* ir_to_mesa: do not check the number of uniforms against hw limitsMarek Olšák2011-03-141-5/+3
| | | | | | | | | | | | | | | | | | | | | The r300 compiler can eliminate unused uniforms and remap uniform locations if their number surpasses hardware limits, so the limit is actually NumParameters + NumUnusedParameters. This is important for some apps under Wine to run. Wine sometimes declares a uniform array of 256 vec4's and some Wine-specific constants on top of that, so in total there is more uniforms than r300 can handle. This was the main motivation for implementing the elimination of unused constants. We should allow drivers to implement fail & recovery paths where it makes sense, so giving up too early especially when comes to uniforms is not so good idea, though I agree there should be some hard limit for all drivers. This patch fixes: - glsl-fs-uniform-array-5 - glsl-vs-large-uniform-array on drivers which can eliminate unused uniforms.
* Revert "mesa: Convert fixed function fragment program generator to GLSL IR."Eric Anholt2011-03-121-1/+1
| | | | | This reverts commit 7cb87dffce2c7a37f960f3a865cf92fd193dd8c5. There were regressions (Bug #35244) and more review has been requested.
* mesa: Convert fixed function fragment program generator to GLSL IR.Eric Anholt2011-03-111-1/+1
| | | | | | | | This is a step towards providing a direct route for drivers accepting GLSL IR for codegen. Perhaps more importantly, it runs the fixed function fragment program through the GLSL IR optimization. Having seen how easy it is to make ugly fixed function texenv code that can do unnecessary work, this may improve real applicatinos.
* prog_cache: Add some support for shader_programs in prog_cache.Eric Anholt2011-03-112-4/+58
| | | | | | This is used in the upcoming fixed function shader_program generation, and shader_program and ARB programs are together in this code until both fragment and vertex ff get converted.
* mesa: test against MaxUniformComponents in check_resources()Brian Paul2011-03-111-3/+3
| | | | | | Since we're compiling/linking GLSL shaders we should check against the shader uniform limits, not the legacy vertex/fragment program parameter limits which are usually lower.
* mesa: move location of some geometry program limitsBrian Paul2011-03-111-1/+1
| | | | | | | The gl_program_constants struct is for limits that are applicable to any/all shader stages. Move the geometry shader-only fields into the gl_constants struct. Remove redundant MaxGeometryUniformComponents field too.
* mesa: use check_resources() to check program against limitsBrian Paul2011-03-111-0/+58
| | | | | | Without these checks we could create shaders with more samplers, constants than the driver could handle. Fail linking rather than dying later.

* mesa: Do copy propagation across if-else-endif.José Fonseca2011-02-171-2/+28
| | | | | | | | Addresses excessive TEMP allocation in vertex shaders where all CONSTs are stored into TEMPS at the start, but copy propagation was failing due to the presence of IFs. We could do something about loops, but ifs are easy enough.
* ir_to_mesa: Don't dereference a NULL pointer during copy propagationIan Romanick2011-02-111-0/+3
| | | | | | The ACP may already be NULL, so don't try to make it NULL again. This should fix bugzilla #34119.

* ra: Use the same context when realloc'ing arrays.Kenneth Graunke2011-01-211-2/+2
| | | | | | 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.
* ra: Take advantage of the adjacency list in finding a node to spill.Eric Anholt2011-01-181-6/+6
| | | | | | | | 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).

* ra: Take advantage of the adjacency list in ra_select() too.Eric Anholt2011-01-181-5/+6

* ra: Add an adjacency list to trade space for time in ra_simplify().Eric Anholt2011-01-181-14/+21
| | | | | | 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).
* ra: Trade off some space to get time efficiency in ra_set_finalize().Eric Anholt2011-01-181-6/+32
| | | | | | | | | | | | | | | | | 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.

* | mesa: Add channel-wise copy propagation to ir_to_mesa.Eric Anholt2011-01-141-0/+129
| | | | | | | | | | | | | | | | 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.

* | glsl: Support if-flattening beyond a given maximum nesting depth.Kenneth Graunke2010-12-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | 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.
