* gallium: all drivers should accept two-dimensional constant buffer indexingNicolai Hähnle2017-09-041-8/+3

For the TGSI_SEMANTIC_SAMPLEPOS system value, clarify the range of positions returned. v2: use 'undef' for unused vector components.

| | | | | | | | | | | | | | pipe_draw_info::indexed is replaced with index_size. index_size == 0 means non-indexed. Instead of pipe_index_buffer::offset, pipe_draw_info::start is used. For indexed indirect draws, pipe_draw_info::start is added to the indirect start. This is the only case when "start" affects indirect draws. pipe_draw_info::index is a union. Use either index::resource or index::user depending on the value of pipe_draw_info::has_user_indices. v2: fixes for nine, svga

* 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.
