* 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
|
* ir_to_mesa: Add convenience function for opcodes with no src/dst reg.Eric Anholt2010-07-131-20/+21
| | | | Most of flow control is like this.
* 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).
* ir_to_mesa: Add support for variable array indexing of builtin varyings.Eric Anholt2010-07-131-32/+62
| | | | | That is to say, gl_TexCoord[i] now works, fixing glsl-texcoord-array on swrast.
* ir_to_mesa: Add support for array dereferences on the LHS of assignments.Eric Anholt2010-07-131-29/+67
| | | | | | | | | | 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.
* glsl2: Remove unnecessary casts of clone return valuesIan Romanick2010-07-132-27/+23
|
* ir_to_mesa: Rely on ir_mat_op_to_vec for matrix multiplication support.Eric Anholt2010-07-121-83/+5
|
* glsl2: Add matrix multiplication to ir_mat_op_to_vec.Eric Anholt2010-07-121-9/+188
|
* ir_to_mesa: Emit OPCODE_MAD when we find an ADD of a MUL.Eric Anholt2010-07-121-0/+36
| | | | Bug #27914.
* 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.
* linker: Refactor cross_validate_uniforms into cross_validate_globalsIan Romanick2010-07-121-13/+54
| | | | The later, more generic function will be used in the intra-stage linker.
* glsl2: Use a better talloc context for ir_expression_flattening.Eric Anholt2010-07-121-1/+1
| | | | | | The instruction can be hung off of any other in the tree, even if the other one will be deleted, since it'll get stolen to the shader's context later if it's still live.
* glsl2: Add support for variable vector indexing on the LHS of assignments.Eric Anholt2010-07-121-3/+57
| | | | Fixes glsl-vs-vec4-indexing-3.
* glsl2: Fix copy propagation in the presence of derefs in array indexes.Eric Anholt2010-07-121-3/+22
| | | | | | We would clear the in_lhs flag early, avoiding copy propagation on the array index variable (oops) and then copy propagating on the array variable (ouch). Just avoid all copy propagation on the LHS instead.
* ir_to_mesa: Add support for dereferencing matrices from arrays.Eric Anholt2010-07-121-8/+16
|
* ir_validate: Also perform usual checks on ir_dereference_variable nodesIan Romanick2010-07-121-0/+2
|
* ir_validate: Validate that varibles are declared before used in IRIan Romanick2010-07-121-2/+26
|
* linker: Stub-out intrastage linkerIan Romanick2010-07-123-20/+92
|
* Make shader_api.h be C++ friendlyIan Romanick2010-07-121-0/+6
|
* ir_validate: Additional function related invariant checksIan Romanick2010-07-121-0/+60
| | | | | | | | | Add two invariant checks related to functions and function signatures: 1. Ensure that function definitions (ir_function) are not nested. 2. Ensure that the ir_function pointed to by an ir_function_signature is the one that contains it in its signatures list.
* ir_function_signature: Add method to get the function owning a signatureIan Romanick2010-07-122-5/+22
| | | | | | | | | 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.
* glsl2: Add utility function clone_ir_listIan Romanick2010-07-122-0/+69
|
* ir_call: Add method to set the function signature being calledIan Romanick2010-07-122-0/+13
|
* glsl2: Implement ir_function::clone and ir_function_signature::cloneIan Romanick2010-07-121-6/+43
|
* glsl2: Move temp declaration to correct side of if-statement in IRIan Romanick2010-07-121-7/+7
|
* glsl2: Add missing fields in ir_variable::cloneIan Romanick2010-07-121-0/+8
|
* glsl2: Add declarations for temporaries to instruction streamIan Romanick2010-07-121-0/+3
| | | | | | | | Temporary variables added for &&, ||, and ?: were not being added to the instruction stream. This resulted in either test failures or Valgrind being angry after the original IR tree was destroyed by talloc_free. The talloc_free caused the ir_variables to be destroyed even though they were still referenced.
* glsl2: Store the gl_type of the array's element type in the array.Eric Anholt2010-07-121-0/+5
| | | | | Fixes glsl-fs-uniform-array-1, glsl-vs-uniform-array-1, and the -2 tests on software.
* Revert "ir_to_mesa: Add support for adding/subtracting matrices."Eric Anholt2010-07-121-39/+3
| | | | | This reverts commit b4d0c0e0ee983ee614b047799c3e01221a353c98. Now that ir_mat_op_to_vec is landed, this change is no longer needed.
* glsl2: Add a new pass at the IR level to break down matrix ops to vector ops.Eric Anholt2010-07-125-0/+197
| | | | | | | This will be used by the Mesa IR and likely most HW backends, as it allows other optimizations to occur that might not otherwise. Fixes glsl-vs-mat-sub-1, glsl-vs-mat-div-1.
* glsl2: Flatten out expressions that are the child of an assignment rhs.Eric Anholt2010-07-121-7/+19
| | | | | | | This feels a little odd, but it will be useful for ir_mat_to_vec, where I want to see a plain assignment of the expression to a variable, not to a writemasked array dereference with a call as the array index.
* glsl2: Check when inlining a bare function call that it actually is.Eric Anholt2010-07-121-0/+6
| | | | | | | It would be easy to miss an entry either of the two visitors involved that would result in trying to ir->remove() the call to remove it from the instruction stream when really it's part of an expression tree that wasn't flattened.
* ast_function: Fix non-float constructors with matrix arguments.Kenneth Graunke2010-07-091-22/+55
| | | | | | | | | | Previously, code like ivec4(mat2(...)) would fail because the compiler would naively try to convert a mat2 to an imat2...which doesn't exist. Now, a separate pass breaks such matrices down to their columns, which can be converted from vec2 to ivec2. Fixes piglit tests constructor-11.vert, constructor-14.vert, constructor-15.vert, and CorrectConstFolding2.frag.
* ast_function: Move error return earlier and don't indent the world.Kenneth Graunke2010-07-091-142/+139
| | | | This has no functional changes.
* ast_function: Remove unnecessary check for empty constructors.Kenneth Graunke2010-07-091-9/+0
| | | | | This case is already caught by a later check that ensures sufficient components were provided, based on the type.
* glsl2: Use new foreach_list_safe abstraction.Kenneth Graunke2010-07-091-7/+3
|
* glsl2: Add foreach_list_safe which works even when mutating the list.Kenneth Graunke2010-07-091-0/+14
| | | | | | | | In particular, with foreach_list_safe, one can remove and free the current node without crashes; if new nodes are added after the current node, they will be properly visited as well. Signed-off-by: Ian Romanick <[email protected]>
* glsl2: Remove generate_temporary and global temporary counter.Kenneth Graunke2010-07-084-32/+5
| | | | | | | Most places in the code simply use a static name, which works because names are never used to look up an ir_variable. generate_temporary is simply unnecessary (and looks like it would leak memory, and isn't thread safe...)
* mesa: Extend register lifetimes to the end of the largest loop required.Eric Anholt2010-07-071-17/+23
| | | | | | | | | | | | | Previously, a register defined at main scope and used in a loop in a loop could end up getting marked as needed only from the definition outside of the loops to the end of the inner loop, and we would cleverly slot in something else in its register in the end of the outer loop. Fixes glsl-vs-loop-nested and glsl-fs-loop-nested on glsl2. This doesn't happen much on master because the original compiler does its own register allocation, so we find little we can do with linear scan register (re)allocation.
* mesa: Fix documentation of BranchTarget for BRK.Eric Anholt2010-07-071-1/+1
| | | | It was changed in 2009 and the comment wasn't updated.
* glsl2: Add support for gl_PointCoord in 1.20.Eric Anholt2010-07-072-0/+11
| | | | Fixes glsl-fs-pointcoord on swrast (remains broken on 965, like master)
* ir_to_mesa: Fix the assertion on LHS array derefs to DWIM.Eric Anholt2010-07-071-7/+10
| | | | | This allows array derefs of matrices now, which makes idr's GLSL demo happy.
* ir_to_mesa: Add support for constant matrices (untested).Eric Anholt2010-07-071-2/+33
|
* ir_to_mesa: Add support for adding/subtracting matrices.Eric Anholt2010-07-071-3/+39
| | | | This isn't really tested, but didn't break normal vector add/sub.
