2011-03-04glsl: Process redeclarations before initializersIan Romanick
If an array redeclaration includes an initializer, the initializer would previously be dropped on the floor. Instead, directly apply the initializer to the correct ir_variable instance and append the generated instructions. Fixes bugzilla #34374 and piglit tests glsl-{vs,fs}-array-redeclaration. NOTE: This is a candidate for stable release branches. 0292ffb8 and 8e6cb9fe are also necessary.

These are now unnecessary.
2011-03-03glcpp: Rework lexer to use a SKIP state rather than REJECT.Kenneth Graunke
Previously, the rule deleted by this commit was matched every single time (being the longest match). If not skipping, it used REJECT to continue on to the actual correct rule. The flex manual advises against using REJECT where possible, as it is one of the most expensive lexer features. So using it on every match seems undesirable. Perhaps more importantly, it made it necessary for the #if directive rules to contain a look-ahead pattern to make them as long as the (now deleted) "skip the whole line" rule. This patch introduces an exclusive start state, SKIP, to avoid REJECTs. Each time the lexer is called, the code at the top of the rules section will run, implicitly switching the state to the correct one. Fixes piglit tests 16384-consecutive-chars.frag and 16385-consecutive-chars.frag.
2011-03-03glcpp/tests: Update 063-comments.c.expected to match output.Kenneth Graunke
The expected result has been out of sync with what glcpp produces for some time; glcpp's actual result seems to be correct and is very close to GCC's cpp. Updating this will make it easier to catch regressions in upcoming commits.

2011-03-03scons: Ensure generated headers are in the include path.José Fonseca
2011-03-02glsl: Remove unused glcpp/Makefile.am.Kenneth Graunke
This is a remnant of when glsl2 lived in its own repository.
2011-03-02glsl: Remove 'tests' subfolder.Kenneth Graunke
These have long since moved to piglit and aren't useful to have here.
2011-03-01scons: Use Flex and Bison to generate lexer/parser files.Kenneth Graunke
This gets it building again here; I'll leave it up to the SCons maintainers to make further improvements.
2011-03-01glsl: Rename .lpp to .ll and .ypp to .yy.Kenneth Graunke
SCons has built-in support for .ll and .yy, but not .lpp and .ypp. Since there's no real benefit to using the old names, change them.

2011-02-15linker: Fix off-by-one error implicit array sizingIan Romanick
Arrays are zero based. If the highest element accessed is 6, the array needs to have 7 elements. Fixes piglit test glsl-fs-implicit-array-size-03 and bugzilla #34198. NOTE: This is a candidate for the 7.9 and 7.10 branches.
2011-02-15glsl: Reinstate constant-folding for division by zeroChad Versace
Fixes regression: https://bugs.freedesktop.org/show_bug.cgi?id=34160 Commit e7c1f058d18f62aa4871aec623f994d7b68cb8c1 disabled constant-folding when division-by-zero occured. This was a mistake, because the spec does allow division by zero. (From section 5.9 of the GLSL 1.20 spec: Dividing by zero does not cause an exception but does result in an unspecified value.) For floating-point division, the original pre-e7c1f05 behavior is reinstated. For integer division, constant-fold 1/0 to 0.
2011-02-15Revert "glsl: Fix constant-folding for reciprocal expressions"Chad Versace
This reverts commit b3cf92aa916ee0537ee37723c23a9897ac9cd3e0. The reverted commit prevented constant-folding of reciprocal expressions when the reciprocated expression was 0. However, since the spec allows division by zero, constant-folding *is* permissible in this case. From Section 5.9 of the GLSL 1.20 spec: Dividing by zero does not cause an exception but does result in an unspecified value.
2011-02-11mesa: Optionally build a dricore support library (v3)Christopher James Halse Rogers
This an adds --enable-shared-dricore option to configure. When enabled, DRI modules will link against a shared copy of the common mesa routines rather than statically linking these. This saves about 30MB on disc with a full complement of classic DRI drivers. v2: Only enable with a gcc-compatible compiler that handles rpath Handle DRI_CFLAGS without filter-out magic Build shared libraries with the full mklib voodoo Fix typos v3: Resolve conflicts with talloc removal patches Signed-off-by: Christopher James Halse Rogers <christopher.halse.rogers@canonical.com>
2011-02-11glcpp: regerated filesIan Romanick
These should have been committed right after fd1252ab, but they were missed. Soon, we'll never have to do this again...
2011-02-11glsl: Regenerate files modified by previous commitsIan Romanick
2011-02-11glsl: Finish out the reduce/reduce error fixesIan Romanick
Track variables, functions, and types during parsing. Use this information in the lexer to return the currect "type" for identifiers. Change the handling of structure constructors. They will now show up in the AST as constructors (instead of plain function calls). Fixes piglit tests constructor-18.vert, constructor-19.vert, and constructor-20.vert. Also fixes bugzilla #29926. NOTE: This is a candidate for the 7.9 and 7.10 branches.
2011-02-11glsl: Eliminate reduce/reduce conflicts in glsl grammarKeith Packard
This requires lexical disambiguation between variable and type identifiers (as most C compilers do). Signed-off-by: Keith Packard <keithp@keithp.com> NOTE: This is a candidate for the 7.9 and 7.10 branches.

2011-02-10glsl/Makefile: glcpp doesn't need libglsl.a.Kenneth Graunke
Also, add a 'glcpp' target so you can type 'make glcpp' instead of 'make glcpp/glcpp'.
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.
