Re: fatal error: x86intrin.h: No such file or directory

Weill not exactly.
gcc-trunk/trunk$ find ./ -name x86intrin.h
./gcc/config/i386/x86intrin.h
./gcc/config/rs6000/x86intrin.h

PPC has functionally equivalent x86 intrinsic headers for MMX through SSE4,?

./gcc/config/rs6000/htmintrin.h
./gcc/config/rs6000/mmintrin.h
./gcc/config/rs6000/pmmintrin.h
./gcc/config/rs6000/xmmintrin.h
./gcc/config/rs6000/bmi2intrin.h
./gcc/config/rs6000/smmintrin.h
./gcc/config/rs6000/emmintrin.h
./gcc/config/rs6000/htmxlintrin.h
./gcc/config/rs6000/tmmintrin.h
./gcc/config/rs6000/bmiintrin.h
./gcc/config/rs6000/x86intrin.h

So it may work there, but is unlikely to work on any other platform.
