2010-07-21glsl2: Extend ir_constant to store constant arrays, and generate them.Kenneth Graunke
Since GLSL permits arrays of structures, we need to store each element as an ir_constant*, not just ir_constant_data. Fixes parser tests const-array-01.frag, const-array-03.frag, const-array-04.frag, const-array-05.frag, though 03 and 04 generate the wrong code.
2010-07-20glsl2: Implement utility routine to talloc reparent an IR treeIan Romanick
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'.
2010-07-20glsl2: strdup the field names used in dereference_record.Eric Anholt
Otherwise, after linking and freeing the old data, the pointer would dangle. Partial fix for glsl1-struct*.
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.

2010-07-18glsl2: 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.
2010-07-12ir_function_signature: Add method to get the function owning a signatureIan Romanick
There is no setter function, the getter returns a constant pointer, and ir_function_signature::_function is private for a reason. The only way to make a connection between a function and function signature is via ir_function::add_signature. This helps ensure that certain invariants (i.e., a function signature is in the list of signatures for its _function) are met.
2010-07-12ir_call: Add method to set the function signature being calledIan Romanick
2010-07-01glsl2: Add ir_unop_fract as an expression type.Eric Anholt
Most backends will prefer seeing this to seeing (a - floor(a)), so represent it explicitly.
2010-06-30glsl2: Make function names and variable names be children of the node.Eric Anholt
This avoids losing their memory when the parser state is freed.
2010-06-29ir_swizzle: Add new constructor, refactor constructorsIan Romanick
Adds a new constructor that takes an array of component values. Refactors the meat of the two constructors to an init_mask method.
2010-06-24glsl2: Move the compiler to the subdirectory it will live in in Mesa.Eric Anholt
