| | | | | | | | | | | | | softpipe throws integer division by zero exceptions on windows when using % with integers in a geometry shader. v2: Made error results consistent with existing div/mod zero handling in tgsi. 64 bit signed integer division by zero returns zero like in micro_idiv, unsigned returns ~0u like in micro_udiv.

* gallium/tgsi: Treat UCMP sources as floats to match the GLSL-to-TGSI pass ↵Francisco Jerez2017-03-151-13/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* tgsi/ureg: return correct token count in ureg_get_tokensGrazvydas Ignotas2017-03-031-1/+1
| | | | | | | | | | | | | Valgrind reports that the shader cache writes uninitialized data to disk. Turns out ureg_get_tokens() is returning the count of allocated tokens instead of how many are actually used, so the cache writes out unused space at the end. Use the real count instead. This change should not cause regressions elsewhere because the only ureg_get_tokens() user that cares about token count is the shader cache.

| | | | | | | | | | | | | | | | | | | 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]>
