This causes the following tests to pass:
glslparsertest/shaders/array4.frag
glslparsertest/shaders/array5.frag
This causes the following tests to fail. These shaders were
previously failing to compile, but they were all failing for the wrong
reasons.
glslparsertest/shaders/array3.frag
Add some checking for vertex shader inputs / attributes
This causes the following tests to pass:
glslparsertest/shaders/attribute.vert
glslparsertest/shaders/attribute1.vert
glslparsertest/shaders/attribute2.vert
Use call-by-reference for apply_implicit_conversion
I'm not sure if this is a win or not. It makes the code in
apply_implicit_conversion more clear, but it obscures the fact that it
may change the pointers.
This causes the following tests to pass:
glslparsertest/shaders/CorrectVersion.V110.frag
shaders/glsl-vs-sqrt-zero.frag
shaders/glsl-vs-sqrt-zero.vert
This causes the following tests to fail. These shaders were
previously failing to compile, but they were all failing for the wrong
reasons.
glslparsertest/shaders/attribute1.vert
glslparsertest/shaders/attribute2.vert
glslparsertest/shaders/main2.vert
Implement ir_if (for if-statments) and conversion from AST
The following tests now pass:
glslparsertest/shaders/if1.frag
glslparsertest/shaders/if2.frag
The following tests that used to pass now fail. It appears that most
of these fail because ast_nequal and ast_equal are not converted to HIR.
shaders/glsl-unused-varying.frag
shaders/glsl-fs-sqrt-branch.frag
Implement exp2() and log2(), and make ir_unop_exp and ir_unop_log be base e.
Making the base e functions IR operations is not a clear win. i965
doesn't support it, it doesn't look like r600 supports it, but r500
does. It should be easily supportable as a lowering pass, though.
Following a discussion in #dri-devel, I think this makes more sense
than implementing it as RSQ RCP CMP as Mesa did. The i965 has a
hardware sqrt that should work, and AMD is suppposed to be able to
implement it as RSQ RCP with an alternate floating point mode so that
the 0.0 case is handled like we want.
