--- Comment #16 from Julian Seward <jsew...@acm.org> --- (In reply to Tanya from comment #9) > Created attachment 109005 [details] > Nulgrind test for the serial vFMA instructions > > The "AVX-512_prototype_v3" patch changes the behaviour of the serial vFMA > instructions. For these instructions, Valgrind sets destination bits > [127:64] or [127:32] to zero; according to the ISE, these bits should remain > unchanged. The test covers the changed instructions. If I understand this right, that means the existing cases for serial vFMA insns are wrong, and also the VEX implementation is wrong. Is that correct? If so, shouldn't we just fix both the test case and implementation? -- You are receiving this mail because: You are watching all bug changes.
