Handle both NV vertex programs and NV vertex state programs passed to
glProgramStringARB.

Fixes bug 24967.
|
|
No statistically significant performance difference at n=3 with either
openarena or my GL demo, but cutting program size seems like a good
thing to be doing for the hypothetical app that has a working set near
icache size.

This should fix issues with antialiased lines in GLSL.
|
|
The PINTERP code should be faster for brw_wm_glsl.c now since brw_wm_emit.c's
had been improved, and pixel_w should no longer stomp on a neighbor to dst.

This drops support for get_src_reg_imm in these, but the prospect of getting
brw_wm_pass*.c onto our GLSL path is well worth some temporary pain.
|
|
This matches brw_wm_emit.c, which we'll be using shortly. There's a
possible penalty here in that we'll allocate registers for unused channels,
since we aren't doing ref tracking like brw_wm_pass*.c does. However, my
measurements on GM965 don't show any for either OA or UT2004 with the GLSL
path forced.
|
|
Depending on the writemask or the opcode, we can often trim the source
channels considered used for dead code elimination. This saves actual
instructions on 965 in the non-GLSL path for glean glsl1, and cleans up
the writemasks of programs even further.

Running make with -j for the first time might fail because glapi headers
haven't been generated. This commit should make it more reliable.

drawtex.c was listed in LOCAL_ES1_SOURCES twice. My mistake when
merging the patches.
Also, run gl_apitemp.py with -c to silence warnings and add target
"install".

When the mode is on, the scripts would generate headers that are
suitable for OpenGL ES. There are two differences. One is that they
will generate function prototypes for OpenGL ES specific functions. The
other is that, when a function has multiple names, SET/GET/CALL macros
would be generated for each of names.

This fixes the dead code elimination to work on the particular code
mentioned in the previous commit.
|
|
GLSL code such as:
vec4 result = {0, 1, 0, 0};
gl_FragColor = result;
emits code like:
0: MOV TEMP[0], CONST[0];
1: MOV OUTPUT[1], TEMP[0];
and this replaces it with:
0: MOV TEMP[0], CONST[0];
1: MOV OUTPUT[1], CONST[0];
Even when the dead code eliminator fails to clean up a now-useless MOV
instruction (since it doesn't do live/dead ranges), this should at reduce
dependencies.
|
|
This cleans up a bunch of instructions in GLSL programs to have limited
writemasks, which would translate to wins in shaders that hit the i965
brw_wm_glsl.c path by depending less on in-driver optimizations. It will
also help hit other optimization passes I'm looking at.

This keeps the individual state files from having to export their
structures for brw_state_cache initialization.
|
|
I fixed it properly as of 7216679c1998b49ff5b08e6b43f8d5779415bf54.

Otherwise, we could lose track of rendering to that image, which could
easily happen during mipmap generation.
|
|
This is probably not 100% complete (bind vs unbind may still not pair up
exactly), but it should help out drivers which are relying on
FinishRenderTexture to be called when we're done rendering to a particular
texture level, not just when we're done rendering to the object at all.
This is the case for the one consumer of FinishRenderTexture() so far: the
gallium state tracker. Noticed when trying to make use of FRT() in the intel
driver.

This should do all the things that MI_FLUSH did, but it can be pipelined
so that further rendering isn't blocked on the flush completion unless
necessary.
|

gen2/3/4 are easier to say than "8xx, 915-945/g33/pineview, 965/g45/misc",
and compares on generation are often easier than stringing together a bunch
of chipset checks.

This should fix the memory leaks in the assembly parser without the
regressions.
The conflicts in program_lexer.l were related to changes in returning
strings between the branches (always return IDENTIFIER vs. returing
either IDENTIFIER or USED_IDENTIFIER).
The conflicts in program_parse.y were related to two changes in master
One change prints a variable name in an error message. The other
change adds outputVarSize to the OUTPUT_statement rule. The cause the
position of the IDENTIFIER to change from $2 to $3.
Conflicts:
src/mesa/shader/lex.yy.c
src/mesa/shader/program_lexer.l
src/mesa/shader/program_parse.tab.c
src/mesa/shader/program_parse.y

_mesa_parse_arb_{fragment,vertex}_program
The program structure passed to _mesa_parse_arb_program is just a
place holder. The stings that actually need to be released are only
known to the functions calling _mesa_parse_arb_program, so they should
be freed there.

This reverts commit 93dae6761bc90bbd43b450d2673620ec189b2c7a.
This change was completely broken when the parser uses multiple
strings in a single production. It would be nice if bug fixes could
initially land somewhere other than the stable branch.

This is primitive support for OpenGL ES. It uses a subset of mesa
sources to build libesXgallium.a and libesXapi.a, where X is 1 for
OpenGL ES 1.x, 2 for OpenGL ES 2.x. The static libraries serve the same
purpose as libmesagallium.a and libglapi.a do for OpenGL.
This is based on the work of opengl-es branch.
