* glsl2: Don't validate IR if there were compilation errorsIan Romanick2010-07-201-3/+3
|
* linker: Remove the FINISHME comment for intrastage linkingIan Romanick2010-07-191-1/+2
|
* linker: Remove redundant check for 'main' in shadersIan Romanick2010-07-191-10/+0
| | | | This is now handled in link_intrastage_shaders.
* linker: Track and validate GLSL versions used in shadersIan Romanick2010-07-192-0/+22
|
* glsl2: Use Elements macroIan Romanick2010-07-192-11/+18
|
* linker: Recursively resolve function calls in imported functionsIan Romanick2010-07-191-3/+46
|
* linker: look up function signatures during linking instead of using calleeIan Romanick2010-07-191-24/+59
| | | | | | | Instead of using ir_call::callee, search for the signature in the linked shader. This will allow resolving calls from functions imported from other shaders. The ir_call::callee pointer in the imported function will still reference a signature in the original shader.
* linker: Pull find_matching_signature out of call_link_visitorIan Romanick2010-07-191-21/+27
| | | | | | The list of shaders to search needs to be provided as an explicit parameter to support coming changes. At that point there is no reason for it to be in the class. Also, fix some of the 'const' decorators.
* glsl2: Explicitly walk lists in ir_function::parameter_lists_matchIan Romanick2010-07-192-25/+23
| | | | | | Give ir_function::parameter_lists_match_exist similar treatment. Make the parameters const, and propogate the constness as far as it will trivially go.
* linker: Add comment about bug in initializer handlingIan Romanick2010-07-191-0/+8
|
* linker: First bits of intrastage, intershader function linkingIan Romanick2010-07-194-0/+214
| | | | | | 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.
* ir_function_signature: Make actual_parameters publicIan Romanick2010-07-191-3/+3
|
* linker: Remove some unnecessary includesIan Romanick2010-07-191-2/+0
|
* exec_list: Fix foreach_list_safe.Kenneth Graunke2010-07-192-13/+8
| | | | | | | | It now works correctly when nodes are removed, as it was originally intended to do; it no longer processes nodes added to the list before the current node, nor those added immediately after the current node. This matches the behavior of Linux's list_for_each_safe.
* linker: Use foreach_list_safe in move_non_declarationsIan Romanick2010-07-191-1/+1
| | | | | | 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.
* linker: Move global instructions from the linked shader firstIan Romanick2010-07-191-4/+8
| | | | | | 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.
* glsl2: Fix lexing of octal values, including "0".Eric Anholt2010-07-191-1/+1
| | | | | | | | When faced with a constructor like 'ivec4(0, 2, 0, 0)', we would manage to get a value of 2 instead of 0 for the first "0". Usually 2 characters past "0" would point at some junk and lex as 0 anyway. Fixes glsl-octal and glsl-unused-varyings.
* glsl2: Fix the expression type for atan's pi * sign(y).Eric Anholt2010-07-192-8/+8
| | | | Fixes CorrectFunction.vert.
* glsl2: Add a pass for converting if statements to conditional assignment.Eric Anholt2010-07-193-0/+169
| | | | This will be used on 915 and similar hardware of that generation.
* 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.
* glsl2: Remove the const disease from function signature's callee.Eric Anholt2010-07-185-9/+8
|
* glsl2: Make cross() be an expression operation.Eric Anholt2010-07-185-22/+16
| | | | | | 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
|
* 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).
* glsl2: Remove unnecessary casts of clone return valuesIan Romanick2010-07-132-27/+23
|
* glsl2: Add matrix multiplication to ir_mat_op_to_vec.Eric Anholt2010-07-121-9/+188
|
* 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.
