https://bugs.kde.org/show_bug.cgi?id=355231 --- Comment #3 from Julian Seward --- I think we might be talking at cross purposes. Sure, the silicon supports VMOVDQU (and other AVX insns) in both 32- and 64-bit modes. What I meant is, Valgrind doesn't; 32-bit support doesn't extend beyond SSSE3. If you want to run AVX code on Valgrind then you need to do it in a 64-bit process. -- You are receiving this mail because: You are watching all bug changes.

If vmovdqu is x86_64, then it seems like the test program should SIGILL rather than complete successfully. -- You are receiving this mail because: You are watching all bug changes.

I suggest you move to 64-bit x86 instead, which supports up to and including AVX2. -- You are receiving this mail because: You are watching all bug changes.
