| | | | | | | | | | | | At this point in the linking, we've totally lost track of the struct gl_uniform_buffer that this pointed to in the original unlinked shader, so we do a nasty n^2 walk to find it the new one based on the variable name.

* mesa: Set gl_fragment_program::UsesKill in do_set_program_inouts.Paul Berry2012-07-201-0/+14
| | | | | | | | | | | | | | | | | | | | | Previously, the code for setting this flag for GLSL programs was duplicated in three places: brw_link_shader(), glsl_to_tgsi_visitor, and ir_to_mesa_visitor. In addition to the unnecessary duplication, there was a performance problem on i965: brw_link_shader() set the flag before doing its final round of optimizations, which meant that if the optimizations managed to eliminate all the discard operations, the flag would still be set, resulting (at least in theory) in slower performance. This patch consolidates all of the code that sets UsesKill for GLSL programs into do_set_program_inouts(), which already is doing a similar job for UsesDFdy, and which occurs after i965's final round of optimizations. Non-GLSL programs (ARB programs and the state tracker's glBitmap program) are unaffected. Reviewed-by: Eric Anholt <[email protected]>

| | | | | | | | | | | | | | | | This patch updates the ir_set_program_inouts_visitor so that it also sets gl_fragment_program::UsesDFdy. This is a bit of a hack (since dFdy() isn't an input or an output), but there's no other obvious visitor to squeeze this functionality into, and it would be silly to create a brand new visitor just for this purpose. v2: use local 'fprog' var to avoid repeated casting.

| | | | | | | | | | | | | | | | Commit 68e04cc6 was tested using automake-1.11. Unfortunately, automake-1.12 made a "slightly backward-incompatible change" in the use of yacc with C++, and for a .yy file, the generated header file is now named .hh, not .h To work with both, write our own rule for running yacc, which generates a header file named .h, rather than using automake's rule. Also, remove things from BUILD_SOURCES which don't need to be there Also, update EXCLUDE rules in doxygen/glsl.doxy, for change of generated files from .cpp -> .cc, and glsl_lexer.h has never existed.

* glsl: Remove unused ir_loop_jump::loop pointer.Kenneth Graunke2012-07-021-4/+0
| | | | | | | | | | | | | | | | | Commit 0c005bd7 intended to make ir_loop_jump::mode public, but also accidentally added a new pointer to the enclosing loop. Furthermore, it tried to initialize the new field by adding "this->loop = loop;" to the constructor, but since there is no loop parameter, this only initialized the field to itself---so it will likely be a garbage pointer. A lot of code, such as lower_jumps, allocates new loop jumps without setting this field appropriately, so any uses would probably just crash. Thankfully, there were none, so we can just delete the field.

* glsl: be more careful about counting varying vars in the linkerBrian Paul2012-06-271-1/+27
| | | | | | | | | | | | | Previously, we were counting gl_FrontFacing, gl_FragCoord and gl_PointCoord against the limit of varying variables. This prevented some valid shaders from linking. The other potential solution to this is to have the driver advertise more varying vars or set the GLSLSkipStrictMaxVaryingLimitCheck flag. But the above-mentioned variables aren't conventional varying attributes so it doesn't seem right to count them. Reviewed-by: Eric Anholt <[email protected]>

* glsl: glcpp: Move handling of #line directives from lexer to parser.Carl Worth2012-06-264-40/+55
| | | | | | | | | | | | | | | | | | | The GLSL specification requires that #line directives be interpreted after macro expansion. Our existing implementation of #line macros in the lexer prevents conformance on this point. Moving the handling of #line from the lexer to the parser gives us the macro expansion we need. An additional benefit is that the preprocessor also now supports comments on the same line as #line directives. Finally, the preprocessor now emits the (fully-macro-expanded) #line directives into the output. This allows the full GLSL compiler to also see and interpret these directives so it can also generate correct line numbers in error messages.

* glsl: Consistently use length-based ralloc string functions for info_log.Carl Worth2012-06-261-14/+24
| | | | | | | | | | | | | | | | | | | | | Commit b823b99ec0f13af257dcd885f436a4d294c6222a switched from using functions such as ralloc_asprintf and ralloc_strcat to ralloc_asprintf_rewrite_tail. This change maintains the string's length as a aparamter that is updated by the ralloc functions (rather than recomputing it with strlen over and over). However, the change failed to updated two locations (glcpp_error and glcpp_warning), with the result that the string's length wasn't updated by these calls. Then, subsequent calls to other ralloc_asprintf_rewrite_tail would overwrite the text appended by glcpp_error. This commit fixes the two missing updates, and restores line numbers to the output of glcpp error messages, (as noticed by a glcpp unit test case that has been failing since the above-mentioned commit).

| | | | | | | | | | | | | | | | | A strict reading of the GLSL specification would have this be an error, but we've received reports from users who expect the preprocessor to interepret undefined macros as 0. This is the standard behavior of the rpeprocessor for C, and according to these user reports is also the behavior of other OpenGL implementations. So here's one of those cases where we can make our users happier by ignoring the specification. And it's hard to imagine users who really, really want to see an error for this case. The two affected tests cases are updated to reflect the new behavior. Signed-off-by: Carl Worth <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>

| | | | | | | | | | | | | | | Previously, we performed conversions from float->uint by a two step process: float->int->uint. However, on platforms that use saturating conversions (e.g. i965), this didn't work, because if the source value was larger than the maximum representable int (0x7fffffff), then converting it to an int would clamp it to 0x7fffffff. This patch just adds the new opcode; further patches will adapt optimization passes and back-ends to use it, and then finally the ast_to_hir logic will be modified to emit the new opcode.

| | | | | | | | | | | | | | | | | Because these classes are used entirely from their own source files and not from separate DSOs, the linker gets to produce massively less code. This cuts about 13k of text in the libdricore case. In the non-libdricore case, the additional linkage information allows the compiler to inline some code, so libglsl.a size actually increases by about 300 bytes. For a dricore build, improves shader_runner runtime on glsl-fs-copy-propagation-texcoords-1 by 0.21% +/- 0.03% (n=353574, outliers removed).

| | | | | | | | | | | | | Now we have just one library of "all of Mesa core" instead of both libdricore and libglsl that drivers link against. I did this change in a sort of nonrecursive make fashion: the generated files are still produced in the non-automake build, like the rest of dricore, but the GLSL files are stuffed into libdricore without building a convenience library in src/glsl (even though we could now). This would make a bit more sense if glsl was just another dir under src/mesa, because right now I had to contort the prefix variable name to look another ../ level up.
