* glsl2: Give IR nodes a type field.Eric Anholt2010-07-193-10/+70
| | | | | | | This is a big deal for debugging if nothing else ("what class is this ir_instruction, really?"), but is also nice for avoiding building a whole visitor or an if (node->as_whatever() || node->as_other_thing()) chain.
* ir_to_mesa: Do validation on the IR tree.Eric Anholt2010-07-191-0/+4
|
* ir_to_mesa: Don't do lowering passes on an errored-out shader.Eric Anholt2010-07-191-6/+6
|
* ir_to_mesa: Rename struct temp_entry, which is used for all variables now.Eric Anholt2010-07-181-35/+36
|
* ir_to_mesa: Add support for function calls.Eric Anholt2010-07-181-6/+227
| | | | | Unlike the previous compiler, in this case we emit only one copy of the function regardless of how many times it's called.
* glsl2: Remove the const disease from function signature's callee.Eric Anholt2010-07-185-9/+8
|
* glsl2: Make cross() be an expression operation.Eric Anholt2010-07-186-22/+21
| | | | | | ARB_fp, ARB_vp, Mesa IR, and the 965 vertex shader all have instructions for cross. Shaves 12 Mesa instructions off of a 66-instruction shader I have.
* glsl2: Fix warning from always-false assert not being known to not return.Eric Anholt2010-07-181-0/+1
|
* ast_function: Actually do type conversion on function arguments.Kenneth Graunke2010-07-141-3/+8
|
* exec_list: Add a new replace_with method.Kenneth Graunke2010-07-141-0/+11
|
* Refresh autogenerated file builtin_function.cpp.Kenneth Graunke2010-07-141-189/+27
|
* glsl2/builtins: Rework clamp to use scalar/vector combinations.Kenneth Graunke2010-07-142-45/+9
|
* glsl2/builtins: Rework min/max to use scalar/vector combinations.Kenneth Graunke2010-07-144-144/+18
|
* ir_constant_expression: Add support for ir_binop_mod.Kenneth Graunke2010-07-141-0/+27
|
* ir_constant_expression: Add support for ir_binop_min and ir_binop_max.Kenneth Graunke2010-07-141-0/+47
| | | | | These now work on scalar/vector combos. Semantically, if a is a scalar, min(a, vec2(x,y)) == vec2(min(a,x), min(a,y))
* ir_constant_expression: Add support for ir_binop_pow.Kenneth Graunke2010-07-141-0/+7
|
* ir_constant_expression: Add support for ir_unop_cos.Kenneth Graunke2010-07-141-0/+7
|
* ir_constant_expression: Add support for ir_unop_sin.Kenneth Graunke2010-07-141-0/+7
|
* ir_constant_expression: Add support for ir_unop_floor.Kenneth Graunke2010-07-141-0/+7
|
* ir_constant_expression: Add support for ir_unop_ceil.Kenneth Graunke2010-07-141-0/+7
|
* ir_constant_expression: Add support for ir_unop_trunc.Kenneth Graunke2010-07-141-0/+7
| | | | This uses a C99 function.
* ir_constant_expression: Add support for ir_unop_log2.Kenneth Graunke2010-07-141-0/+7
| | | | This uses a C99 function.
* ir_constant_expression: Add support for ir_unop_exp2.Kenneth Graunke2010-07-141-0/+7
| | | | This uses a C99 function.
* ir_constant_expression: Add support for ir_unop_sign.Kenneth Graunke2010-07-141-0/+18
|
* ir_constant_expression: Remove bogus assert in ir_unop_abs case.Kenneth Graunke2010-07-141-1/+0
| | | | abs is defined for integral types; it's even implemented.
* glsl2: Remove ir_program bong hits.Kenneth Graunke2010-07-141-4/+0
|
* ir_to_mesa: Add convenience function for opcodes with no src/dst reg.Eric Anholt2010-07-131-20/+21
| | | | Most of flow control is like this.
* glsl2: When linking makes a variable not a varying output, make it ir_var_auto.Eric Anholt2010-07-131-1/+4
| | | | | This almost fixes glsl-unused-varying, except that the used varying gets assigned to the first varying slot (position).
* ir_to_mesa: Add support for variable array indexing of builtin varyings.Eric Anholt2010-07-131-32/+62
| | | | | That is to say, gl_TexCoord[i] now works, fixing glsl-texcoord-array on swrast.
* ir_to_mesa: Add support for array dereferences on the LHS of assignments.Eric Anholt2010-07-131-29/+67
| | | | | | | | | | The big change is to delay address reg setup until the instruction that needs the deref. It was hard to use the deref chain support for the LHS because it does the copy of the dereffed value to a temporary (to avoid problems when two src regs are array derefs), so we wouldn't haev a pointer to actual storage in the end. Fixes glsl-vs-arrays on swrast.
* glsl2: Remove unnecessary casts of clone return valuesIan Romanick2010-07-132-27/+23
|
* ir_to_mesa: Rely on ir_mat_op_to_vec for matrix multiplication support.Eric Anholt2010-07-121-83/+5
|
* glsl2: Add matrix multiplication to ir_mat_op_to_vec.Eric Anholt2010-07-121-9/+188
|
* ir_to_mesa: Emit OPCODE_MAD when we find an ADD of a MUL.Eric Anholt2010-07-121-0/+36
| | | | Bug #27914.
* glsl2: Flatten expression that appear as the parameters of ir_call as well.Eric Anholt2010-07-121-5/+12
|
* glsl2: Flatten expressions that appear as the children of ir_return as well.Eric Anholt2010-07-121-5/+3

* linker: Merge global-scope instructions into mainIan Romanick2010-07-121-0/+121
| | | | | | | | 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.
* linker: Detect the shader that contains "main" during intrastage linkingIan Romanick2010-07-121-5/+45
|
* ir_function: Make matching_signature not return constIan Romanick2010-07-122-2/+2
| | | | | | | The linker needs to use this function to get specific function signatures, but it also needs to modify the returned signature. Since this method isn't itself const (i.e., const this pointer), there is no value in making a const and non-const version.
* linker: Implement first bits of intrastage linkingIan Romanick2010-07-124-2/+63
| | | | | | | 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.
* linker: Refactor cross_validate_uniforms into cross_validate_globalsIan Romanick2010-07-121-13/+54
| | | | The later, more generic function will be used in the intra-stage linker.
* glsl2: Use a better talloc context for ir_expression_flattening.Eric Anholt2010-07-121-1/+1
| | | | | | The instruction can be hung off of any other in the tree, even if the other one will be deleted, since it'll get stolen to the shader's context later if it's still live.
* glsl2: Add support for variable vector indexing on the LHS of assignments.Eric Anholt2010-07-121-3/+57
| | | | Fixes glsl-vs-vec4-indexing-3.
* glsl2: Fix copy propagation in the presence of derefs in array indexes.Eric Anholt2010-07-121-3/+22
| | | | | | We would clear the in_lhs flag early, avoiding copy propagation on the array index variable (oops) and then copy propagating on the array variable (ouch). Just avoid all copy propagation on the LHS instead.
* ir_to_mesa: Add support for dereferencing matrices from arrays.Eric Anholt2010-07-121-8/+16
|
* ir_validate: Also perform usual checks on ir_dereference_variable nodesIan Romanick2010-07-121-0/+2
|
* ir_validate: Validate that varibles are declared before used in IRIan Romanick2010-07-121-2/+26
|
* linker: Stub-out intrastage linkerIan Romanick2010-07-123-20/+92
|
* Make shader_api.h be C++ friendlyIan Romanick2010-07-121-0/+6
|
* ir_validate: Additional function related invariant checksIan Romanick2010-07-121-0/+60
| | | | | | | | | Add two invariant checks related to functions and function signatures: 1. Ensure that function definitions (ir_function) are not nested. 2. Ensure that the ir_function pointed to by an ir_function_signature is the one that contains it in its signatures list.
