Hi all, when building gcc (msys2 / mingw64 package) with the following options makepkg_mingw64.confg CFLAGS="-march=sandybridge -mtune=sandybridge -maddress-mode=long -mfpmath=sse" CXXFLAGS="-march=sandybridge -mtune=sandybridge -masm=intel -maddress-mode=long -mfpmath=sse" configure (see blow) I would expect the following target options to be set based on the documentation -march=cpu-type 'sandybridge' Intel Sandy Bridge CPU with 64-bit extensions, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, POPCNT, AVX, AES and PCLMUL instruction set support. source: http://gcc.gnu.org/onlinedocs/gcc-4.9.0/gcc/i386-and-x86-64-Options.html#i386-and-x86-64-Options But only -march=sandybridge -mtune=sandybridge are set Thanks, Andreas $ gcc -v Using built-in specs.
