--- Comment #11 from Henri Verbeet <hverbeet at gmail.com> --- (In reply to Marek Olšák from comment #10) > However, Tonga and later hardware doesn't have the legacy dx9 opcodes for > MUL, MAD, RCP, RSQ, and LOG and they must be emulated with a comparison (or > V_CLASS_F32 that returns whether it's NaN/+-Inf/Denorm/+-0/etc) + > conditional assignment. It's better to do the conditional assignment after > every RCP than after every MUL. Interesting, I wonder how that works out for Direct3D 9 applications. I don't suppose there's a global switch instead like (at least some) Intel and NVIDIA hardware has? -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
