2010-07-22glsl2: Make ir_assignment derive from ir_instruction, not ir_rvalue.Kenneth Graunke
Assignments can only exist at the top level instruction stream; the residual value is handled by assigning the value to a temporary and returning an ir_dereference_variable of that temporary.
2010-07-21ir_reader: Add support for reading constant arrays.Kenneth Graunke
2010-07-20glsl2: glsl_type has its own talloc context, don't pass one inIan 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'.

2010-07-12linker: Implement first bits of intrastage linkingIan Romanick
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.
2010-07-07ir_reader: Don't emit ir_function multiple times.Kenneth Graunke
2010-07-02glsl2: Fix for dead strings being stored in the symbol table.Kenneth Graunke
2010-06-30glsl2: Use _mesa_glsl_parse_state as the talloc parent, not glsl_shader.Kenneth Graunke
_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.
2010-06-25ir_reader: Free memory for S-Expressions earlier.Kenneth Graunke
There's no point in keeping it around once we've read the IR. Also, remove an unnecessary talloc_parent call.
2010-06-24glsl2: Move the compiler to the subdirectory it will live in in Mesa.Eric Anholt
