+Subject: [PATCH] Silenced -Wcast-function-type, -Wsizeof-pointer-div and
+ -Wstringop-truncation options of GCC 8.1
+
+Current GFX source code will get compilation error with GCC 8.1,
+because it is defined in makefile to use -Wall to enable all Warnings
+check.
+-Wcast-function-type, -Wsizeof-pointer-div and -Wstringop-truncation
+are new Warnings from GCC 8.
