* glsl: Convert piles of foreach_iter to the newer foreach_list macro.Kenneth Graunke2014-01-131-2/+2
| | | | | | | | | | | | | foreach_iter and exec_list_iterators have been deprecated for some time now; we just hadn't ever bothered to convert code to the newer foreach_list and foreach_list_safe macros. In these cases, we aren't editing the list, so we can use foreach_list rather than foreach_list_safe.

* glsl: Put a bunch of optimization visitors under anonymous namespaces.Eric Anholt2012-06-111-0/+3
| | | | | | | | | | | | | | | | | 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). No statistically significant difference with n=322 on glslparsertest on a yofrankie shader intended to test compiler performance. Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
* glsl: Improve the local dead code optimization to eliminate unused channels.Eric Anholt2012-05-171-23/+126
| | | | | | | | | | | | | | | Total instructions: 261582 -> 261316 135/2147 programs affected (6.3%) 36752 -> 36486 instructions in affected programs (0.7% reduction) This excludes a tropics shader that now gets 16-wide mode and throws off the numbers. 5 shaders are hurt: two extra MOVs in 4 tropics shaders it looks like because we don't split register names according to independent webs, and one gstreamer shader where it looks like try_rewrite_rhs_to_dst() is falling on its face. This should also help avoid a regression in VSes from idr's ARB programs to GLSL work.
* glsl: Convert ir_call to be a statement rather than a value.Kenneth Graunke2012-04-021-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Aside from ir_call, our IR is cleanly split into two classes: - Statements (typeless; used for side effects, control flow) - Values (deeply nestable, pure, typed expression trees) Unfortunately, ir_call confused all this: - For void functions, we placed ir_call directly in the instruction stream, treating it as an untyped statement. Yet, it was a subclass of ir_rvalue, and no other ir_rvalue could be used in this way. - For functions with a return value, ir_call could be placed in arbitrary expression trees. While this fit naturally with the source language, it meant that expressions might not be pure, making it difficult to transform and optimize them. To combat this, we always emitted ir_call directly in the RHS of an ir_assignment, only using a temporary variable in expression trees. Many passes relied on this assumption; the acos and atan built-ins violated it. This patch makes ir_call a statement (ir_instruction) rather than a value (ir_rvalue). Non-void calls now take a ir_dereference of a variable, and store the return value there---effectively a call and assignment rolled into one. They cannot be embedded in expressions. All expression trees are now pure, without exception.

* glsl: Add using statements for standard library functions.Vinson Lee2011-02-031-0/+2
| | | | | | | | | | | | | 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.
