* gallivm: Fix lerping of (un)signed normalized numbers.José Fonseca2012-12-061-49/+43
| | | | | | | | | | | | | | | | | | Several issues actually: - Fix a regression in unsigned normalized in the rescaling [0, 255] to [0, 256] - Ensure we use signed shifts where appropriate (instead of unsigned shifts) - Refactor the code slightly -- move all the logic inside lp_build_lerp_simple(). This change, plus an adjustment in the tolerance of signed normalized results in piglit fbo-blending-formats fixes bug 57903 Reviewed-by: Brian Paul <[email protected]>

* android: Fix build of libmesa_programChad Versace2012-12-051-0/+3
| | | | | | | | | | | | | | | | | Commit 4097308 fixed the build in a questionable way. It worked at the time, but, as Ian pointed out, the fix would likely fail at a future commit due to the indeterminism of parallel builds. And that's exactly what happened; the fix no longer works. `mm -j4` on Fedora 17 fails for me. The problem is that there is no rule for program_parse.tab.h. To fix that, this patch adds a rule that makes program_parse.tab.c depend on program_parse.tab.h. Technically, the c file does not depend on the h file. However, because the two files are generated together by a single invocation of Bison, any rule that forces execution of Bison is sufficient. Signed-off-by: Chad Versace <[email protected]>

* i965: Add a debug flag for counting cycles spent in each compiled shader.Eric Anholt2012-12-0517-9/+524
| | | | | | | | | | | | | | | | | | | | | | This can be used for two purposes: Using hand-coded shaders to determine per-instruction timings, or figuring out which shader to optimize in a whole application. Note that this doesn't cover the instructions that set up the message to the URB/FB write -- we'd need to convert the MRF usage in these instructions to GRFs so that our offsets/times don't overwrite our shader outputs. Reviewed-by: Kenneth Graunke <[email protected]> (v1) v2: Check the timestamp reset flag in the VS, which is apparently getting set fairly regularly in the range we watch, resulting in negative numbers getting added to our 32-bit counter, and thus large values added to our uint64_t. v3: Rebase on reladdr changes, removing a new safety check that proved impossible to satisfy. Add a comment to the AOP defs from Ken's review, and put them in a slightly more sensible spot. v4: Check timestamp reset in the FS as well.
* i965: Add a flag for instructions with normal writemasking disabled.Eric Anholt2012-12-054-0/+4

* i965/fs: Add support for uniform array access with a variable index.Eric Anholt2012-12-044-24/+216
| | | | | | | | | | | | | Serious Sam 3 had a shader hitting this path, but it's used rarely so it didn't show a significant performance difference (n=7). It does reduce compile time massively, though -- one shader goes from 14s compile time and 11723 instructions generated to .44s and 499 instructions. Note that some shaders lose 16-wide mode because we don't support 16-wide and pull constants at the moment (generally, things looping over a few-element array where the loop isn't getting unrolled). Given that those shaders are being generated with 15-20% fewer instructions, it probably outweighs the loss of 16-wide.
* i965/fs: Conditionalize constant-index UBO load code and add comments.Eric Anholt2012-12-041-28/+33

* i965/fs: Allow source mods on gen7+ math.Eric Anholt2012-12-041-1/+1

* i965/fs: Add instruction emit for varying-index reads of uniforms.Eric Anholt2012-12-044-0/+105
| | | | | | | The gen7 send-from-GRF path is sufficiently different from the perspective of IR generation and optimization that I just made it a separate opcode. v2: fix whitespace, rebase on Ken's recent refactor.
* i965/fs: Rename the existing pull constant load opcode.Eric Anholt2012-12-046-14/+16

* i965: Add a header_present flag for setting up dp read messages.Eric Anholt2012-12-043-1/+7
| | | | | | As of gen7, we can skip the header on some messages, and this can make optimization on those messages much nicer when you've got GRFs instead of MRFs as the source.

* mesa: Only require Gen'ed name for glBind{Framebuffer,Renderbuffer} on desktopIan Romanick2012-12-031-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Desktop OpenGL implementations that support either GL_ARB_framebuffer_object or OpenGL 3.0 must require names from glGenFramebuffers for glBindFramebuffer. We have enforced this rule for quite some time. However, OpenGL ES 1.0, 2.0, and 3.0 implementations are required to allow user-defined names (e.g., not from glGenFramebuffers{OES,}). The Intel drivers have hacked around this by not enabling GL_ARB_framebuffer_object in an ES context. Instead, just pick the correct behavior in _mesa_BindFramebuffer based on the context API. Chad pointed out in a review e-mail: "I'd like to point out, though, that glBindFramebufferEXT and glBindRenderbufferEXT are still broken on desktop GL because they don't accept user-genned names. But that fix belongs to a different series." Currently glBindFramebufferEXT is an alias for glBindFramebuffer. Unalising two functions presents some difficulty, so we'll have to revisit this eventually. v2: Perform same check in _mesa_BindRenderbuffer too.

| | | | | | | | | | | | | | | | The NV formulation of primitive restart is turned on/off with glEnableClientState/glDisableClientState. These two functions don't exist in core contexts, which mean that GL_NV_primitive_restart is essentially useless...even broken. However, leaving it on causes oglconform's primitive-restart-nv tests to run in OpenGL 3.1 contexts, which results in them all failing. This patch causes 29 subtests to go from "fail" to "not run".
