9acf618f24 glsl2: Remove dead member from dead code visitor. 2010-07-01 11:07:22 -07:00
Eric Anholt
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.

e277d5c1f6 gallivm: Setup a global optimization pass. 
Modules are still free to setup their own optimization passes, but for the
normal case it should not be necessary.

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.

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.

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.

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.

75acb896c6 glu: Fix some compiler warnings in libtess 
When compiled with the more aggressive compiler warnings such as
-Wshadow and -Wempty-body the libtess code gives a lot more
warnings. This fixes the following issues:

* The 'Swap' macro tries to combine multiple statements into one and
  then consume the trailing semicolon by using if(1){/*...*/}else.
  This gives warnings because the else part ends up with an empty
  statement. It also seems a bit dangerous because if the semicolon
  were missed then it would still be valid syntax but it would just
  ignore the following statement. This patch replaces it with the more
  common idiom do { /*...*/ } while(0).

* 'free' was being used as a local variable name but this shadows the
  global function. This has been renamed to 'free_handle'

* TRUE and FALSE were being unconditionally defined. Although this
  isn't currently a problem it seems better to guard them with #ifndef
  because it's quite common for them to be defined in other headers.

a2311400fe llvmpipe: Add a new scene state to describe scenes which only have state changes. 
It's a rare condition, but it may happen if all primitives are
clipped/culled.

For now we just do a no-op rasterization, but we could bypass it.
