2010-10-14glsl: Add support for the 1.30 round() built-in.Kenneth Graunke
This implements round() via the ir_unop_round_even opcode, rather than adding a new opcode. We may wish to add one in the future, since it might enable a small performance increase on some hardware, but for now, this should suffice.
2010-10-14i965: Add support for ir_unop_round_even via the RNDE instruction.Kenneth Graunke
2010-10-14glsl: Add front-end support for GLSL 1.30's roundEven built-in.Kenneth Graunke
Implemented using the op-code introduced in the previous commit.
2010-10-14glsl: Add a new ir_unop_round_even opcode for GLSL 1.30's roundEven.Kenneth Graunke
Also, update ir_to_mesa's "1.30 is unsupported" case to "handle" it.
2010-10-15r300g: clean up warning due to unknown cap.Dave Airlie
2010-10-15r600g: handle absolute modifier in shader translatorKeith Whitwell
This was being classed as unsupported in one place but used in others. Enabling it seems to work fine. Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-10-15r600g: emit hardware linewidthKeith Whitwell
Tested with demos/pixeltest - line rasterization doesn't seem to be set up for GL conventions yet, but at least width is respected now. Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-10-15r600/drm: fix segfaults in winsys create failure pathKeith Whitwell
Would try to destroy radeon->cman, radeon->kman both which were still NULL. Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-10-14i965: Clean up a warning in the old fragment backend.Kenneth Graunke
Hopefully this code can just go away soon.
2010-10-14i965: Enable the new FS backend on pre-gen6 as well.Eric Anholt
It is now to the point where we have no regressing piglit tests. It also fixes Yo Frankie! and Humus DynamicBranching, probably due to the piglit bias tests that work that didn't on the Mesa IR backend. As a downside, performance takes about a 5-10% performance hit at the moment (e.g. nexuiz 19.8fps -> 18.8fps), which I plan to resolve by reintroducing 16-wide fragment shaders where possible. It is a win, though, for fragment shaders using flow control.
2010-10-14i965: Correctly emit the RNDZ instruction.Kenneth Graunke
Simply using RNDU, RNDZ, or RNDE does not produce the desired result. Rather, the RND* instructions place a value in the destination register that may be 1 less than the correct answer. They can also set per-channel "increment bits" in a flag register, which, if set, mean dest needs to be incremented by 1. A second instruction - a predicated add - completes the job. Notably, RNDD always produces the correct answer in a single instruction. Fixes piglit test glsl-fs-trunc.
2010-10-14i965: Use RNDZ for ir_unop_trunc in the new FS.Kenneth Graunke
The existing code used RNDD, which rounds down, rather than toward zero.
2010-10-14glsl: Refresh autogenerated file builtin_function.cpp.Kenneth Graunke
2010-10-14glsl: Add front-end support for the "trunc" built-in.Kenneth Graunke
2010-10-14i965: Use logical-not when emitting ir_unop_ceil.Kenneth Graunke
Fixes piglit test glsl-fs-ceil.
2010-10-14i965: Add peepholing of conditional mod generation from expressions.Eric Anholt
This cuts usually 2 out of 3 instructions for flag reg generation (if statements, conditional assignment) by producing the conditional mod in the expression representing the boolean value. Fixes glsl-fs-vec4-indexing-temp-dst-in-nested-loop-combined (register allocation no longer fails for the conditional generation proliferation)
2010-10-14i965: Add a function for handling the move of boolean values to flag regs.Eric Anholt
This will be a place to peephole comparisions directly to the flag regs, and for now avoids using MOV with conditional mod on gen6, which is now illegal.
2010-10-14Only install vtxfmt tables for OpenGLKristian Høgsberg
GLES1 and GLES2 install their own exec pointers and don't need the Save table. Also, the SET_* macros use different indices for the different APIs so the offsets used in vtxfmt.c are actually wrong for the ES APIs.
2010-10-14i965: Add a pass to the FS to split virtual GRFs to float channels.Eric Anholt
Improves nexuiz performance 0.91% (+/- 0.54%, n=8)
2010-10-14i965: Update the live interval when coalescing regs.Eric Anholt
2010-10-14i965: Set class_sizes[] for the aligned reg pair class.Eric Anholt
So far, I've only seen this be a valgrind warning and not a real failure.
2010-10-14llvmpipe: don't try to emit non-existent color outputsKeith Whitwell
2010-10-14Drop the "neutral" tnl moduleKristian Høgsberg
Just always check for FLUSH_UPDATE_CURRENT and call Driver.BeginVertices when necessary. By using the unlikely() macros, this ends up as a 10% performance improvement (for isosurf, anyway) over the old, complicated function pointer swapping.
2010-10-14st/egl: Do not finish a fence that is NULL.Chia-I Wu
i915g would dereference the NULL pointer.
2010-10-14st/egl: Access _EGLConfig directly.Chia-I Wu
Drop the use of SET_CONFIG_ATTRIB. Fix the value of EGL_SAMPLE_BUFFERS along the way.
2010-10-14egl: Access config attributes directly.Chia-I Wu
Replace SET_CONFIG_ATTRIB/GET_CONFIG_ATTRIB by direct dereferences.
2010-10-14egl: Use attribute names as the _EGLConfig member names.Chia-I Wu
This makes _EGLConfig more accessible and scales better when new attributes are added.
2010-10-14r600g: select linear interpolate if tgsi input requests itDave Airlie

2010-10-14r600g: fixup pos/face ena/address properlyDave Airlie
2010-10-14r600g: only pick centroid coordinate when asked.Dave Airlie
TGSI tells us when to use this, its not hooked up from GLSL to MESA to TGSI yet though.
2010-10-14Revert "i965: fallback lineloop on sandybridge for now"Zhenyu Wang
This reverts commit 73dab75b4165f7d2214a68d4ba8e3cb7aab9b4ac.
2010-10-14i965: Fix GS hang on SandybridgeZhenyu Wang
Don't use r0 for FF_SYNC dest reg on Sandybridge, which would smash FFID field in GS payload, that cause later URB write fail. Also not use r0 in any URB write requiring allocate.
2010-10-13i965: Add support for rescaling GL_TEXTURE_RECTANGLE coords to new FS.Eric Anholt

2010-10-13mesa: Clean up various 'unused parameter' warnings in shaderapiIan Romanick
2010-10-13mesa: Clean up two 'comparison between signed and unsigned' warningsIan Romanick
2010-10-13mesa: Refactor validation of shader targetsIan Romanick
Actually validate that the implementation supports the particular shader target as well. Previously if a driver only supported vertex shaders, for example, glCreateShaderObjectARB would gladly create a fragment shader. NOTE: this is a candidate for the 7.9 branch.
2010-10-13mesa: Silence unused variable warningIan Romanick
2010-10-13linker: Reject shaders that have unresolved function callsIan Romanick
This really amounts to just using the return value from link_function_calls. All the work was being done, but the result was being ignored. Fixes piglit test link-unresolved-funciton. NOTE: this is a candidate for the 7.9 branch.
2010-10-13glsl: Initialize variable in ir_derefence_array::constant_expression_valueVinson Lee
Completely initialize data passed to ir_constant constructor. Fixes piglit glsl-mat-from-int-ctor-03 valgrind uninitialized value error on softpipe.
2010-10-13llvmpipe: Generalize the x8z24 fast path to all depth formats.José Fonseca
Together with the previous commit, this generalize the benefits of d2cf757f44f4ee5554243f3279483a25886d9927 to all depth formats, in particular: - simpler float -> 24unorm conversion - avoid unsigned comparisons (not directly supported on SSE) by aligning to the least significant bit - avoid unecessary/repeated mask ANDing Verified with trivial/tri-z that the exact same assembly is produced for X8Z24.

2010-10-13x11: fix breakage from gl_config::visualType removalBrian Paul
2010-10-13llvmpipe: Unbreak Z32_FLOAT.José Fonseca
Z32_FLOAT uses <4 x float> as intermediate/destination type, instead of <4 x i32>. The necessary bitcasts got removed with commit 5b7eb868fde98388d80601d8dea39e679828f42f Also use depth/stencil type and build contexts consistently, and make the depth pointer argument a ordinary <i8 *>, to catch this sort of issues in the future (and also to pave way for Z16 and Z32_FLOAT_S8_X24 support).
