f8946699ec glsl2: Add definitions of the builtin constants present in GLSL 1.10. 
Fixes:
glsl1-built-in constants

1245babe0c glsl2: Fix asin() implementation. 
I'd flipped around the order of two operations in paren-balancing
adventures, and left out the multiply by sign(x) required for negative x.

Fixes:
glsl1-acos(vec4) function
glsl1-asin(vec4) function
glsl1-atan(vec4) function

117d154b4d glsl2: notEqual() produces a boolean value, not the base type of the args. 
Fixes:
glsl1-vector relational (bvec2 ==,!=)
glsl1-vector relational (vec4 !=)

18ab797d3a ir_to_mesa: Fix swizzled writemasks with swapped component ordering. 
I hadn't noticed you could do this, but glsl1 tests caught it.  Fixes:
glsl1-Swizzled writemask
glsl1-Swizzled writemask (2)
glsl1-Swizzled writemask (rgba)
glsl1-Swizzled writemask (stpq)

1a03a644d2 linker: Remove redundant check for 'main' in shaders 
This is now handled in link_intrastage_shaders.

Ian Romanick
532c2d3085 linker: look up function signatures during linking instead of using callee 
Instead of using ir_call::callee, search for the signature in the
linked shader.  This will allow resolving calls from functions
imported from other shaders.  The ir_call::callee pointer in the
imported function will still reference a signature in the original shader.

5adbf0bff1 linker: Pull find_matching_signature out of call_link_visitor 
The list of shaders to search needs to be provided as an explicit
parameter to support coming changes.  At that point there is no reason
for it to be in the class.  Also, fix some of the 'const' decorators.

b95897b89d glsl2: Explicitly walk lists in ir_function::parameter_lists_match 
Give ir_function::parameter_lists_match_exist similar treatment.  Make
the parameters const, and propogate the constness as far as it will
trivially go.

8fe8a814b0 linker: First bits of intrastage, intershader function linking 
This handles the easy case of linking a function in a different
compilation unit that doesn't call any functions or reference any
global variables.

61a44ccaef exec_list: Fix foreach_list_safe. 
It now works correctly when nodes are removed, as it was originally
intended to do; it no longer processes nodes added to the list before
the current node, nor those added immediately after the current node.

This matches the behavior of Linux's list_for_each_safe.

303c99f12f linker: Use foreach_list_safe in move_non_declarations 
The node being processed may be removed from the list and put in a
different list.  Not using the safe version caused list processing to
change streams after moving a node.

9303e358cb linker: Move global instructions from the linked shader first 
For the shader containing 'main', use the linked shader (i.e., the
clone of the original shader that contained main) as the source for
global instructions to move into main.

5304493c40 glsl2: Fix lexing of octal values, including "0". 
When faced with a constructor like 'ivec4(0, 2, 0, 0)', we would
manage to get a value of 2 instead of 0 for the first "0".  Usually 2
characters past "0" would point at some junk and lex as 0 anyway.

Fixes glsl-octal and glsl-unused-varyings.

82d4b9593b glsl2: Fix the expression type for atan's pi * sign(y).

29ce44ad2b glsl2: Add a pass for converting if statements to conditional assignment. 
This will be used on 915 and similar hardware of that generation.

d16044ad4d glsl2: Give IR nodes a type field. 
This is a big deal for debugging if nothing else ("what class is this
ir_instruction, really?"), but is also nice for avoiding building a
whole visitor or an if (node->as_whatever() || node->as_other_thing())
chain.

7b13014942 ir_to_mesa: Add support for function calls. 
Unlike the previous compiler, in this case we emit only one copy of
the function regardless of how many times it's called.

9be7f63813 glsl2: Make cross() be an expression operation. 
ARB_fp, ARB_vp, Mesa IR, and the 965 vertex shader all have
instructions for cross.  Shaves 12 Mesa instructions off of a
66-instruction shader I have.

79fed377f4 ir_constant_expression: Add support for ir_binop_min and ir_binop_max. 
These now work on scalar/vector combos. Semantically, if a is a scalar,
min(a, vec2(x,y)) == vec2(min(a,x), min(a,y))
