2010-09-04ir_reader: Run ir_validate on the generated IR.Kenneth Graunke
It's just too easy to get something wrong in hand-written IR.
2010-09-04ir_reader: Emit global variables at the top of the instruction list.Kenneth Graunke
Since functions are emitted when scanning for prototypes, functions always come first, even if the original IR listed the variable declarations first. Fixes an ir_validate error (to be turned on in the next commit).
2010-09-04ir_reader: Drop support for reading the old assignment format.Kenneth Graunke
2010-09-04glsl: Regenerate autogenerated file builtin_function.cpp.Kenneth Graunke
2010-09-04glsl/builtins: Convert assignments to new format (with write mask).Kenneth Graunke
2010-09-04ir_reader: Read the new assignment format (with write mask).Kenneth Graunke
This preserves the ability to read the old format, for momentary compatibility with all the existing IR implementations of built-ins.
2010-09-04ir_reader: Track the current function and report it in error messages.Kenneth Graunke
2010-09-04glsl/builtins: Actually print the info log if reading a builtin failed.Kenneth Graunke
2010-09-03exec_list: replace class with structBrian Paul
To match the definition below.
2010-09-03glsl2: Use as_constant some places instead of constant_expression_valueIan Romanick
The places where constant_expression_value are still used in loop analysis are places where a new expression tree is created and constant folding won't have happened. This is used, for example, when we try to determine the maximal loop iteration count. Based on review comments by Eric. "...rely on constant folding to have done its job, instead of going all through the subtree again when it wasn't a constant."
2010-09-03glsl2: Allow copy / constant propagation into array indicesIan Romanick
2010-09-03glsl2: Add module to perform simple loop unrollingIan Romanick
2010-09-03glsl2: Track the number of ir_loop_jump instructions that are in a loopIan Romanick
2010-09-03ir_expression: Add static operator_string methodIan Romanick
I've used this in quite a few debug commits that never reached an up-stream tree.
2010-09-03exec_node: Add insert_before that inserts an entire listIan Romanick
2010-09-03glsl2: Eliminate zero-iteration loopsIan Romanick
2010-09-03glsl2: Perform initial bits of loop analysis during compilationIan Romanick
2010-09-03glsl2: Add module to suss out loop control variables from loop analysis dataIan Romanick
This is the next step on the road to loop unrolling
2010-09-03glsl2: Add module to analyze variables used in loopsIan Romanick
This is the first step eventually leading to loop unrolling.
2010-09-03ir_validate: Validate loop control fields in ir_loopIan Romanick
2010-09-03glsl2: Add cmp field to ir_loopIan Romanick
This reprents the type of comparison between the loop induction variable and the loop termination value.
2010-09-03glsl2: Set a flag when visiting the assignee of an assignmentIan Romanick
2010-09-03exec_list: Add pop_headIan Romanick
2010-09-03ir_print_visitor: Print empty else blocks more compactlyIan Romanick
2010-09-02glsl2: Update TODO fileIan Romanick
2010-09-01glsl: Apply implicit conversions to structure constructor parameters.Kenneth Graunke
The code for handling implicit conversions should probably get refactored, but for now, this is easy. Fixes piglit test constructor-26.vert.
2010-09-01glsl: Convert constant record constructor parameters to ir_constants.Kenneth Graunke
I'm not sure if this is strictly necessary, but it seems wise.
2010-09-01glsl: Reject structure constructors that have too many arguments.Kenneth Graunke
Fixes piglit test constructor-27.vert.
2010-09-01glsl2: Remove unnecessary glsl_symbol_table::get_function parameter ↵Ian Romanick
return_constructors Now that constructors are not generated as functions or stored in the symbol table, there is no need to flag whether or not constructors should be returned.
2010-09-01glsl2: Remove unused method glsl_type::generate_constructorIan Romanick
2010-09-01glsl2: Remove unused 'constructor' parameter from glsl_symbol_table::add_typeIan Romanick
2010-09-01glsl2: Don't generate constructor functions for structuresIan Romanick
2010-09-01glsl2: Emit structure constructors inlineIan Romanick
Fixes piglit test cases glsl-[fv]s-all-0[12].
2010-09-01glsl: Fix write mask in matrix-from-matrix constructors.Kenneth Graunke
If the matrix being constructed was larger than the source matrix, it would overwrite the lower-right part of the matrix with the wrong values, rather than leaving it as the identity matrix. For example, constructing a mat4 from a mat2 should only use a writemask of "xy" when copying from the source, but was using "xyzw". Fixes the code generated by piglit test constructor-23.vert.
2010-09-01glsl: Add proper handling for constant matrix-from-matrix constructors.Kenneth Graunke
Fixes piglit test case constructor-21.vert and changes constructor-22.vert to give the correct output.
2010-09-01glsl: Move generate_constructor_(matrix|vector) to ir_constant ctor.Kenneth Graunke
2010-09-01ast_function: Fix check for "too few components".Kenneth Graunke
This was triggering even for matrix-from-matrix constructors. It is perfectly legal to construct a mat3 from a mat2 - the rest will be filled in by the identity matrix. Changes piglit test constructor-23.vert from FAIL to PASS, but the generated code is incorrect.
2010-09-01ast_function: Remove bogus cases from generate_constructor_matrix.Kenneth Graunke
There are no integer matrix types, so switching on them is silly.
2010-09-01glsl: Add forgotten implementations of equal/notEqual on bvecs.Kenneth Graunke
2010-09-01glsl2: Perform algebraic simplifications on logical binary operatorsIan Romanick
Reduces glsl-vs-all-01 from 42 Mesa IR instructions (including the END) to 17.
2010-09-01glsl2: Allow ir_constant::zero to create boolean constantsIan Romanick
2010-09-01glsl2: Disallow function declarations within function definitions in GLSL 1.20Ian Romanick
The GLSL 1.20 spec specifically disallows this, but it was allowed in GLSL 1.10. Fixes piglit test cases local-function-0[13].frag and bugzilla #29921.
2010-08-31glsl2: fix bug in atan(y, x) functionBrian Paul
When x==0, the result was wrong. Fixes piglit glsl-fs-atan-1.shader_test
2010-08-31glsl2: Write vector constructor constants in a single assignmentIan Romanick
Make two passes over the constructor parameters. Write all of the constants in a single write, then write the non-constants one at a time. This causes the fragment shader varying float g; void main() { gl_FragColor = vec4(0.0, g, 0.0, 1.0); } to generate (function main (signature void (parameters ) ( (declare (temporary ) vec4 vec_ctor@0x8580058) (assign (constant bool (1)) (xzw) (var_ref vec_ctor@0x8580058) (constant vec4 (0.000000 0.000000 0.000000 1.000000)) ) (assign (constant bool (1)) (y) (var_ref vec_ctor@0x8580058) (swiz xxxx (var_ref g@0x8580218) )) (assign (constant bool (1)) (xyzw) (var_ref gl_FragColor@0x84d32a0) (var_ref vec_ctor@0x8580058) ) )) ) instead of (function main (signature void (parameters ) ( (declare (temporary ) vec4 vec_ctor@0x8580058) (assign (constant bool (1)) (x) (var_ref vec_ctor@0x8580058) (constant vec4 (0.000000 0.000000 0.000000 1.000000)) ) (assign (constant bool (1)) (y) (var_ref vec_ctor@0x8580058) (swiz xxxx (var_ref g@0x8580218) )) (assign (constant bool (1)) (z) (var_ref vec_ctor@0x8580058) (constant vec4 (0.000000 0.000000 0.000000 1.000000)) ) (assign (constant bool (1)) (w) (var_ref vec_ctor@0x8580058) (constant vec4 (0.000000 0.000000 0.000000 1.000000)) ) (assign (constant bool (1)) (xyzw) (var_ref gl_FragColor@0x84d32a0) (var_ref vec_ctor@0x8580058) ) )) ) A similar optimization could be done for matrix constructors, but it is a little more complicate there.
2010-08-31ast_to_hir: Add support for bit-wise operators (but not shifts).Kenneth Graunke
Previously, using bit-wise operators in some larger expression would crash on a NULL pointer dereference. This code at least doesn't crash. Fixes piglit test bitwise-01.frag.
2010-08-30linker: Require an exact matching signature when looking for prototypes.Kenneth Graunke
Fixes piglit test glsl-override-builtin. The linker incorrectly found the prototype for the float signature, rather than adding a new prototype with the int return type. This caused ir_calls with type int to have their callees set to the float signature, triggering an assert.
2010-08-30linker: Handle varying arrays, matrices, and arrays of matricesIan Romanick
Fixes piglit test case glsl-array-varying-01.
2010-08-30glsl: Clear the static values of builtin function profiles at release.Eric Anholt
When releasing the builtin functions, we were just freeing the memory, not telling the builtin function loader that we had freed its memory. I wish I had done ARB_ES2_compatibility so we had regression testing of this path. Fixes segfault on changing video options in nexuiz.
2010-08-30glsl2: Commit generated files changed by previous commitIan Romanick
2010-08-30glsl2: Parse #pragma linesIan Romanick
All pragmas are currently ignored. Also, the error messages when a pragma is used incorrectly (i.e., '#pragma debug(on)' inside a function) are crap, but I think this is sufficient for now. Fixes piglit test cases pragma-0[1-8].(vert|frag).
