* glsl2: Conditionally define preprocessor tokens for optional extensionsIan Romanick2010-07-017-12/+25
| | | | | The only optional extension currently supported by the compiler is GL_EXT_texture_array.
* glsl2: Define preprocessor tokens for extensionsIan Romanick2010-07-011-1/+17
| | | | | | Currently only GL_ARB_draw_buffers and GL_ARB_texture_rectangle are defined because those extensions are always enabled. This make tex_rect-03.frag pass.
* glsl2: Support AST-to-IR translation of invariant keywordIan Romanick2010-07-011-14/+70
|
* glsl2: Initialize ast_declarator_list::invariant in constructorIan Romanick2010-07-011-0/+1
|
* glsl2: Don't bounds check unsize array redeclarationsIan Romanick2010-07-011-1/+1
| | | | This along with several previous commits fix test CorrectUnsizedArray.frag.
* glsl2: Add gl_MaxTextureCoordsIan Romanick2010-07-015-22/+24
|
* glsl2: Default delcaration of gl_TexCoord is unsizedIan Romanick2010-07-012-11/+34
|
* glsl2: Change order of semaintic checks on variable declarationsIan Romanick2010-07-011-61/+61
| | | | This will make it easier to support more (valid) kinds of redeclarations.
* ir_to_mesa: Fill in remaining ops, remove default case for expression types.Eric Anholt2010-07-011-7/+4
| | | | | We should now have support for all the expression types we need for GLSL 1.20.
* ir_to_mesa: Add support for ir_unop_rcp.Eric Anholt2010-07-011-0/+3
| | | | This isn't used at the moment, but will be soon.
* glsl2: Update README for what I've been thinking about with expr types work.Eric Anholt2010-07-011-1/+38
|
* glsl2: Add a pass to convert mod(a, b) to b * fract(a/b).Eric Anholt2010-07-018-7/+120
| | | | This is used by the Mesa IR backend to implement mod, fixing glsl-fs-mod.
* glsl2: Remove dead member from dead code visitor.Eric Anholt2010-07-011-1/+0
|
* glsl2: Add ir_unop_fract as an expression type.Eric Anholt2010-07-016-8/+33
| | | | | Most backends will prefer seeing this to seeing (a - floor(a)), so represent it explicitly.
* ir_to_mesa: Add support for discard instructions.Eric Anholt2010-06-301-2/+3
| | | | Fixes glsl-fs-discard-01.
* glsl2: Don't break sign() down by vector components.Eric Anholt2010-06-302-32/+6
|
* ir_to_mesa: Add support for ir_unop_sign.Eric Anholt2010-06-301-0/+3
| | | | Fixes glsl-fs-sign, glsl-vs-sign.
* i965: Add support for OPCODE_SSG.Eric Anholt2010-06-305-0/+54
| | | | | The old compiler didn't use SSG, and instead emitted SGT/SGT/SUB. We can do a little better for SSG than we do for the SGT series.
* ir_to_mesa: Add missing no-op type conversions.Eric Anholt2010-06-301-0/+2
| | | | Fixes glsl-fs-step.
* glsl2: Fix reversed value of step().Eric Anholt2010-06-302-38/+38
| | | | It's 0.0 if x < edge, not 1.0. Partial fix for glsl-fs-step.
* ir_to_mesa: Note which of our expr ops are unsupported 1.30 features.Eric Anholt2010-06-301-0/+11
|
* glsl2: Fix up the implementation of fract() for vector types.Eric Anholt2010-06-302-30/+6
| | | | There's no need to split each vector component out, just do vector ops.
* ir_to_mesa: Initialize the (we never use it) abs field of Mesa src regs.Eric Anholt2010-06-301-0/+1
|
* ir_to_mesa: Send the negate field on to Mesa IR.Eric Anholt2010-06-301-0/+2
| | | | Fixes glsl-fs-neg.
* ir_to_mesa: When generating a swizzle, respect the reg's current swizzle.Eric Anholt2010-06-301-5/+5
| | | | Fixes depth-tex-modes-glsl.
* glsl2: Implement AST->HIR support for the "discard" instruction.Kenneth Graunke2010-06-301-1/+1
|
* glsl2: Define new ir_discard instruction.Kenneth Graunke2010-06-3011-0/+115
|
* ir_to_mesa: Support gl_FragDepth.Eric Anholt2010-06-301-1/+1
| | | | Fixes glsl-bug-22603.
* glsl2: Allow a fragment shader to not write a color.Eric Anholt2010-06-301-6/+0
| | | | | | 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.
* mesa: Don't look in unallocatd param slots for parameter values.Eric Anholt2010-06-301-1/+1
| | | | | | | | | | glsl-derivs would add 40.0, 0.0, and 1.0 in order. When we went looking for 0.0, we'd find it in the second slot of the param, and use it, but param->Size would still be 1. When we went to add 1.0 and didn't find it, we'd put allocate it to that second slot and the 0.0 would actualy end up being 1.0. Fixes glsl-derivs, glsl-deriv-varyings.
* ir_to_mesa: Fix the indexing of attributes in the program's Attributes.Eric Anholt2010-06-301-1/+1
| | | | | This fixes GetAttribLocation returning VERT_ATTRIB_GENERIC1 instead of 1, caught by glsl-dlist-getattriblocation.
* glsl2: Fix storing of dead memory in the symbol table.Kenneth Graunke2010-06-301-2/+2
| | | | | decl->identifier is part of the AST, so it doesn't live very long. Instead, add var->name which is owned by var.
* glsl2: Preprocessed source doesn't need to live past compile time.Kenneth Graunke2010-06-302-8/+2
|
* glsl2: Create new talloc contexts the "right" way.Kenneth Graunke2010-06-302-2/+2
|
* glsl2: Use _mesa_glsl_parse_state as the talloc parent, not glsl_shader.Kenneth Graunke2010-06-306-120/+120
| | | | | | | | | | | | | _mesa_glsl_parse_state should be the parent for all temporary allocation done while compiling a shader. glsl_shader should only be used as the parent for the shader's final IR---the _result_ of compilation. Since many IR instructions may be added or discarded during optimization passes, IR should not ever be allocated to glsl_shader directly. Done via sed -i s/talloc_parent(state)/state/g and s/talloc_parent(st)/st/g. This also removes a ton of talloc_parent calls, which may help performance.
* glsl2: Steal the live IR and free the rest of the junk.Kenneth Graunke2010-06-302-0/+22
|
* linker: Don't dynamically allocate slots for linked shadersIan Romanick2010-06-302-3/+6
| | | | | The can be at most one shader per stage. There are currently only two stages. There is zero reason to dynamically size this array.
* ir_to_mesa: Tell Mesa about our choices for vertex attribute locations.Eric Anholt2010-06-301-0/+9
|
* linker: Don't automatically allocate VERT_ATTRIB_GENERIC0Ian Romanick2010-06-301-0/+6
|
* glsl2: Use Mesa's gl_shader_program instead of our own struct glsl_program.Eric Anholt2010-06-306-66/+36
| | | | This avoids more allocation and shuffling of data around.
* glsl2: Make function names and variable names be children of the node.Eric Anholt2010-06-301-3/+2
| | | | This avoids losing their memory when the parser state is freed.
* glsl2: Move our data from a glsl_shader* on the side to the main gl_shader *.Eric Anholt2010-06-307-125/+95
| | | | | 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.
* ir_to_mesa: Add support for ir_unop_abs.Eric Anholt2010-06-291-0/+4
|
* ir_to_mesa: Add support for dFdx, dFdy.Eric Anholt2010-06-291-0/+8
|
* ir_to_mesa: Start adding support for texture instructions.Eric Anholt2010-06-292-2/+142
| | | | | | | Fixes: glsl-fs-bug25902 glsl-fs-sampler-numbering glsl-lod-bias
* glsl2: Keep the same number of components in implicit conversions.Kenneth Graunke2010-06-291-0/+6
| | | | Fixes piglit test glsl-implicit-conversion-01.
* glsl2: Make gl_MaxDrawBuffers available in the vertex shaderIan Romanick2010-06-291-32/+42
|
* glsl2: Make gl_MaxDrawBuffers available in the fragment shaderIan Romanick2010-06-291-0/+15
|
* glsl2: Make gl_FragData be available in GLSL 1.10 tooIan Romanick2010-06-291-12/+5
|
* glsl2: Pass MaxDrawBuffers from core Mesa into the GLSL compilerIan Romanick2010-06-294-24/+35
