 ---- a/gcc/doc/invoke.texi -+++ b/gcc/doc/invoke.texi -@@ -211,6 +211,9 @@ in the following sections. - -fno-weak -nostdinc++ @gol - -fvisibility-inlines-hidden @gol - -fvisibility-ms-compat @gol -+-fvtable-verify=@r{[}std@r{|}preinit@r{|}none@r{]} @gol -+-fvtv-counts -fvtv-debug @gol -+-nostdlib++ @gol - -fext-numeric-literals @gol - -Wabi=@var{n} -Wabi-tag -Wconversion-null -Wctor-dtor-privacy @gol - -Wdelete-non-virtual-dtor -Wliteral-suffix -Wmultiple-inheritance @gol -@@ -496,7 +499,7 @@ Objective-C and Objective-C++ Dialects}. - -s -static -static-libgcc -static-libstdc++ @gol - -static-libasan -static-libtsan -static-liblsan -static-libubsan @gol - -static-libmpx -static-libmpxwrappers @gol ---shared -shared-libgcc -symbolic @gol -+-shared -shared-libgcc -symbolic -nostdlib++ @gol - -T @var{script} -Wl,@var{option} -Xlinker @var{option} @gol - -u @var{symbol} -z @var{keyword}} - -@@ -11606,6 +11609,33 @@ library subroutines. - constructors are called; @pxref{Collect2,,@code{collect2}, gccint, - GNU Compiler Collection (GCC) Internals}.) - -+@item -nostdlib++ -+@opindex nostdlib++ -+Do not use the standard system C++ runtime libraries when linking. -+Only the libraries you specify will be passed to the linker. -+ -+@cindex @option{-lgcc}, use with @option{-nostdlib} -+@cindex @option{-nostdlib} and unresolved references -+@cindex unresolved references and @option{-nostdlib} -+@cindex @option{-lgcc}, use with @option{-nodefaultlibs} -+@cindex @option{-nodefaultlibs} and unresolved references -+@cindex unresolved references and @option{-nodefaultlibs} -+One of the standard libraries bypassed by @option{-nostdlib} and -+@option{-nodefaultlibs} is @file{libgcc.a}, a library of internal subroutines -+which GCC uses to overcome shortcomings of particular machines, or special -+needs for some languages. -+(@xref{Interface,,Interfacing to GCC Output,gccint,GNU Compiler -+Collection (GCC) Internals}, -+for more discussion of @file{libgcc.a}.) -+In most cases, you need @file{libgcc.a} even when you want to avoid -+other standard libraries.
