e45a982313 Make hashtable.h be C++ friendly 2010-07-06 15:00:46 -07:00

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.

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.

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.

8f25d198e5 ir_to_mesa: Add support for scalar * mat, vec * mat. 
This is not tested by piglit currently.

b61f4241f3 ir_to_mesa: Add support for shadow comparison to texture instructions. 
piglit lacks tests for this currently.

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.

9a0e421983 glsl2: Add a pass to break ir_binop_div to _mul and _rcp. 
This results in constant folding of a constant divisor.

efb6b24223 glsl2: Append _TOK to some parser tokens 
This prevents conflicts with defines elsewhere in Mesa and allows
including mtypes.h in the compiler.

06143ea094 glsl2: Conditionally define preprocessor tokens for optional extensions 
The only optional extension currently supported by the compiler is
GL_EXT_texture_array.

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.

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.

8a1f186cc5 glsl2: Add a pass to convert mod(a, b) to b * fract(a/b). 
This is used by the Mesa IR backend to implement mod, fixing glsl-fs-mod.

d925c91730 glsl2: Add ir_unop_fract as an expression type. 
Most backends will prefer seeing this to seeing (a - floor(a)), so
represent it explicitly.

5e4dd061d1 ir_to_mesa: Add support for discard instructions.

Eric Anholt
e558786a3e i965: Add support for OPCODE_SSG. 
The old compiler didn't use SSG, and instead emitted SGT/SGT/SUB.  We
can do a little better for SSG than we do for the SGT series.
 2010-06-30 17:29:09 -07:00

d6ebe9b16b ir_to_mesa: Add missing no-op type conversions.

02d615306e glsl2: Fix reversed value of step(). 
It's 0.0 if x < edge, not 1.0.  Partial fix for glsl-fs-step.

4e16a7b526 glsl2: Fix up the implementation of fract() for vector types. 
There's no need to split each vector component out, just do vector ops.
 2010-06-30 15:59:07 -07:00
Eric Anholt
285ff93819 ir_to_mesa: Initialize the (we never use it) abs field of Mesa src regs. 2010-06-30 15:49:04 -07:00

Eric Anholt
97eba76b8c glsl2: Allow a fragment shader to not write a color. 
I can't find any text justifying this check, and it caused a
reasonable-looking shader in glsl-bug-22603 (which writes only
gl_FragDepth) to fail.

3e2127b9de mesa: Don't look in unallocatd param slots for parameter values. 
glsl-derivs would add 40.0, 0.0, and 1.0 in order.  When we went
looking for 0.0, we'd find it in the second slot of the param, and use
it, but param->Size would still be 1.  When we went to add 1.0 and
didn't find it, we'd put allocate it to that second slot and the 0.0
would actualy end up being 1.0.

Fixes glsl-derivs, glsl-deriv-varyings.
