2010-08-18mesa: Fix the whining for link failures to actually be under MESA_GLSL=dump.Eric Anholt
2010-08-18mesa: Don't try to free components of a NULL uniform list.Eric Anholt
This might happen if we manage to trigger the right linker errors.
2010-08-18ir_to_mesa: Fix leak by improper freeing of a uniform list.Eric Anholt
2010-08-18ir_to_mesa: Don't leak the whole linked assembly program.Eric Anholt
2010-08-18ir_to_mesa: Fix leak of set_branchtargets temp data.Eric Anholt
2010-08-18ir_to_mesa: Stop leaking the ir_instruction * annotation of our compile.Eric Anholt
2010-08-18mesa: Free old linked shaders when relinking new shaders.Eric Anholt
2010-08-18ir_to_mesa: Free the ir_to_mesa temporary storage when we're done.Eric Anholt
2010-08-18mesa: Hang the compiled shader off the shader->ir, not the shader.Eric Anholt
Otherwise, with repeated program recompile, we never free the results of the previous compile.
2010-08-18mesa: Make MESA_GLSL=dump include when compile/link fails, and the info log.Eric Anholt
2010-08-17ir_to_mesa: Allow ir_return in main().Eric Anholt
I didn't expect that this would really work, but it turns out there are shaders in the wild that do it. Fixes: (with swrast) glsl-fs-main-return glsl-vs-main-return
2010-08-17ir_to_mesa: Fix implementation of ir_binop_equal, ir_binop_notequal.Eric Anholt
These binops are the vector-to-bool comparisons, not vec-to-bvec. We likely want both operations avilable as expression, since 915 and 965 FS naturally does the vector version, while 965 VS can also naturally do the scalar version. However, we can save that until later. Fixes: glsl-fs-vec4-operator-equal.shader_test glsl-fs-vec4-operator-notequal.shader_test glsl-vs-vec4-operator-equal.shader_test glsl-vs-vec4-operator-notequal.shader_test
2010-08-17prog_optimize: Only merge writes to temporary registersBenjamin Segovia
In one optimization pass, register files may have been messed therefore merging instructions which use the same index in two different register files.
2010-08-17mesa: Dump shader source before validating the shader.Eric Anholt
This will make extracting source to produce minimal testcases for shader compile issues easier.

2010-08-13Merge branch 'master' into glsl2Ian Romanick
2010-08-13glsl2: Move ir_to_mesa handling to driver CompileShader and LinkShader hooks.Eric Anholt
This lets drivers override ir_to_mesa with their own codegen, or at least have a native alternative.
2010-08-13glsl2: Move the common optimization passes to a helper function.Eric Anholt
These are passes that we expect all codegen to be happy with. The other lowering passes for Mesa IR are moved to the Mesa IR generator.

2010-08-10mesa: additional program limit assertionsBrian Paul
2010-08-09glsl2: Add a pass to transform ir_binop_sub to add(op0, neg(op1))Eric Anholt
All the current HW backends transform subtract to adding the negation, so I haven't bothered peepholing it back out in Mesa IR. This allows some subtract of subtract to get removed in ir_algebraic.
2010-08-09glsl2: Add constant propagation.Eric Anholt
Whereas constant folding evaluates constant expressions at rvalue nodes, constant propagation tracks constant components of vectors across execution to replace (possibly swizzled) variable dereferences with constant values, triggering possible constant folding or reduced variable liveness.
2010-08-06glsl2: Move gl_program->InputsRead/OutputsWritten setting to an ir pass.Eric Anholt
This lets us handle arrays much better than trying to work backwards from assembly. Fixes fbo-drawbuffers-maxtargets on swrast (i965 needs loop unrolling)
2010-08-06ir_to_mesa: Add support for sampler arrays.Eric Anholt
Support for samplers in general is still incomplete -- anything in a uniform struct will still be broken. But that doesn't appear to be any different from master. Fixes: glsl-fs-uniform-sampler-array.shader_test
2010-08-06glsl2: Don't assert in a couple of places when encountering sampler arrays.Eric Anholt
Fixes glean shaderAPI.
2010-08-06ir_to_mesa: Give the expected size for _mesa_add_attribute().Eric Anholt
Fixes a failure in glean shaderAPI.
2010-08-05ir_to_mesa: Handle texture-array samplersIan Romanick
Fixes piglit test array_texture.
2010-08-05glsl2: Add a pass to convert exp and log to exp2 and log2.Eric Anholt
Fixes ir_to_mesa handling of unop_log, which used the weird ARB_vp LOG opcode that doesn't do what we want. This also lets the multiplication coefficients in there get constant-folded, possibly. Fixes: glsl-fs-log
2010-08-05ir_to_mesa: Don't do function inlining until linking.Eric Anholt
Optimizations at compile time should generally be done with the goal of reducing instruction count so that other work, particularly linking, is less time-consuming if the shader is used multiple times. However, function inlining increases instruction count for the inlined function bodies without removing the original function body, since we don't know if it will be used at link time or not. Reduces the runtime of linking and executing a Yo Frankie fragment shader from 0.9 seconds to 0.5 seconds (-45.9%, +/- 2.2%, n=5).
2010-08-05glsl2: Don't try to dump GLSL IR for a shader that didn't compile.Eric Anholt
