* mesa: Make _mesa_get_compressed_formats match the texture compression specsIan Romanick2011-07-253-30/+93
| | | | | | | | | | | The implementation deviated slightly from the GL_EXT_texture_sRGB spec and from other implementations. A giant comment block was added to justify the somewhat odd behavior of this function. In addition, the interface had unnecessary cruft. The 'all' parameter was false at all callers, so it has been removed. Reviewed-by: Brian Paul <[email protected]>

* glsl: Correctly return progress from lower_variable_index_to_cond_assignIan Romanick2011-07-251-1/+3
| | | | | | | | | | | | | | | | | | | | lower_variable_index_to_cond_assign runs until it can't make any more progress. It then returns the result of the last pass which will always be false. This caused the lowering loop in _mesa_ir_link_shader to end before doing one last round of lower_if_to_cond_assign. This caused several if-statements (resulting from lower_variable_index_to_cond_assign) to be left in the IR. In addition to this change, lower_variable_index_to_cond_assign should take a flag indicating whether or not it should even generate if-statements. This is easily controlled by switch_generator::linear_sequence_max_length. This would generate much better code on architectures without any flow contol. Fixes i915 piglit regressions glsl-texcoord-array and glsl-fs-vec4-indexing-temp-src. Reviewed-by: Eric Anholt <[email protected]>

* i965: Fix many of the trivial WebGL demos that broke due to IB optimization.Eric Anholt2011-07-251-0/+1
| | | | | | | | | | | The index buffer state emit only occurred if there was an IB in place and we were in either a new batch or a new IB state. But because we only flagged new IB state if IB state changed from the last IB state we calculated, we could simply never emit IB state after batchbuffer wraps if the first draw didn't use the IB and we didn't actually change the IB. Fixes piglit glx-multi-context-ib-1.

* i965: Emit texture cache flushes on gen6 along with render cache flushes.Eric Anholt2011-07-251-0/+1
| | | | | | | | | | | | | | It turns out that internally the texture cache gets flushed in a couple of cases, particularly around 2D operations mixed with 3D. In almost all cases one of those happens between rendering to an FBO-attached texture and rendering from that texture. However, as of the next patch, glean tfbo (and the new fbo-flushing-2 test) would manage to get stale texture values because one of those flushes didn't occur. The intention of this code was always to get the render cache cleared and ready to be used from the sampler cache (and it does on <= gen4), so this just catches gen5 up. This patch was also tested to fix fbo-flushing on gen7.
* i965: vs optimization fix: Check val.{negate,abs} in accumulator_contains()Paul Berry2011-07-251-0/+3
| | | | | | | | | | | | | | | | | | When emitting a MAC instruction in a vertex shader, brw_vs_emit() calls accumulator_contains() to determine whether the accumulator already contains the appropriate addend; if it does, then we can avoid emitting an unnecessary MOV instruction. However, accumulator_contains() wasn't checking the val.negate or val.abs flags. As a result, if the desired value was the negation, or the absolute value, of what was already in the accumulator, we would generate an incorrect shader. Fixes piglit test vs-refract-vec4-vec4-float. Tested on Gen5 and Gen6. Reviewed-by: Eric Anholt <[email protected]>

* i965/fs: Clear result before visiting shadow comparitor and LOD info.Kenneth Graunke2011-07-251-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | Commit 53c89c67f33639afef951e178f93f4e29acc5d53 ("i965: Avoid generating MOVs for assignments of expressions.") added the line "this->result = reg_undef" all over the code. Unfortunately, since Eric developed his patch before I landed Ivybridge support, he missed adding it to fs_visitor::emit_texture_gen7() after rebasing. Furthermore, since I developed TXD support before Eric's patch, I neglected to add it to the gradient handling when I rebased. Neglecting to set this causes the visitor to use this->result as storage rather than generating a new temporary. These missing statements resulted in the same register being used to store several different values.

* glsl: Treat ir_dereference_array of non-var as a constant for loweringIan Romanick2011-07-231-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously the code would just look at deref->array->type to see if it was a constant. This isn't good enough because deref->array might be another ir_dereference_array... of a constant. As a result, deref->array->type wouldn't be a constant, but deref->variable_referenced() would return NULL. The unchecked NULL pointer would shortly lead to a segfault. Instead just look at the return of deref->variable_referenced(). If it's NULL, assume that either a constant or some other form of anonymous temporary storage is being dereferenced. This is a bit hinkey because most drivers treat constant arrays as uniforms, but the lowering pass treats them as temporaries. This keeps the behavior of the old code, so this change isn't making things worse.

| | | | | | | | | | | | | | | | | | | | | | | | | The previous implementation could easily get tricked if the LHS of an assignment included a non-constant index that was "inside" another dereference. For example: mat4 m[2]; m[0][i] = vec4(0.0); Due to the way it tracked whether the array was being assigned, it would think that the non-constant index was in an r-value. The new code fixes that by tracking l-values and r-values differently. The index is also replaced by cloning the IR and replacing the index variable instead of the odd way it was done before. v2: Apply some simplifications suggested by Eric Anholt. Making assignment_generator::rvalue be ir_dereference instead of ir_rvalue simplified the code a bit. Fixes i965 piglit fs-temp-array-mat[234]-index-wr and vs-varying-array-mat[234]-index-wr.
