I am trying to profile a program compiled with gcc using -mavx, and including immintrin.h. I get the following error: ==5880== Process terminating with default action of signal 4 (SIGILL) ==5880== Illegal opcode at address 0x43AA5E ==5880== at 0x43AA5E: ... (avxintrin.h:928) Looking at avxintrin.h line 928, I see this instruction: 927 extern __inline __m128 __attribute__((__gnu_inline__, __always_inline__, __artificial__)) 928 _mm_maskload_ps (float const *__P, __m128i __M) 929 { 930 return (__m128) __builtin_ia32_maskloadps ((const __v4sf *)__P, 931 (__v4si)__M); 932 } Reproducible: Always Steps to Reproduce: 1. Run any executable that uses _mm_maskload_ps
I suppose you get the same error with other tools, so this is not callgrind-specific. Reassigning to general. Can you recheck with valgrind 3.11? Is this 32-bit?

I will do so soon.
