* gallium/tgsi: Treat UCMP sources as floats to match the GLSL-to-TGSI pass ↵Francisco Jerez2017-03-151-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | expectations. Currently the GLSL-to-TGSI translation pass assumes it can use floating point source modifiers on the UCMP instruction. See the bug report linked below for an example where an unrelated change in the GLSL built-in lowering code for atan2 (e9ffd12827ac11a2d2002a42fa8eb1) caused the generation of floating-point ir_unop_neg instructions followed by ir_triop_csel, which is translated into UCMP with a negate modifier on back-ends with native integer support. Allowing floating-point source modifiers on an integer instruction seems like rather dubious design for a transport IR, since the same semantics could be represented as a sequence of MOV+UCMP instructions instead, but supposedly this matches the expectations of TGSI back-ends other than tgsi_exec, and the expectations of the DX10 API. I take no responsibility for future headaches caused by this inconsistency. Fixes a regression of piglit glsl-fs-tan-1 on softpipe introduced by the above-mentioned glsl front-end commit. Even though the commit that triggered the regression doesn't seem to have made it to any stable branches yet, this might be worth back-porting since I don't see any reason why the bug couldn't have been reproduced before that point.

Even though such a library could be written, there's no big advantage to do it that way for now given that int64 is a very uncommon use-case.

| | | | | | | | | | | | | | | | | | | Make the cap consistent with PIPE_CAP_INT64. Aside from the hypothetical case of using draw for vertex shaders (and actually caring about doubles...), every implementation supports doubles either nowhere or everywhere. Also, st/mesa didn't even check the cap correctly in all supported shader stages. While at it, add a missing LLVM version check for 64-bit integers in radeonsi. This is conservative: judging by the log, LLVM 3.8 might be sufficient, but there are probably bugs that have been fixed since then. v2: fix clover (Marek) Reviewed-by: Marek Olšák <[email protected]>

* tgsi: align the definition of BFI & [UI]BFE with GLSLNicolai Hähnle2016-11-021-20/+15
| | | | | | | | | | | | | | | As previously written, these opcodes use the SM5 semantics which is incompatible with GLSL when bits == 0, offset == 32. At some point we may want to add BFI_SM5 etc. opcodes, but all users currently either want (and expect!) the GLSL semantics or don't care. Bitfield inserts are generated by the GLSL lower_instructions and lower_packing_builtins passes with constant bits and offset arguments, so any workaround code that drivers may have to emit to follow GLSL semantics should be optimized away easily for those uses.
