2010-07-19linker: look up function signatures during linking instead of using calleeIan Romanick
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.
2010-07-19linker: Pull find_matching_signature out of call_link_visitorIan Romanick
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.
2010-07-19glsl2: Explicitly walk lists in ir_function::parameter_lists_matchIan Romanick
Give ir_function::parameter_lists_match_exist similar treatment. Make the parameters const, and propogate the constness as far as it will trivially go.
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.
2010-07-19ir_function_signature: Make actual_parameters publicIan Romanick
2010-07-19linker: Remove some unnecessary includesIan Romanick
2010-07-19exec_list: Fix foreach_list_safe.Kenneth Graunke
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.
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.
2010-07-19glsl2: Fix lexing of octal values, including "0".Eric Anholt
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.
2010-07-19glsl2: Fix the expression type for atan's pi * sign(y).Eric Anholt
Fixes CorrectFunction.vert.
2010-07-19i915: Ask the compiler to flatten out all the if statements that it can.Eric Anholt
2010-07-19glsl2: Add a pass for converting if statements to conditional assignment.Eric Anholt
This will be used on 915 and similar hardware of that generation.
2010-07-19glsl2: Give IR nodes a type field.Eric Anholt
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.
2010-07-19ir_to_mesa: Do validation on the IR tree.Eric Anholt
2010-07-19ir_to_mesa: Don't do lowering passes on an errored-out shader.Eric Anholt
2010-07-18ir_to_mesa: Rename struct temp_entry, which is used for all variables now.Eric Anholt
2010-07-18ir_to_mesa: Add support for function calls.Eric Anholt
Unlike the previous compiler, in this case we emit only one copy of the function regardless of how many times it's called.
2010-07-18glsl2: Remove the const disease from function signature's callee.Eric Anholt
2010-07-18glsl2: Make cross() be an expression operation.Eric Anholt
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.
2010-07-18glsl2: Fix warning from always-false assert not being known to not return.Eric Anholt

2010-07-14glsl2/builtins: Rework clamp to use scalar/vector combinations.Kenneth Graunke

2010-07-14ir_constant_expression: Add support for ir_binop_min and ir_binop_max.Kenneth Graunke
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))
2010-07-14ir_constant_expression: Add support for ir_binop_pow.Kenneth Graunke

2010-07-14ir_constant_expression: Add support for ir_unop_trunc.Kenneth Graunke
This uses a C99 function.
2010-07-14ir_constant_expression: Add support for ir_unop_log2.Kenneth Graunke
This uses a C99 function.
2010-07-14ir_constant_expression: Add support for ir_unop_exp2.Kenneth Graunke
This uses a C99 function.
2010-07-14ir_constant_expression: Add support for ir_unop_sign.Kenneth Graunke
2010-07-14ir_constant_expression: Remove bogus assert in ir_unop_abs case.Kenneth Graunke
abs is defined for integral types; it's even implemented.
2010-07-14glsl2: Remove ir_program bong hits.Kenneth Graunke
2010-07-13ir_to_mesa: Add convenience function for opcodes with no src/dst reg.Eric Anholt
Most of flow control is like this.
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).
2010-07-13ir_to_mesa: Add support for variable array indexing of builtin varyings.Eric Anholt
That is to say, gl_TexCoord[i] now works, fixing glsl-texcoord-array on swrast.
2010-07-13ir_to_mesa: Add support for array dereferences on the LHS of assignments.Eric Anholt
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.
2010-07-13glsl2: Remove unnecessary casts of clone return valuesIan Romanick
2010-07-12ir_to_mesa: Rely on ir_mat_op_to_vec for matrix multiplication support.Eric Anholt

2010-07-12ir_to_mesa: Emit OPCODE_MAD when we find an ADD of a MUL.Eric Anholt
Bug #27914.
