[valgrind] [Bug 366142] New: Illegal opcode _mm_maskload_ps

[Marios Hadjieleftheriou via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=366142

Bug ID: 366142
   Summary: Illegal opcode _mm_maskload_ps
   Product: valgrind
   Version: 3.10.0
  Platform: Debian stable
OS: Linux
Status: UNCONFIRMED
  Severity: normal
  Priority: NOR
 Component: callgrind
  Assignee: josef.weidendor...@gmx.de
  Reporter: mha...@gmail.com

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
