2010-08-02glsl2: Give the path within src/mesa/ for headers instead of relying on -I.Aras Pranckevicius
2010-07-31glsl2: Do algebraic optimizations after linking as well.Eric Anholt
Linking brings in inlining of builtins, so we weren't catching the (rcp(/sqrt(x)) -> rsq(x)) without it.
2010-07-31glsl2: Add new tree grafting optimization pass.Eric Anholt
2010-07-29glsl2: Fix spelling of "sentinel."Eric Anholt
2010-07-28glsl2: Fail linking where the FS reads a varying that the VS doesn't write.Eric Anholt
Fixes: glsl1-varying read but not written glsl1-varying var mismatch
2010-07-28glsl2: Unmark unwritten varyings as varying.Eric Anholt
This fixes an assertion failure in ir_to_mesa, and the varying won't take up varying space.
2010-07-27glsl2: Actually use the linked dead code eliminator.Eric Anholt
I managed to revert the change from unlinked at some point while cleaning up the changes. glsl-fs-raytrace-bug27060 drops from 389 instructions to 370.
2010-07-27glsl2: Use ir_dead_code's linked version after linking.Eric Anholt
glsl-fs-raytrace-bug27060 goes from 485 Mesa IR instructions to 389 before Mesa IR optimization.
2010-07-26Merge remote branch 'origin/master' into glsl2Eric Anholt
This pulls in multiple i965 driver fixes which will help ensure better testing coverage during development, and also gets past the conflicts of the src/mesa/shader -> src/mesa/program move. Conflicts: src/mesa/Makefile src/mesa/main/shaderapi.c src/mesa/main/shaderobj.h
2010-07-21linker: Link built-in functions instead of including them in every shaderIan Romanick
This is an invasive set of changes. Each user shader tracks a set of other shaders that contain built-in functions. During compilation, function prototypes are imported from these shaders. During linking, the shaders are linked with these built-in-function shaders just like with any other shader.
2010-07-20linker: Do post-link lowering and optimizationIan Romanick
The lowering code should probably be moved elsewhere.
2010-07-20glsl2: Add and use new variable mode ir_var_temporaryIan Romanick
This is quite a large patch because breaking it into smaller pieces would result in the tree being intermitently broken. The big changes are: * Add the ir_var_temporary variable mode * Change the ir_variable constructor to take the mode as a parameter and correctly specify the mode for all ir_varables. * Change the linker to not cross validate ir_var_temporary variables. * Change the linker to pull all ir_var_temporary variables from global scope into 'main'.
2010-07-19linker: Remove the FINISHME comment for intrastage linkingIan Romanick
2010-07-19linker: Remove redundant check for 'main' in shadersIan Romanick
This is now handled in link_intrastage_shaders.
2010-07-19linker: Track and validate GLSL versions used in shadersIan Romanick
2010-07-19linker: Add comment about bug in initializer handlingIan Romanick
2010-07-19linker: First bits of intrastage, intershader function linkingIan Romanick
This handles the easy case of linking a function in a different compilation unit that doesn't call any functions or reference any global variables.
2010-07-19linker: Remove some unnecessary includesIan Romanick
2010-07-19linker: Use foreach_list_safe in move_non_declarationsIan Romanick
The node being processed may be removed from the list and put in a different list. Not using the safe version caused list processing to change streams after moving a node.
2010-07-19linker: Move global instructions from the linked shader firstIan Romanick
For the shader containing 'main', use the linked shader (i.e., the clone of the original shader that contained main) as the source for global instructions to move into main.
2010-07-13glsl2: When linking makes a variable not a varying output, make it ir_var_auto.Eric Anholt
This almost fixes glsl-unused-varying, except that the used varying gets assigned to the first varying slot (position).
2010-07-13glsl2: Remove unnecessary casts of clone return valuesIan Romanick
2010-07-12linker: Merge global-scope instructions into mainIan Romanick
Find instructions in all shaders that are not contained in a function (i.e., initializers for global variables). "Move" these instructions to the top of the main function in the linked shader. As a side-effect, many global variables will also be copied into the linked shader.
2010-07-12linker: Detect the shader that contains "main" during intrastage linkingIan Romanick
2010-07-12linker: Implement first bits of intrastage linkingIan Romanick
This currently involves an ugly hack so that every link doesn't result in all the built-in functions showing up as multiply defined. As soon as the built-in functions are stored in a separate compilation unit, ir_function_signature::is_built_in can be removed.
2010-07-12linker: Refactor cross_validate_uniforms into cross_validate_globalsIan Romanick
The later, more generic function will be used in the intra-stage linker.
2010-07-12linker: Stub-out intrastage linkerIan Romanick
2010-07-07linker: Use bit-0 instead of VERT_BIT_GENERIC0Ian Romanick
Uses of the bits for allocation are offset by 16, and VERT_BIT_GENERIC0 already has the 16 offset. As a result, it was preventing the wrong thing from being allocated.
2010-06-30glsl2: Allow a fragment shader to not write a color.Eric Anholt
I can't find any text justifying this check, and it caused a reasonable-looking shader in glsl-bug-22603 (which writes only gl_FragDepth) to fail.
2010-06-30linker: Don't dynamically allocate slots for linked shadersIan Romanick
The can be at most one shader per stage. There are currently only two stages. There is zero reason to dynamically size this array.
2010-06-30linker: Don't automatically allocate VERT_ATTRIB_GENERIC0Ian Romanick
2010-06-30glsl2: Use Mesa's gl_shader_program instead of our own struct glsl_program.Eric Anholt
This avoids more allocation and shuffling of data around.
2010-06-30glsl2: Move our data from a glsl_shader* on the side to the main gl_shader *.Eric Anholt
This saves recompiling at link time. gl_shader->ir is made a pointer so that we don't have to bring exec_list into mtypes.h.
2010-06-24glsl2: Wrap includes of C interfaces with extern "C".Eric Anholt
2010-06-24glsl2: Move the compiler to the subdirectory it will live in in Mesa.Eric Anholt
