* tgsi: fix mixed data type comparison in tgsi_point_sprite.cCharmaine Lee2016-06-061-3/+3
| | | | | | | | | | | | | | | | Cast the unsigned semantic index to integer datatype before comparing to max_generic, otherwise, max_generic which is initialized to -1 will be converted to unsigned int before the comparison, causing a wrong semantic index to be assigned to a shader output. Fixes the assert running TurboCAD_gl.trace. (VMware bug 1667265) Also tested with glretrace, mesa demos pointblast, spriteblast and pointcoord. v2: use the original max_generic variable but add the (int) cast to the semantic index, as suggested by Brian.

* gallium: refactor pipe_shader_state to support multiple IR'sRob Clark2016-05-111-3/+1
| | | | | | | | | | | | | | | | The goal is to allow the pipe driver to request something other than TGSI, but detect whether what is getting is TGSI vs what it requested. The pipe drivers will always have to support TGSI (and convert that into whatever it is that they prefer), but in some cases we should be able to skip the TGSI intermediate step (such as glsl->nir vs glsl->tgsi->nir). I think pipe_compute_state should get similar treatment. Currently, afaict, it has one user and one consumer, which has allowed it to be sloppy wrt. supporting alternative IR's.
