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.
2011-01-31glsl: Introduce a new "const_in" variable mode.Kenneth Graunke
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.
2011-01-31glsl: Change texel offsets to a single vector rvalue.Kenneth Graunke
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.

2010-11-15glsl: Rename various ir_* files to lower_* and opt_*.Kenneth Graunke
This helps distinguish between lowering passes, optimization passes, and other compiler code.
