* nir: Fix the Mesa build without -DDEBUG.Kenneth Graunke2015-02-201-2/+2
| | | | | | | | | | | | | With -DDEBUG -UNDEBUG, this assert uses reg_state::stack_size, which doesn't exist, breaking the build: assert(state->states[index].index < state->states[index].stack_size); Switch it to ifndef NDEBUG, so the field will exist if the assertion actually generates code.

* mesa: Make bitset.h not rely on Mesa-specific types and functions.Eric Anholt2015-02-201-4/+3
| | | | | | | | | | Note that we can't use u_math.h's align() because it's a function instead of a macro, while BITSET_DECLARE needs a constant expression for nouveau's usage in global declarations. v2: Stick some parens around the bits macro argument usage (review by Jose).

| | | | | | | | | | | | | | | This reverts 73c2b0d18c51459697d8ec194ecfc4438c98c139. It doesn't seem to be reliable. It's probably missing a wait packet or something, because it's just a register write and doesn't wait for anything. SURFACE_SYNC at least seems to wait until the flush is done. Just guessing. Let's not complicate things and revert this. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=88561 Cc: 10.5 <[email protected]> Reviewed-by: Alex Deucher <[email protected]>
* i965/gen6: Fix GL_GEOMETRY_SHADER_PRIMITIVES_EMITTED_ARBIago Toral Quiroga2015-02-201-0/+5
| | | | | | | | | | | | | | | | | | | In gen6 we need to compute the primitive count in the generated GS program. The current implementation only counts full primitives, that is, if the output primitive type is a triangle strip, it won't count individual triangles in the strip, only complete strips. If we want to count basic primitives instead we have two options: rework the assembly code we generate for strip primitives or simply use CL_INVOCATION_COUNT to resolve the query and let the hardware do that work for us. This patch implements the latter approach.

* vc4: Enforce one-uniform-per-instruction after optimization.Eric Anholt2015-02-196-50/+209
| | | | | | | | | | | | | | | This lets us more intelligently decide which uniform values should be put into temporaries, by choosing the most reused values to push to temps first. total uniforms in shared programs: 13457 -> 13433 (-0.18%) uniforms in affected programs: 1524 -> 1500 (-1.57%) total instructions in shared programs: 40198 -> 40019 (-0.45%) instructions in affected programs: 6027 -> 5848 (-2.97%) I noticed this opportunity because with the NIR work, some programs were happening to make different uniform copy propagation choices that significantly increased instruction counts.

Take for instance: 1: add(8) dst0 src0 src1 2: mov.sat(8) dst1 -dst0 3: mov.sat(8) dst2 dst0 Consider such an instruction to interfere.

The next commit will change this to return null if it's the first instruction. Making this change first avoids getting a segfault between commits.
