* glsl2: Add new ir_constant::zero static method.Kenneth Graunke2010-07-281-0/+12
| | | | This conveniently creates a zero value of whatever type you want.
* glsl2: When stealing var->constant_value, steal its children as well.Eric Anholt2010-07-271-1/+1
| | | | | Fixes: glsl1-GLSL 1.20 uniform array constructor
* glsl2: Also steal the constant components of aggregate-typed ir_constants.Eric Anholt2010-07-261-0/+18
|
* glsl2: Steal ir_variable's constant_value field.Kenneth Graunke2010-07-261-0/+3
| | | | Fixes a link-time crash in glsl-vs-cross-3.
* glsl2: Initialize ir_instruction::type and ir_rvalue::type.Kenneth Graunke2010-07-221-0/+5
| | | | | | | | | | | Top-level instructions now get NULL as their default type (since type is irrelevant for things like ir_function), while ir_rvalues get error_type by default. This should make it easier to tell if we've forgotten to set a type. It also fixes some "Conditional jump or move depends on uninitialized value" errors in valgrind caused by ir_validate examining the type of top level ir_instructions, which weren't set.
* ir_constant_expression: Add support for array == and !=.Kenneth Graunke2010-07-211-3/+8
| | | | | Piglit parser tests const-array-03.frag and const-array-04.frag now generate the correct code.
* glsl2: Extend ir_constant to store constant arrays, and generate them.Kenneth Graunke2010-07-211-2/+21
| | | | | | | | | 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.
* glsl2: Implement utility routine to talloc reparent an IR treeIan Romanick2010-07-201-0/+15
|
* glsl2: Add and use new variable mode ir_var_temporaryIan Romanick2010-07-201-2/+4
| | | | | | | | | | | | | | | | | 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'.
* glsl2: strdup the field names used in dereference_record.Eric Anholt2010-07-201-2/+2
| | | | | Otherwise, after linking and freeing the old data, the pointer would dangle. Partial fix for glsl1-struct*.
* glsl2: Give IR nodes a type field.Eric Anholt2010-07-191-2/+21
| | | | | | | 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 Anholt2010-07-181-1/+1
|
* glsl2: Make cross() be an expression operation.Eric Anholt2010-07-181-0/+2
| | | | | | 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.
* ir_function_signature: Add method to get the function owning a signatureIan Romanick2010-07-121-1/+1
| | | | | | | | | 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.
* ir_call: Add method to set the function signature being calledIan Romanick2010-07-121-0/+8
|
* glsl2: Add ir_unop_fract as an expression type.Eric Anholt2010-07-011-0/+2
| | | | | Most backends will prefer seeing this to seeing (a - floor(a)), so represent it explicitly.
* glsl2: Make function names and variable names be children of the node.Eric Anholt2010-06-301-3/+2
| | | | This avoids losing their memory when the parser state is freed.
* ir_swizzle: Add new constructor, refactor constructorsIan Romanick2010-06-291-18/+45
| | | | | Adds a new constructor that takes an array of component values. Refactors the meat of the two constructors to an init_mask method.
* glsl2: Move the compiler to the subdirectory it will live in in Mesa.Eric Anholt2010-06-241-0/+818
