* linker: Generate link errors when ES shaders are missing stagesIan Romanick2011-02-041-0/+14
| | | | | | ES requires that a vertex shader and a fragment shader be present. Fixes bugzilla #32214.
* glsl: Add opt_copy_propagation_elements.cpp to SConscript.Vinson Lee2011-02-041-0/+1
| | | | Fixes SCons build.
* glsl: Remove extra checks for constant true assignment conditions.Eric Anholt2011-02-045-28/+9
| | | | These are already stripped by opt_constant_folding.cpp.
* glsl: Fix a comment typo in copy propagation.Eric Anholt2011-02-041-1/+1
|
* glsl: Add a new opt_copy_propagation variant that does it channel-wise.Eric Anholt2011-02-044-0/+464
| | | | | | | | | | 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.
* ralloc: Add missing va_end following va_copy.Vinson Lee2011-02-031-0/+2
|
* glsl: Add using statements for standard library functions.Vinson Lee2011-02-0314-0/+33
| | | | | | | | | | | | | 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.
* glcpp: Raise error when modulus is zeroChad Versace2011-02-021-1/+6
| | | | | | | | | | 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.
* glsl: Avoid division-by-zero during constant-foldingChad Versace2011-02-021-1/+19
| | | | | | | | | | | | | | | | | | | | | 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.
* glsl: Fix constant-folding for reciprocal expressionsChad Versace2011-02-021-6/+10
| | | | | | | | | | | | | | | 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.
* glsl: Fix use of uninitialized values in _mesa_glsl_parse_state ctor.Kenneth Graunke2011-02-011-0/+2
| | | | | | This has probably existed since e5e34ab18eeaffa465 or so. NOTE: This is a candidate for the 7.9 and 7.10 branches.
* glsl: Fix invalid use of ralloc_asprintf in prototype_string.Kenneth Graunke2011-02-011-1/+1
| | | | | | | | 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.
* glsl: Fix printf_length() on MSVC.José Fonseca2011-02-011-0/+8
|
* glsl: Fix memory error when creating the supported version string.Kenneth Graunke2011-02-011-1/+1
| | | | | | | | 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.
* texture_builtins.py: Fix a warning about mixed tabs/spaces.Kenneth Graunke2011-01-311-1/+1
|
* glsl: Refresh autogenerated lexer and parser files.Ian Romanick2011-01-311-256/+271
| | | | For the previous commit.
* glsl: Reject shader versions not supported by the implementationIan Romanick2011-01-313-9/+82
| | | | | | | | 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
* glsl: Ensure that all GLSL versions are supported in the stand-alone compilerIan Romanick2011-01-311-0/+6
| | | | NOTE: This is a candidate for the 7.9 and 7.10 branches
* glsl: Fix dependencies / linkage for glsl_compilerIan Romanick2011-01-311-2/+2
|
* glsl: regerated filesBrian Paul2011-01-312-125/+118
|
* glsl: make _token_list_is_empty_ignoring_space() staticBrian Paul2011-01-311-1/+1
| | | | To silence warning about missing prototype.
* scons/glsl: add top-level 'include' dir to CPPPATHBrian Paul2011-01-311-0/+1
| | | | | To avoid using the /usr/include/GL/gl.h file which may be lacking some special #defines.
* glsl: add cast to silence signed/unsigned comparison warningBrian Paul2011-01-311-1/+1
|
* glsl: Define va_copy on MSVC.José Fonseca2011-01-311-0/+8

* glsl/builtins: Uncomment prototypes for texture*Offset functions.Kenneth Graunke2011-01-312-20/+0
|
* texture_builtins.py: Generate texture*Offset functions.Kenneth Graunke2011-01-311-5/+80
|
* texture_builtins.py: Generalize the "use_proj" field to support offsets.Kenneth Graunke2011-01-311-52/+57
| | | | | | | | 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.
* texture_builtins.py: Refactor coordinate dimension calculations.Kenneth Graunke2011-01-311-5/+9
| | | | | For offsets, we'll want the straight sampler dimensionality, without the +1 for array types. Create a new function to do that; refactor.
* glsl: Introduce a new "const_in" variable mode.Kenneth Graunke2011-01-3112-4/+36
| | | | | | | | 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.
* glsl: Change texel offsets to a single vector rvalue.Kenneth Graunke2011-01-318-29/+42
| | | | | | | | | | | 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.
* glsl: Re-synchronize ir_variable_mode and the printer's string array.Kenneth Graunke2011-01-311-1/+1
| | | | | | 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.

* Remove talloc from the make and automake build systems.Kenneth Graunke2011-01-311-4/+2

* Revert "glcpp: Demote "macro redefined" from an error to a warning"Carl Worth2011-01-294-38/+15
| | | | | | | | 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).
* glcpp: Demote "macro redefined" from an error to a warningCarl Worth2011-01-284-15/+38
| | | | | | | | | | 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.
* glsl: Refresh autogenerated lexer fileChad Versace2011-01-261-117/+118
| | | | For previous commit.
* glsl: Remove extraneously extraneous parensChad Versace2011-01-261-1/+1
| | | | | | I found this parenthetical usage of parentheses to be extraneously extraneous: (yyextra->ARB_fragment_coord_conventions_enable)
* glsl: Enable AMD_conservative_depth in parserChad Versace2011-01-261-0/+7
| | | | | All the necessary compiler infrastructure for AMD_conservative_depth is in place, so it's safe to enable it in the parser.
* glsl: Raise linking error if gl_FragDepth layout is inconsistentChad Versace2011-01-261-0/+26
| | | | | | | | | 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.
* glsl: Propagate depth layout qualifier from AST to IRChad Versace2011-01-263-0/+73
|
* glsl: Define enum ir_depth_layoutChad Versace2011-01-262-0/+35
|
* glsl: Refresh autogenerated parser filesChad Versace2011-01-263-165/+180
| | | | | | For commits titled: glcpp: Conditionally define macro GL_AMD_conservative_depth glsl: Add support for AMD_conservative_depth to parser
* glsl: Add support for AMD_conservative_depth to parserChad Versace2011-01-263-8/+34
| | | | | | | | | | 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
* glsl: Add depth layout qualifiers to ast_type_qualifierChad Versace2011-01-261-0/+8
|
* glcpp: Conditionally define macro GL_AMD_conservative_depthChad Versace2011-01-261-0/+2
| | | | | Define macro GL_AMD_conservative_depth to 1 when its extension is enabled.
* linker: Propagate max_array_access while linking functionsIan Romanick2011-01-252-4/+13
| | | | | | | | | Update the max_array_access of a global as functions that use that global are pulled into the linked shader. Fixes piglit test glsl-fs-implicit-array-size-01 and bugzilla #33219. NOTE: This is a candidate for the 7.9 and 7.10 branches.
* linker: Set sizes for non-global arrays as wellIan Romanick2011-01-251-18/+17
| | | | | | | | | Previously only global arrays with implicit sizes would be patched. This causes all arrays that are actually accessed to be sized. Fixes piglit test glsl-fs-implicit-array-size-02. NOTE: This is a candidate for the 7.9 and 7.10 branches.
