6de882334a glsl2: Clean up vec_index_to_cond_assign after the clone return type change. 2010-07-07 09:07:52 -07:00
Eric Anholt
773025b92c glsl2: Don't forget to walk the parameters to a function in the hv. 
Fixes segfaults from use after free after the steal of ir nodes and
free of the compile context.
 2010-07-07 09:07:52 -07:00

570dc0d400 glsl2: Avoid null deref in scalar constant unop expressions. 2010-07-07 09:07:52 -07:00
Eric Anholt
d4d630b72c glsl2: Put the declaration in the instruction stream before its initializer. 
This fixes a regression in the generated code from when I did the
ir_validate.cpp-driven rework of assignments.

a36334be02 glsl2: Add pass for supporting variable vector indexing in rvalues. 
The Mesa IR needs this to support vector indexing correctly, and
hardware backends such as 915 would want this behavior as well.

Fixes glsl-vs-vec4-indexing-2.
 2010-07-06 18:49:24 -07:00
Eric Anholt
2d1789e667 ir_to_mesa: Add support for conditional moves. 
Nothing generates conditional moves yet.

ca088cc277 glsl2: Clone methods return the type of the thing being cloned 
This is as opposed to returning the type of the base class of the hierarchy.
 2010-07-06 17:44:37 -07:00
Kenneth Graunke
f14e596f11 ir_constant_expression: Declare loop counting variables in the loops. 
Fixes "name lookup of 'c' changed" warning.
 2010-07-06 17:43:56 -07:00
Kenneth Graunke
f2dfac6d74 glsl2: Update TODO. 2010-07-06 16:03:33 -07:00
Kenneth Graunke
3f4a0b8bb0 ir_constant_expression: Add support for dot products. 2010-07-06 16:03:33 -07:00
Kenneth Graunke
cf80a4d177 ir_constant_expression: Add support for matrix multiplication. 
Also handles matrix/vector and vector/matrix multiplication.

Fixes piglit tests const-matrix-multiply-01.frag,
const-matrix-multiply-02.frag, and const-vec-mat.frag.
 2010-07-06 16:03:33 -07:00
Kenneth Graunke
37b3f9d0ed ir_constant_expression: Support scalar * vector and scalar * matrix. 
The test here is slightly different since we need to keep matrix
multiplication separate.

Fixes piglit tests const-vec-scalar-03.frag and const-mat-scalar-03.frag.
 2010-07-06 16:03:33 -07:00
Kenneth Graunke
dad35eb8b0 ir_constant_expression: Support scalar / vector and scalar / matrix. 
Fixes piglit tests const-vec-scalar-04.frag and const-mat-scalar-04.frag.
 2010-07-06 16:03:33 -07:00
Kenneth Graunke
97b44f040a ir_constant_expression: Support scalar - vector and scalar - matrix. 
Fixes piglit tests const-vec-scalar-02.frag and const-mat-scalar-02.frag.
 2010-07-06 16:03:33 -07:00
Kenneth Graunke
e74dcd7924 ir_constant_expression: Support scalar + vector and scalar + matrix. 
Fixes piglit tests const-vec-scalar-01.frag, const-vec-scalar-05.frag,
and const-mat-scalar-01.frag.
 2010-07-06 16:03:33 -07:00
Kenneth Graunke
6fc983b9bb ir_constant_expression: Assert that both operands share a base type. 2010-07-06 16:03:33 -07:00
Kenneth Graunke
6bc432e14e ir_constant_expression: Initialize op[0] and op[1] to NULL. 
This makes it easy to check if there is a second argument.
 2010-07-06 16:03:33 -07:00
Kenneth Graunke
c63a1db81f ir_constant_expression: Initialize all components of constant data to 0. 
This is probably just a good idea, and will come in useful when
implementing things like matrix multiplication.
 2010-07-06 16:03:32 -07:00

d1a1ee583e Add hash table helper functions for using pointers as hash keys 2010-07-06 15:00:46 -07:00
Ian Romanick
e45a982313 Make hashtable.h be C++ friendly 2010-07-06 15:00:46 -07:00
Eric Anholt
a0b3b93029 ir_to_mesa: Use the compiler-assigned locations for builtin attrs/varyings. 
The previous table didn't distinguish gl_Color for the VS and FS, so
we would use the FS's attribute index for the VS and read undefined.
This partially fixes glsl-routing to match its behavior on master.
 2010-07-06 14:05:51 -07:00
Kenneth Graunke
83035574db Refresh autogenerated file builtin_function.cpp. 2010-07-02 18:20:19 -07:00
Kenneth Graunke
7e908a6a27 glcpp: Add #error support. 2010-07-02 18:03:58 -07:00
Kenneth Graunke
2070f9f5be glsl2: Fix for dead strings being stored in the symbol table. 2010-07-02 18:03:58 -07:00
Kenneth Graunke
e2a358348b ir_to_mesa: Fix uninitalized value. 2010-07-02 18:03:58 -07:00
Kenneth Graunke
ddc3aa0783 glsl2/builtins: Use vector ops in the 130 version of "sign." 2010-07-02 18:03:58 -07:00
Kenneth Graunke
9a7ac272fb glsl2/builtins: Use vector ops in "smoothstep." 2010-07-02 18:03:58 -07:00
Eric Anholt
b0ac07e3de ir_to_mesa: Fix up implementation of ir_unop_exp. 
OPCODE_EXP is not to ir_unop_exp what OPCODE_EX2 is to ir_unop_exp2.
It's the weird VP approximation helper opcode.  Just implement it with
OPCODE_POW instead.

Fixes glsl-fs-exp.
 2010-07-02 17:06:32 -07:00
Eric Anholt
4e7d5d0e74 i965: Add support for the DP2 opcode, which we use for dot(vec2, vec2). 
The original glsl compiler would generate a.x * b.x + a.y * b.y, which
we would do mul+mul+add for instead of this mul+mac.

Fixes glsl-fs-dot-vec2.
 2010-07-02 17:06:23 -07:00
Eric Anholt
8f25d198e5 ir_to_mesa: Add support for scalar * mat, vec * mat. 
This is not tested by piglit currently.
 2010-07-02 17:06:08 -07:00
Eric Anholt
b61f4241f3 ir_to_mesa: Add support for shadow comparison to texture instructions. 
piglit lacks tests for this currently.
 2010-07-02 17:06:06 -07:00
Eric Anholt
d3983ca032 ir_to_mesa: Move projection handling out of ir_tex so txb and txl get it. 
Fixes:
glsl-fs-texture2dproj-bias
glsl-fs-texture2dproj-bias-2
 2010-07-02 17:06:05 -07:00

Eric Anholt
de75dfac4e ir_to_mesa: Add support for projected non-shadow/bias/lod texturing. 
Fixes:
glsl-fs-texture2dproj
glsl-fs-texture2dproj-2
 2010-07-02 14:50:02 -07:00

cab95c228b ir_to_mesa: Fix sparse swizzling of src regs when a writemask is present. 
Fixes glsl-fs-texture2d-masked.
 2010-07-02 14:08:20 -07:00
Eric Anholt
28faa12dc2 ir_to_mesa: Don't forget to run the Mesa IR optimization passes. 
With how we generate assignments, the trivial copy propagation in it
is really important, and some drivers will really want the register
allocation, too.
 2010-07-02 11:38:02 -07:00
Eric Anholt
9a0e421983 glsl2: Add a pass to break ir_binop_div to _mul and _rcp. 
This results in constant folding of a constant divisor.
 2010-07-02 11:27:06 -07:00

667f4e1940 glsl2: Conditionally allow optional extensions to be enabled 
The only optional extension currently supported by the compiler is
GL_EXT_texture_array.
 2010-07-01 20:40:08 -07:00
Ian Romanick
efb6b24223 glsl2: Append _TOK to some parser tokens 
This prevents conflicts with defines elsewhere in Mesa and allows
including mtypes.h in the compiler.
 2010-07-01 20:40:08 -07:00
Ian Romanick
06143ea094 glsl2: Conditionally define preprocessor tokens for optional extensions 
The only optional extension currently supported by the compiler is
GL_EXT_texture_array.
 2010-07-01 20:40:08 -07:00
Ian Romanick
2d12236117 glsl2: Define preprocessor tokens for extensions 
Currently only GL_ARB_draw_buffers and GL_ARB_texture_rectangle are
defined because those extensions are always enabled.  This make
tex_rect-03.frag pass.
 2010-07-01 20:40:08 -07:00

6f0823da09 glsl2: Support AST-to-IR translation of invariant keyword 2010-07-01 20:39:08 -07:00

12873fa4e3 glsl2: Don't bounds check unsize array redeclarations 
This along with several previous commits fix test CorrectUnsizedArray.frag.
 2010-07-01 14:10:19 -07:00

Ian Romanick
5466b63968 glsl2: Change order of semaintic checks on variable declarations 
This will make it easier to support more (valid) kinds of redeclarations.
 2010-07-01 12:56:49 -07:00
Eric Anholt
411fb36b7c ir_to_mesa: Fill in remaining ops, remove default case for expression types. 
We should now have support for all the expression types we need for
GLSL 1.20.
 2010-07-01 11:24:38 -07:00
Eric Anholt
8761fcc2bf ir_to_mesa: Add support for ir_unop_rcp.
