* glsl2: Add a pass to strip out noop swizzles.Eric Anholt2010-08-131-0/+1
| | | | | | With the glsl2-965 branch, the optimization of glsl-algebraic-rcp-rcp regressed due to noop swizzles hiding information from ir_algebraic. This cleans up those noop swizzles for us.
* glsl2: Add a generic visitor class to call back with pointers to each rvalue.Eric Anholt2010-08-131-0/+1
| | | | | I keep copy and pasting this code all over, so consolidate it in one place.
* glsl2: Use --nounistd to fix MSVC buildIan Romanick2010-08-131-2/+2
| | | | | Also remove the --never-interactive command line option for the preprocessor lexer. This was already done for main compiler lexer.
* glsl2: Change command line options passed to flexIan Romanick2010-08-111-1/+1
| | | | | | | | | Remove --never-interactive because it is already specified in the source using %option. Use -o instead of --outfile. Some of the %option commands may also need to be removed for compatibility with older versions (e.g., 2.5.4) of flex. This should fix bugzilla #29209.
* glsl2: Use bison command line option to set prefixIan Romanick2010-08-111-1/+1
| | | | | | Bison version 2.3 doesn't seem to support %name-prefix in the source. This should fix bugzilla #29207.
* glsl2: Add a pass to transform ir_binop_sub to add(op0, neg(op1))Eric Anholt2010-08-091-0/+1
| | | | | | All the current HW backends transform subtract to adding the negation, so I haven't bothered peepholing it back out in Mesa IR. This allows some subtract of subtract to get removed in ir_algebraic.
* glsl2: Add constant propagation.Eric Anholt2010-08-091-0/+1
| | | | | | | | Whereas constant folding evaluates constant expressions at rvalue nodes, constant propagation tracks constant components of vectors across execution to replace (possibly swizzled) variable dereferences with constant values, triggering possible constant folding or reduced variable liveness.
* glsl2: Move gl_program->InputsRead/OutputsWritten setting to an ir pass.Eric Anholt2010-08-061-0/+1
| | | | | | | This lets us handle arrays much better than trying to work backwards from assembly. Fixes fbo-drawbuffers-maxtargets on swrast (i965 needs loop unrolling)
* glsl2: Add a pass to convert exp and log to exp2 and log2.Eric Anholt2010-08-051-0/+1
| | | | | | | | | Fixes ir_to_mesa handling of unop_log, which used the weird ARB_vp LOG opcode that doesn't do what we want. This also lets the multiplication coefficients in there get constant-folded, possibly. Fixes: glsl-fs-log
* ir_structure_splitting: New pass to chop structures into their components.Eric Anholt2010-08-051-0/+1
| | | | | | | This doesn't do anything if your structure goes through an uninlined function call or if whole-structure assignment occurs. As such, the impact is limited, at least until we do some global copy propagation to reduce whole-structure assignment.
* glsl2: Add a pass for removing unused functions.Eric Anholt2010-08-051-0/+1
| | | | | | | | | For a shader involving many small functions, this avoids running optimization across all of them after they've been inlined post-linking. Reduces the runtime of linking and running a fragment shader from Yo Frankie from 1.6 seconds to 0.9 seconds (-44.9%, +/- 3.3%).
* glcpp: Remove xtalloc wrappers in favor of plain talloc.Kenneth Graunke2010-08-041-2/+1
| | | | | | Calling exit() on a memory failure probably made sense for the standalone preprocessor, but doesn't seem too appealing as part of the GL library. Also, we don't use it in the main compiler.
* glsl2: Don't add mesa/program/ as an include dir. Let includes say program/.Eric Anholt2010-08-021-1/+0
|
* glsl2: Add new tree grafting optimization pass.Eric Anholt2010-07-311-0/+1
|
* glsl2: Factor out the variable refcounting part of ir_dead_code.cpp.Eric Anholt2010-07-311-0/+1
|
* 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.
* glsl2: Add optimization pass for algebraic simplifications.Eric Anholt2010-07-271-0/+1
| | | | | | This cleans up the assembly output of almost all the non-logic tests glsl-algebraic-*. glsl-algebraic-pow-two needs love (basically, flattening to a temporary and squaring it).
* Merge remote branch 'origin/master' into glsl2Eric Anholt2010-07-261-4/+4
|\ | | | | | | | | | | | | | | | | | | | | This pulls in multiple i965 driver fixes which will help ensure better testing coverage during development, and also gets past the conflicts of the src/mesa/shader -> src/mesa/program move. Conflicts: src/mesa/Makefile src/mesa/main/shaderapi.c src/mesa/main/shaderobj.h
* | glsl2: Add the API defines to the glsl2 build so we get the right GLcontextEric Anholt2010-07-221-2/+6
| | | | | | | | | | | | | | Fixes: draw_buffers-08.frag draw_buffers-09.frag glsl-vs-texturematrix-2
* | glsl2: Add function to import function prototypes from one IR tree to anotherIan Romanick2010-07-211-0/+1
| |
* | glsl2: Add a constructor for _mesa_glsl_parse_stateIan Romanick2010-07-201-0/+1
| | | | | | | | Coming changes to the handling of built-in functions necessitate this.
* | Build a standalone glcpp binary.Carl Worth2010-07-201-3/+17
| | | | | | | | | | This is convenient for testing the preprocessor independent of the rest of mesa, (just run glcpp-test in the src/glsl/glcpp/tests).
* | linker: First bits of intrastage, intershader function linkingIan Romanick2010-07-191-0/+1
| | | | | | | | | | | | This handles the easy case of linking a function in a different compilation unit that doesn't call any functions or reference any global variables.
* | glsl2: Add a pass for converting if statements to conditional assignment.Eric Anholt2010-07-191-0/+1
| | | | | | | | This will be used on 915 and similar hardware of that generation.
* | glsl2: Add a new pass at the IR level to break down matrix ops to vector ops.Eric Anholt2010-07-121-0/+1
| | | | | | | | | | | | | | 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: Add a pass to simplify if statements returning from both sides.Eric Anholt2010-07-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows function inlining making the following tests work even without function calls implemented: glsl-fs-functions-2 glsl-fs-functions-3 glsl-vs-functions glsl-vs-functions-2 glsl-vs-functions-3 glsl-vs-vec4-indexing-5 (Note that those tests were designed to trigger actual function calls, and this defeats them. However, those testcases ended up catching the bug in the previous commit.)
* | glsl2: Add pass for supporting variable vector indexing in rvalues.Eric Anholt2010-07-061-0/+1
| | | | | | | | | | | | | | The Mesa IR needs this to support vector indexing correctly, and hardware backends such as 915 would want this behavior as well. Fixes glsl-vs-vec4-indexing-2.
* | glsl2: Add a pass to break ir_binop_div to _mul and _rcp.Eric Anholt2010-07-021-0/+1
| | | | | | | | This results in constant folding of a constant divisor.
* | glsl2: Add a pass to convert mod(a, b) to b * fract(a/b).Eric Anholt2010-07-011-0/+1
| | | | | | | | This is used by the Mesa IR backend to implement mod, fixing glsl-fs-mod.
* | glsl2: Fix dependencies. (at least partially)Eric Anholt2010-06-251-2/+7

* | glsl2: Replace the GLSL compiler with the glsl2 project.Eric Anholt2010-06-241-8/+122

Still don't know how to add glsl to mesa dependencies.
