c476ba8fe2 Add a completely bogus implementation of the noise[1234] builtins. 
idr suggested this.  Eventually we will need a real one.

855fcb22c1 Implement 'acos' builtin. 
This is tacked on to the end of the 'asin' file because acos calls asin,
whech means asin needs to be defined first.  Alphabetical order fail.

8331d48948 Don't call _mesa_glsl_initialize_types for every builtin function. 
This was clearly wrong; types are now only initialized once.
 2010-06-09 11:14:58 -07:00
Kenneth Graunke
57503a22d7 Only initialize types after #extension directives have been processed. 
Since _mesa_glsl_initialize_types add types for various extensions, we
can't call it until after processing "#extension foo : disable" lines.

Fixes tex_rect_02.frag.

2f8b0435b0 Use array delete operator to delete an array 
This was detected by valgrind.  I think GCC still does the right
thing, but the C++ spec allows the compiler to do something
stupid... like crash or only delete the first entry in the array.

cfb3536f10 Bump GL_MAX_TEXTURE_COORDS from 2 to 4 
Every platform that supports GLSL sets GL_MAX_TEXTURE_COORDS to at
least 4, so hard-code 4 for now.

This causes the following tests to pass:

    glslparsertest/glsl2/norsetto-bumptbn_sh_fp.vert
    glslparsertest/glsl2/xreal-lighting-d-omni.vert
    glslparsertest/glsl2/xreal-lighting-db-omni.vert

19eb5896c4 Only allow global precision qualifier for int and float 
This causes the following tests to pass:

    glslparsertest/glsl2/precision-03.vert

9bcb67bdc4 Fix parsing of precision qualifiers 
This causes the following tests to pass:

     glslparsertest/glsl2/precision-02.vert
     glslparsertest/glsl2/precision-04.vert
     glslparsertest/glsl2/precision-06.vert

This causes the following test to fail.  This shader was previously
failing to compile, but it was failing for the wrong reasons.

15d162d7b1 Don't process empty shaders 
Some valid shaders, such as 'precision highp float;', evaluate to
empty sets of instructions.  This causes some of the optimization
stages to enter infinite loops.  Instead, don't bother processing the
empty ones.

6cd2a5cc4b Generate an error on empty declaration lists

384c051b8c ir_dereference_array always operates on an r-value 
ir_dereference_array::array is always an r-value.  If the dereference
is of a varaible, that r-value will be an ir_dereference_variable.
This simplifies the code a bit.

c8021ee01d Remove some cruft from the Makefile 
This was affecting the build, but the files don't actually exist.

0ca171908d Allow arrays of floats as varyings. 
The comment just above the code said arrays were OK, then it didn't
handle arrays.  Whoops.  Partially fixes CorrectUnsizedArray.frat.

f03acfc7d7 builtins: Add the mix(gentype, gentype, float) variant. 
The broken-in-mesa Regnum Online shader now parses, except for its
preprocessor usage.

336b4ad8c7 Handle GLSL 1.20 implicit type conversions. 
We were nicely constructing a new expression for the implicit type
conversion, but then checking that the previous types matched instead
of the new expression's type.  Fixes errors in Regnum Online shaders.

65122e9e80 ir_constant_variable: New pass to mark constant-assigned variables constant. 
This removes a bunch of gratuitous moving around of constant values
from constructors.  Makes a shader ir I was looking at for structure
handling almost readable.

f389862006 ir_constant_folding: Look at instructions in functions.
