But in our assembler they use exec implicitly. So I cannot imagine any relevant tests with exec. I added 2 rather formal tests instead: v_add_co_u32 v0, exec, v0, v2 v_add_co_u32 v0, exec_lo, v0, v2 This revision is now accepted and ready to land.Jul 24 2019, 9:21 AM Closed by commit rL366921: [AMDGPU][MC][GFX10] Enabled GFX10 assembly with arbitrary wavesize assumed by… (authored by dpreobra). · Explain WhyJul 24 2019, 9:51 AM This revision was automatically updated to reflect the committed changes.
