On pre-gen6, this turns 4 instructions into 1. We could still do
better by folding the saturate into the instruction generating the
value if nobody else uses it, but that should be a separate pass.
|
|
Hardware pretty commonly has saturate modifiers on instructions, and
this can be used in codegen to produce those, without everyone else
needing to understand clamping other than min and max.
|
|
This hits a common case with min/max operations.
|
|
|
|
This should make it a lot harder to forget to zero things.

When the semantics of write masks in assignments were changed, this
code was not correctly updated.
Fixes piglit test glsl-mat-from-vec-ctor-01.

This should save on the overhead of tree-walking and provide a
convenient place to add more instruction lowering in the future.

The vector operator collects 2, 3, or 4 scalar components into a
vector. Doing this has several advantages. First, it will make
ud-chain tracking for components of vectors much easier. Second, a
later optimization pass could collect scalars into vectors to allow
generation of SWZ instructions (or similar as operands to other
instructions on R200 and i915). It also enables an easy way to
generate IR for SWZ instructions in the ARB_vertex_program assembler.

This may grow in the near future.

The operate just like ir_unop_sin and ir_unop_cos except that they
expect their inputs to be limited to the range [-pi, pi]. Several
GPUs require this limited range for their sine and cosine
instructions, so having these as operations (along with a to-be-written
lowering pass) helps this architectures.
These new operations also matche the semantics of the
GL_ARB_fragment_program SCS instruction. Having these as operations
helps in generating GLSL IR directly from assembly fragment programs.

Now that we have fetch shaders, the full range of VS resources
can be used for sampling.
|
|
Makes the code much clearer.

Use fetch shader instead of having fetch instruction in the vertex
shader. Allow to restrict shader update to a smaller part when
vertex buffer input layout changes.

Occlusion query on evergreen need the event index field to be

Condiation moves with a condition of (a < 0), (a > 0), (a <= 0), or (a
>= 0) can be generated with "a" directly as an operand of the CMP
instruction. This doesn't help much now, but it will help with
assembly shaders that use the CMP instruction.
|
|
This eliminates the need in some cames to validate that an rvalue is
an ir_constant before checking to see if it's 0 or 1.
|
|
This should prevent the field going unset in the future. See bug
http://bugs.freedesktop.org/show_bug.cgi?id=31544 for background.
Also remove unneeded calls to clear_teximage_fields().
Finally, call _mesa_set_fetch_functions() from the
_mesa_init_teximage_fields() function so callers have one less
thing to worry about.

this should at least make app use the same paths as they would for a real
driver.

Fix this GCC warning.
ir.cpp: In static member function
'static unsigned int ir_expression::get_num_operands(ir_expression_operation)':

Remove version.h and context.h from core.h.

xmesa_get_name returns the name of the st_api, which is the same as
MESA_VERSION_STRING.

It will be used to implement wglShareLists. Fill st_context_iface::copy
for glXCopyContext as well.

It is the name of the rendering API. This field is informative.

If an instruction writes reg but nothing later uses it, then we don't
need to bother doing it. Before, we were just killing code that was
never read after it was ever written.
This removes many interpolation instructions for attributes with only
a few comopnents used. Improves nexuiz high-settings performance .46%
+/- .12% (n=3) on my Ironlake.

The type of the num/count parameter to glProgramParameters4[df]vNV()
changed so some API dispatch code needed updates too.

This should fix the remaining buffer alignment issues in r600g.

It's annoying to use test suites under a Mesa debug build because
pretty output is cluttered with stderr's continuous reports that
you're still using the debug driver.

The new usage message lists possible command line options. (Newcomers to Mesa
currently have to trawl through the source to find the command line options,
and we should save them from that trouble.)
Example Output
--------------
usage: ./glsl_compiler [options] <file.vert | file.geom | file.frag>
Possible options are:
--glsl-es
--dump-ast
--dump-hir
--dump-lir
--link

This adds sentinel values to the ir_expression_operation enum type:
ir_last_unop, ir_last_binop, and ir_last_opcode. They are set to the
previous one so they don't trigger "unhandled case in switch statement"
warnings, but should never be handled directly.
This allows us to remove the huge array of 1s and 2s in
ir_expression::get_num_operands().
