2011-01-25ir_to_mesa: Add several assertions about sizes of arraysIan Romanick
Both of these assertions are triggered by the test case in bugzilla size of 0.
2011-01-21ra: Use the same context when realloc'ing arrays.Kenneth Graunke
The original allocations use regs->regs as the context, so talloc will happily ignore the context given here. Change it to match to clarify that it isn't changing.
2011-01-18ra: Take advantage of the adjacency list in finding a node to spill.Eric Anholt
This revealed a bug in ra_get_spill_benefit where we only considered the benefit of the first adjacency we were to remove, explaining some of the ugly spilling I've seen in shaders. Because of the reduced spilling, it reduces the runtime of glsl-fs-convolution-1 36.9% +/- 0.9% (n=5).
2011-01-18ra: Remove unused "name" field in regs.Eric Anholt
2011-01-18ra: Take advantage of the adjacency list in ra_select() too.Eric Anholt
Reduces runtime of glsl-fs-convolution-1 another 13.9% +/- 0.6% (n=5).
2011-01-18ra: Add an adjacency list to trade space for time in ra_simplify().Eric Anholt
This was recommended in the original paper, but I figued "make it run" before "make it fast". Now we make it fast. Reduces the runtime of glsl-fs-convolution-1 by 12.7% +/- 0.6% (n=5).
2011-01-18ra: Trade off some space to get time efficiency in ra_set_finalize().Eric Anholt
Our use of the register allocator in i965 is somewhat unusual. Whereas most architectures would have a smaller set of registers with fewer register classes and reuse that across compilation, we have 1, 2, and 4-register classes (usually) and a variable number up to 128 registers per compile depending on how many setup parameters and push constants are present. As a result, when compiling large numbers of programs (as with glean texCombine going through ff_fragment_shader), we spent much of our CPU time in computing the q[] array. By keeping a separate list of what the conflicts are for a particular reg, we reduce glean texCombine time 17.0% +/- 2.3% (n=5). We don't expect this optimization to be useful for 915, which will have a constant register set, but it would be useful if we were switch to this register allocator for Mesa IR.

2011-01-14mesa: Add channel-wise copy propagation to ir_to_mesa.Eric Anholt
This catches more opportunities than the prog_optimize.c code on openarena's fixed function shaders turned to GLSL, mostly due to looking at multiple source instructions for copy propagation opportunities. It should also be much more CPU efficient than prog_optimize.c's code.
2011-01-09mesa: Include mfeatures.h in program.c.Vinson Lee
Include mfeatures.h for feature tests.
2010-12-27glsl: Support if-flattening beyond a given maximum nesting depth.Kenneth Graunke
This adds a new optional max_depth parameter (defaulting to 0) to lower_if_to_cond_assign, and makes the pass only flatten if-statements nested deeper than that. By default, all if-statements will be flattened, just like before. This patch also renames do_if_to_cond_assign to lower_if_to_cond_assign, to match the new naming conventions.

2010-12-13ir_to_mesa: Don't generate swizzles for record derefs of non-scalar/vectorsIan Romanick
This is the same as what the array dereference handler does. Fixes piglit test glsl-link-struct-array (bugzilla #31648). NOTE: This is a candidate for the 7.9 and 7.10 branches.

2010-12-03mesa, st/mesa: fix gl_FragCoord with FBOs in GalliumMarek Olšák
gl_FragCoord.y needs to be flipped upside down if a FBO is bound. This fixes: - piglit/fbo-fragcoord - https://bugs.freedesktop.org/show_bug.cgi?id=29420 Here I add a new program state STATE_FB_WPOS_Y_TRANSFORM, which is set based on whether a FBO is bound. The state contains a pair of transformations. It can be either (XY=identity, ZW=transformY) if a FBO is bound, or (XY=transformY, ZW=identity) otherwise, where identity = (1, 0), transformY = (-1, height-1). A classic driver (or st/mesa) may, based on some other state, choose whether to use XY or ZW, thus negate the conditional "if (is a FBO bound) ...". The reason for this is that a Gallium driver is allowed to only support WPOS relative to either the lower left or the upper left corner, so we must flip the Y axis accordingly again. (the "invert" parameter in emit_wpos_inversion) NOTE: This is a candidate for the 7.9 branch. Signed-off-by: Marek Olšák <maraeo@gmail.com> Signed-off-by: Brian Paul <brianp@vmware.com>

2010-12-01glsl: Add a lowering pass to move discards out of if-statements.Kenneth Graunke
This should allow lower_if_to_cond_assign to work in the presence of discards, fixing bug #31690 and likely #31983. NOTE: This is a candidate for the 7.9 branch.

2010-11-19ir_to_mesa: Detect and emit MOV_SATs for saturate constructs.Eric Anholt
The goal here is to avoid regressing performance on ir_to_mesa drivers for fixed function fragment shaders requiring saturates.
2010-11-19glsl: Combine many instruction lowering passes into one.Kenneth Graunke
This should save on the overhead of tree-walking and provide a convenient place to add more instruction lowering in the future. Signed-off-by: Ian Romanick <ian.d.romanick@intel.com>
2010-11-19glsl: Add ir_quadop_vector expressionIan Romanick
The vector operator collects 2, 3, or 4 scalar components into a vector. Doing this has several advantages. First, it will make ud-chain tracking for components of vectors much easier. Second, a later optimization pass could collect scalars into vectors to allow generation of SWZ instructions (or similar as operands to other instructions on R200 and i915). It also enables an easy way to generate IR for SWZ instructions in the ARB_vertex_program assembler.
