2011-02-08glsl: Disable the new copy propagation pass until it gets fixed.Eric Anholt
It apparently regressed a bunch of ES2 cases.
2011-02-08glsl: Set operators '%' and '%=' to be reserved when GLSL < 1.30Chad Versace
From section 5.9 of the GLSL 1.20 spec: The operator modulus (%) is reserved for future use. From section 5.8 of the GLSL 1.20 spec: The assignments modulus into (%=), left shift by (<<=), right shift by (>>=), inclusive or into ( |=), and exclusive or into ( ^=). These operators are reserved for future use. The GLSL ES 1.00 spec and GLSL 1.10 spec have similiar language. Fixes bug: https://bugs.freedesktop.org//show_bug.cgi?id=33916 Fixes Piglit tests: spec/glsl-1.00/compiler/arithmetic-operators/modulus-00.frag spec/glsl-1.00/compiler/assignment-operators/modulus-assign-00.frag spec/glsl-1.10/compiler/arithmetic-operators/modulus-00.frag spec/glsl-1.10/compiler/assignment-operators/modulus-assign-00.frag spec/glsl-1.20/compiler/arithmetic-operators/modulus-00.frag spec/glsl-1.20/compiler/assignment-operators/modulus-assign-00.frag
2011-02-04linker: Generate link errors when ES shaders are missing stagesIan Romanick
ES requires that a vertex shader and a fragment shader be present. Fixes bugzilla #32214.
2011-02-04glsl: Add opt_copy_propagation_elements.cpp to SConscript.Vinson Lee
Fixes SCons build.
2011-02-04glsl: Remove extra checks for constant true assignment conditions.Eric Anholt
These are already stripped by opt_constant_folding.cpp.
2011-02-04glsl: Fix a comment typo in copy propagation.Eric Anholt
2011-02-04glsl: Add a new opt_copy_propagation variant that does it channel-wise.Eric Anholt
This patch cleans up many of the extra copies in GLSL IR introduced by i965's scalarizing passes. It doesn't result in a statistically significant performance difference on nexuiz high settings (n=3) or my demo (n=10), due to brw_fs.cpp's register coalescing covering most of those extra moves anyway. However, it does make the debug of wine's GLSL shaders much more tractable, and reduces instruction count of glsl-fs-convolution-2 from 376 to 288.
2011-02-03ralloc: Add missing va_end following va_copy.Vinson Lee
2011-02-03glsl: Add using statements for standard library functions.Vinson Lee
Standard library functions in C++ are in the std namespace. When using C++-style header files for the standard library, some compilers, such as Sun Studio, provide symbols only for the std namespace and not for the global namespace. This patch adds using statements for standard library functions. Another option could have been to prepend standard library function calls with 'std::'. This patch fixes several compilation errors with Sun Studio.
2011-02-02glcpp: Raise error when modulus is zeroChad Versace
For example, this now raises an error: #define XXX 1 / 0 Fixes bug: https://bugs.freedesktop.org//show_bug.cgi?id=33507 Fixes Piglit test: spec/glsl-1.10/preprocessor/modulus-by-zero.vert NOTE: This is a candidate for the 7.9 and 7.10 branches.
2011-02-02glsl: Avoid division-by-zero during constant-foldingChad Versace
Avoid division-by-zero when constant-folding the following expression types: ir_unop_rsq ir_binop_div ir_binop_mod Fixes bugs: https://bugs.freedesktop.org//show_bug.cgi?id=33306 https://bugs.freedesktop.org//show_bug.cgi?id=33508 Fixes Piglit tests: glslparsertest/glsl2/div-by-zero-01.frag glslparsertest/glsl2/div-by-zero-02.frag glslparsertest/glsl2/div-by-zero-03.frag glslparsertest/glsl2/modulus-zero-01.frag glslparsertest/glsl2/modulus-zero-02.frag NOTE: This is a candidate for the 7.9 and 7.10 branches.
2011-02-02glsl: Fix constant-folding for reciprocal expressionsChad Versace
Do not constant-fold a reciprocal if any component of the reciprocated expression is 0. For example, do not constant-fold `1 / vec4(0, 1, 2, 3)`. Incorrect, previous behavior ---------------------------- Reciprocals were constant-folded even when some component of the reciprocated expression was 0. The incorrectly applied arithmetic was: 1 / 0 := 0 For example, 1 / vec4(0, 1, 2, 3) = vec4(0, 1, 1/2, 1/3) NOTE: This is a candidate for the 7.9 and 7.10 branches.
2011-02-01glsl: Fix use of uninitialized values in _mesa_glsl_parse_state ctor.Kenneth Graunke
This has probably existed since e5e34ab18eeaffa465 or so. NOTE: This is a candidate for the 7.9 and 7.10 branches.
2011-02-01glsl: Fix invalid use of ralloc_asprintf in prototype_string.Kenneth Graunke
This was my mistake when converting from talloc to ralloc. I was confused because the other calls in the function are to asprintf_append and the original code used str as the context rather than NULL. Fixes bug #33823.
2011-02-01glsl: Fix printf_length() on MSVC.José Fonseca
2011-02-01glsl: Fix memory error when creating the supported version string.Kenneth Graunke
Passing ralloc_vasprintf_append a 0-byte allocation doesn't work. If passed a non-NULL argument, ralloc calls strlen to find the end of the string. Since there's no terminating '\0', it runs off the end. Fixes a crash introduced in 14880a510a1a288df0778395097d5a52806abfb0.
2011-01-31texture_builtins.py: Fix a warning about mixed tabs/spaces.Kenneth Graunke
2011-01-31glsl: Refresh autogenerated lexer and parser files.Ian Romanick
For the previous commit.
2011-01-31glsl: Reject shader versions not supported by the implementationIan Romanick
Previously we'd happily compile GLSL 1.30 shaders on any driver. We'd also happily compile GLSL 1.10 and 1.20 shaders in an ES2 context. This has been a long standing FINISHME in the compiler. NOTE: This is a candidate for the 7.9 and 7.10 branches
2011-01-31glsl: Ensure that all GLSL versions are supported in the stand-alone compilerIan Romanick
NOTE: This is a candidate for the 7.9 and 7.10 branches
2011-01-31glsl: Fix dependencies / linkage for glsl_compilerIan Romanick
2011-01-31glsl: regerated filesBrian Paul
2011-01-31glsl: make _token_list_is_empty_ignoring_space() staticBrian Paul
To silence warning about missing prototype.
2011-01-31scons/glsl: add top-level 'include' dir to CPPPATHBrian Paul
To avoid using the /usr/include/GL/gl.h file which may be lacking some special #defines.
2011-01-31glsl: add cast to silence signed/unsigned comparison warningBrian Paul
2011-01-31glsl: Define va_copy on MSVC.José Fonseca
2011-01-31glsl/builtins: Uncomment prototypes for texture*Offset functions.Kenneth Graunke
2011-01-31texture_builtins.py: Generate texture*Offset functions.Kenneth Graunke
2011-01-31texture_builtins.py: Generalize the "use_proj" field to support offsets.Kenneth Graunke
Rather than passing "True", pass a bitfield describing the particular variant's features - either projection or offset. This should make the code a bit more readable ("Proj" instead of "True") and make it easier to support offsets in the future.
2011-01-31texture_builtins.py: Refactor coordinate dimension calculations.Kenneth Graunke
For offsets, we'll want the straight sampler dimensionality, without the +1 for array types. Create a new function to do that; refactor.
2011-01-31glsl: Introduce a new "const_in" variable mode.Kenneth Graunke
This annotation is for an "in" function parameter for which it is only legal to pass constant expressions. The only known example of this, currently, is the textureOffset functions. This should never be used for globals.
2011-01-31glsl: Change texel offsets to a single vector rvalue.Kenneth Graunke
Having these as actual integer values makes it difficult to implement the texture*Offset built-in functions, since the offset is actually a function parameter (which doesn't have a constant value). The original rationale was that some hardware needs these offset baked into the instruction opcode. However, at least i965 should be able to support non-constant offsets. Others should be able to rely on inlining and constant propagation.
2011-01-31glsl: Re-synchronize ir_variable_mode and the printer's string array.Kenneth Graunke
Since the introduction of ir_var_system_value, system variables would be printed as "temporary" and temporaries would result in out-of-bounds array access, showing up as garbage in printed IR.

2011-01-29Revert "glcpp: Demote "macro redefined" from an error to a warning"Carl Worth
This reverts commit d3df641f0aba99b0b65ecd4d9b06798bca090a29. The original commit had sat unpushed on my machine for months. By the time I found it again, I had forgotten that we had decided not to use this change after all, (the relevant test was removed long ago).
2011-01-28glcpp: Demote "macro redefined" from an error to a warningCarl Worth
The GLSL specification is vague here, (just says "as is standard for C++"), though the C specifications seem quite clear that this should be an error. However, an existing piglit test (CorrectPreprocess11.frag) expects this to be a warning, not an error, so we change this, and document in README the deviation from the specification.
2011-01-26glsl: Refresh autogenerated lexer fileChad Versace
For previous commit.
2011-01-26glsl: Remove extraneously extraneous parensChad Versace
I found this parenthetical usage of parentheses to be extraneously extraneous: (yyextra->ARB_fragment_coord_conventions_enable)
2011-01-26glsl: Enable AMD_conservative_depth in parserChad Versace
All the necessary compiler infrastructure for AMD_conservative_depth is in place, so it's safe to enable it in the parser.
2011-01-26glsl: Raise linking error if gl_FragDepth layout is inconsistentChad Versace
From the AMD_conservative_depth spec: If gl_FragDepth is redeclared in any fragment shader in a program, it must be redeclared in all fragment shaders in that program that have static assignments to gl_FragDepth. All redeclarations of gl_FragDepth in all fragment shaders in a single program must have the same set of qualifiers.
2011-01-26glsl: Propagate depth layout qualifier from AST to IRChad Versace
2011-01-26glsl: Define enum ir_depth_layoutChad Versace
2011-01-26glsl: Refresh autogenerated parser filesChad Versace
For commits titled: glcpp: Conditionally define macro GL_AMD_conservative_depth glsl: Add support for AMD_conservative_depth to parser
2011-01-26glsl: Add support for AMD_conservative_depth to parserChad Versace
When AMD_conservative_depth is enabled: * Let 'layout' be a token. * Extend the production rule of layout_qualifier_id to process the tokens: depth_any depth_greater depth_less depth_unchanged
2011-01-26glsl: Add depth layout qualifiers to ast_type_qualifierChad Versace
2011-01-26glcpp: Conditionally define macro GL_AMD_conservative_depthChad Versace
Define macro GL_AMD_conservative_depth to 1 when its extension is enabled.
