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
