2010-08-04glsl2: Remove the shader_in/shader_out tracking separate from var->mode.Eric Anholt
I introduced this for ir_dead_code to distinguish function parameter outvals from varying outputs. Only, since ast_to_hir's current_function is unset when setting up function parameters (they're needed for making the function signature in the first place), all function parameter outvals were marked as shader outputs anyway. This meant that an inlined function's cloned outval was marked as a shader output and couldn't be dead-code eliminated. Instead, since ir_dead_code doesn't even look at function parameters, just use var->mode. The longest Mesa IR coming out of ir_to_mesa for Yo Frankie drops from 725 instructions to 636.

2010-07-20glsl2: Add and use new variable mode ir_var_temporaryIan Romanick
This is quite a large patch because breaking it into smaller pieces would result in the tree being intermitently broken. The big changes are: * Add the ir_var_temporary variable mode * Change the ir_variable constructor to take the mode as a parameter and correctly specify the mode for all ir_varables. * Change the linker to not cross validate ir_var_temporary variables. * Change the linker to pull all ir_var_temporary variables from global scope into 'main'.
