* glsl: Add a visitor to determine whether a uniform block is ever usedIan Romanick2013-01-251-0/+1

* linker: Refactor intra-stage block compatabililty testingIan Romanick2013-01-251-0/+1
| | | | | | | | | | | | | | | | Also slightly change the compatibility test. Instead of comparing the offsets of the block variables, compare the packing mode of the blocks. Ideally we don't want to assign the offsets until a later stage of linking. This is put in a new file called link_uniform_blocks.cpp. Some new functions related to uniform blocks are going to live in that file as well.

* glsl: Separate varying linking code to its own file.Paul Berry2013-01-081-0/+1
| | | | | | | | linker.cpp is getting pretty big, and we're about to add even more varying packing code, so split out the linker code that concerns varyings to its own file. Reviewed-by: Kenneth Graunke <[email protected]>
* glsl: Add a lowering pass for packing varyings.Paul Berry2012-12-141-0/+1
| | | | | | | | | | | | | | This lowering pass generates GLSL code that manually packs varyings into vec4 slots, for the benefit of back-ends that don't support packed varyings natively. No functional change--the lowering pass is not yet used. Reviewed-by: Eric Anholt <[email protected]> v2: Don't use ir_hierarchical_visitor--just loop over instructions directly. Also, make the names of the packed varyings include the names of the original varyings that were packed into them.

* glsl: Add a lowering pass to turn complicated UBO references to vector loads.Eric Anholt2012-08-071-0/+1
| | | | | | | | | | | v2: Reduce the impenetrable code in emit_ubo_loads() by 23 lines by keeping the ir_variable as the variable part of the offset from handle_rvalue(), and track the constant offsets from that with a plain old integer value, avoiding a bunch of temporary variables in the array and struct handling. Also, fix file description doxygen. v3: Fix a row vs col typo, and fix spelling in a comment. Reviewed-by: Eric Anholt <[email protected]>
* automake: convert libglslJon TURNEY2012-07-131-2/+2
| | | | | | | | | | | | | | | | | | | | v2: Use AM_V_GEN to silence generated code rules. Add BUILT_SOURCES to CLEANFILES v3: - Fix an accidental // in a path - Use automake make rules for lex/yacc rather than writing our own - Update .gitignore appropriately - Build a libglcpp convenience library rather than awkwardly including the files in libglsl and delegating the generation - Remove libglsl.a compatibility link on clean v4: - Automake's rules for lex/yacc make .cc if source is .ll or .yy, and apparently we must use those extensions "because of scons", so update everywhere glsl_parser.cpp -> glsl_parser.cc and glsl_lexer.cpp -> glsl_lexer.cc. This fixes 'make tarballs' and building with dricore enabled. Signed-off-by: Jon TURNEY <[email protected]> Reviewed-by: Eric Anholt <[email protected]> Tested-by: Matt Turner <[email protected]>

* glsl: Create an ir_builder helper for hand-generating IR.Eric Anholt2012-04-131-0/+1
| | | | | | | | | | | | | | The C++ constructors with placement new, while functional, are extremely verbose, leading to generation of simple GLSL IR expressions like (a * b + c * d) expanding to many lines of code and using lots of temporary variables. By creating a new ir_builder.h that puts simple generators in our namespace and taking advantage of ralloc_parent(), we can generate much more compact code, at a minor runtime cost. v2: Replace ir_instruction usage with just ir_rvalue. v3: Drop remaining missed as_rvalue() in v2.

* glsl: Add an array splitting pass.Eric Anholt2012-04-111-0/+1
| | | | | | | | | | | | | | | | | I've had this code laying around almost done for a long time. The idea is like opt_structure_splitting, that we've got a bunch of transforms at the GLSL IR level that only understand scalars and vectors, which just skip complicated dereferences. While driver backends may manage some optimization after they split matrices up themselves, it would be better to bring all of our optimization to bear on the problem. While I wasn't expecting changes quite yet, a few programs end up winning: a gstreamer convolution shader, and the Humus dynamic branching demo: Total instructions: 269430 -> 269342 3/2148 programs affected (0.1%) 1498 -> 1410 instructions in affected programs (5.9% reduction)
