* glsl2: Factor out the variable refcounting part of ir_dead_code.cpp.Eric Anholt2010-07-314-112/+190

* glsl2: Fix stack smash when ternary selection is used.Aras Pranckevicius2010-07-311-1/+1

* glsl2: Fix the implementation of atan(y, x).Eric Anholt2010-07-302-166/+166
| | | | | | | | | | | | | | | | So many problems here. One is that we can't do the quadrant handling for all the channels at the same time, so we call the float(y, x) version multiple times. I'd also left out the x == 0 handling. Also, the quadrant handling was broken for y == 0, so there was a funny discontinuity on the +x side if you plugged in obvious values to test. I generated the atan(float y, float x) code from a short segment of GLSL and pasted it in by hand. It would be nice to automate that somehow. Fixes: glsl-fs-atan-1 glsl-fs-atan-2
* ast: Initialize location data in constructor of all ast_node objects.Carl Worth2010-07-301-1/+3
| | | | | | This prevents using uninitialized data in _msea_glsl_error in some cases, (including at least 6 piglit tests). Thanks to valgrind for pointing out the problem!
* ir_to_mesa: Add the function name as a comment to BGNSUB and ENDSUB.Eric Anholt2010-07-301-4/+18
|
* glsl2: Update the callee pointer of calls to newly-linked-in functions.Eric Anholt2010-07-301-0/+2
| | | | | | Otherwise, ir_function_inlining will see the body of the function from the unlinked version of the shader, which won't have had the lowering passes done on it or linking's variable remapping.
* glsl2: Initialize ir_function_signature::is_built_in.Kenneth Graunke2010-07-301-0/+1
| | | | Fixes a valgrind error.
* glcpp: Don't look for backslashes before the beginning of the string.Kenneth Graunke2010-07-301-3/+7
| | | | Fixes a valgrind error.
* glsl2: Do ir_if_return on the way out, not the way in.Eric Anholt2010-07-291-19/+20
| | | | | | | | | | | | | | | The problem with doing it on the way in is that for a function with multiple early returns, we'll move an outer block in, then restart the pass, then move the two inside returns out, then never move outer blocks in again because the remaining early returns are inside an else block and they don't know that there's a return just after their block. By going inside-out, we get the early returns stacked up so that they all move out with a series of move_returns_after_block(). Fixes (on i965): glsl-fs-raytrace-bug27060 glsl-vs-raytrace-bug26691
* glsl2: Make sure functions end with a return before doing ir_if_return.Eric Anholt2010-07-291-1/+61
| | | | | | | | | This catches a few remaining functions that weren't getting inlined, generally operating on global or out variables and using an early return to skip work when possible. Fixes for i965: glsl1-function with early return (3)
* glsl2: Make ir_if_return handle if () { return } else { not return }Eric Anholt2010-07-291-26/+77
| | | | | | | | This makes many remaining functions inlinable. Fixes for i965: glsl1-function with early return (1) glsl1-function with early return (2)
* glsl2: Refactor a bit of ir_if_return for the next changes.Eric Anholt2010-07-291-22/+34
|
* ir_to_mesa: Don't emit a duplicate return at the end of a function.Eric Anholt2010-07-291-2/+6
| | | | It was harmless, but ugly.
* glsl2: Allow use of _mesa_print_ir without a parse state on hand.Eric Anholt2010-07-291-10/+12
|
* ir_constant_variable: Don't mark variable from outside our scope as constant.Eric Anholt2010-07-291-1/+20
| | | | | Fixes (with software, except for alpha): glsl1-function with early return(3)
* glsl2: When dumping IR for debug, indent nested blocks.Eric Anholt2010-07-292-6/+54
| | | | | No more trying to match parens in my head when looking at the body of a short function containing an if statement.
* glsl2: When dumping IR for debug, skip all the empty builtin prototypes.Eric Anholt2010-07-291-3/+15
|
* glsl2: Fix spelling of "sentinel."Eric Anholt2010-07-297-31/+31
|
* glsl2: Fix spelling of "initializer."Eric Anholt2010-07-291-4/+5
|
* glsl2: Remove an inlined unvalued return statement.Eric Anholt2010-07-291-0/+1
| | | | | | | | We already have asserts that it was the last call in the function, so it's safe to remove after it got cloned in. Fixes: glsl-fs-functions-4.
* glsl2: Actually fix glsl-version-define.Eric Anholt2010-07-282-6/+0
|
* glcpp: Add __VERSION__ define to the current language version.Eric Anholt2010-07-285-714/+774
| | | | | | | Fixes: glsl-version-define glsl-version-define-110 glsl-version-define-120
* glcpp: Print integer tokens as decimal, not hex.Eric Anholt2010-07-282-2/+2
|
* glsl2: Make lowp, mediump, highp, and precision identifiers pre-1.20.Eric Anholt2010-07-282-16/+72
| | | | Fixes glsl-precision-110.
* glsl2/Makefile: Append to DEFINES rather than replacing them.Kenneth Graunke2010-07-281-1/+1
| | | | | Otherwise, we lose DEBUG, which causes mtypes.h to set NDEBUG, which causes assertions to not happen, which is no fun for anyone.
* ir_to_mesa: Respect the driver if it rejects a shader.Eric Anholt2010-07-282-9/+11
|
* glsl2: Fix outerProduct builtin.Kenneth Graunke2010-07-283-100/+100
| | | | The type signatures were completely backwards.

|
* ir_constant_expression: Simplify code that implements the "dot" builtin.Kenneth Graunke2010-07-281-1/+1
| | | | There's no need to use an ir_expression; we have a handy C function.
* ir_constant_expression: Add support for the "length" builtin.Kenneth Graunke2010-07-281-1/+1
|
* ir_constant_expression: Extract dot product calculation for reuse.Kenneth Graunke2010-07-281-7/+14
|
* ir_constant_expression: Remove support for dot products of integers.Kenneth Graunke2010-07-281-13/+2
| | | | | This shouldn't be required since dot is only defined for floating point types, even in GLSL 4.0.
