Ian Romanick c178c74c27 Add tracking for extension based warnings 
Using '#extension foo: warn' instructs the compiler to generate a
warning when some feature of the extension 'foo' is used.  This patch
adds some infrastructure needed to support that for variables.

Similar changes will be needed for types and built-in functions.

Ian Romanick 62f62ca3b3 Partially fix comment handling in preprocessor directives. 
Multi-line /* */ comments are still broken.  I think this will wait to
be fixed until we have a real preprocessor.

Ian Romanick 8c46ed2490 Generate correct IR for do-while loops 
Previously the same code was generated for a while loop and a do-while
loop.  This pulls the code that generates the conditional break into a
separate method.  This method is called either at the beginning or the
end depending on the loop type.

Ian Romanick fad607a9be Add ir_loop to represent loops 
This touches a lot of files because everything derived from ir_visitor
has to be updated.  This is the primary disadvantage of the visitor pattern.

Ian Romanick 63f394203a Set lower bound on size implied by whole-array assignment 
When an unsized array is accessed with a constant extension index this
sets a lower bound on the allowable sizes.  When the unsized array
gets a size set due to a whole-array assignment, this size must be at
least as large as the implied lower bound.

This causes the following tests to pass:

    glslparsertest/glsl2/array-16.vert
 2010-04-05 14:35:47 -07:00
Ian Romanick 63038e18ad Allow dereference of vectors and matrices with []

Ian Romanick 9d975377ca Track whether whole-arrays are assignable 
In GLSL 1.10 this was not allowed, but in GLSL 1.20 and later it is.

This causes the following tests to pass:

    glslparsertest/glsl2/array-09.vert
    glslparsertest/glsl2/array-13.vert
 2010-04-02 17:17:47 -07:00
Ian Romanick 2d946634eb Whole structures are assignable 
Whole arrays are assignable in GLSL 1.20 and later, but it's not clear
how to handle that within the IR because the IR is supposed to be
shading language version agnostic.
