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

e64a4aaacb ir_to_mesa: Note which of our expr ops are unsupported 1.30 features. 2010-06-30 16:18:06 -07:00

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.

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.

c64da87611 ir_to_mesa: Fix the indexing of attributes in the program's Attributes. 
This fixes GetAttribLocation returning VERT_ATTRIB_GENERIC1 instead of 1,
caught by glsl-dlist-getattriblocation.

c7f4ff193a glsl2: Fix storing of dead memory in the symbol table. 
decl->identifier is part of the AST, so it doesn't live very long.
Instead, add var->name which is owned by var.

c6099a65f8 glsl2: Create new talloc contexts the "right" way. 2010-06-30 13:52:24 -07:00
Kenneth Graunke
953ff1283d glsl2: Use _mesa_glsl_parse_state as the talloc parent, not glsl_shader. 
_mesa_glsl_parse_state should be the parent for all temporary allocation
done while compiling a shader.  glsl_shader should only be used as the
parent for the shader's final IR---the _result_ of compilation.

Since many IR instructions may be added or discarded during optimization
passes, IR should not ever be allocated to glsl_shader directly.

Done via sed -i s/talloc_parent(state)/state/g and s/talloc_parent(st)/st/g.

This also removes a ton of talloc_parent calls, which may help performance.

ef5f194831 linker: Don't dynamically allocate slots for linked shaders 
The can be at most one shader per stage.  There are currently only two
stages.  There is zero reason to dynamically size this array.

849e18153c glsl2: Use Mesa's gl_shader_program instead of our own struct glsl_program. 
This avoids more allocation and shuffling of data around.
 2010-06-30 12:01:42 -07:00

0eda9ae0a6 glsl2: Make function names and variable names be children of the node. 
This avoids losing their memory when the parser state is freed.

Eric Anholt
16b68b1952 glsl2: Move our data from a glsl_shader* on the side to the main gl_shader *. 
This saves recompiling at link time.  gl_shader->ir is made a pointer
so that we don't have to bring exec_list into mtypes.h.

12681610f5 glsl_type: Remove vector and matrix constructor generators 
All scalar, vector, and matrix constructors are generated in-line
during AST-to-HIR translation.  There is no longer any need to
generate function versions of the constructors.

699b247661 glsl2: Don't flatten constructor parameters to scalars 
Now that all scalar, vector, and matrix constructors are emitted
in-line, the parameters to these constructors should not be flattened
to a pile of scalars.  Instead, the functions that emit the in-line
constructor bodies can directly write the parameters to the correct
locations in the objects being constructed.

6315b68f5f ir_swizzle: Add new constructor, refactor constructors

the meat of the two constructors to an init_mask method.

This doesn't do any control flow analysis to ensure that the return
statements are actually reached.

18707eba1c glsl2: Check that returned expressions match the function return type. 
From my reading of the specification, implicit conversions are not
allowed.  ATI seems to agree, though nVidia allows it without warning.
