* mesa: glsl compiler debug codeBrian Paul2009-01-061-141/+151
| | | | | | RETURN0 macro reports file/line before returning zero. (cherry picked from commit bf7f9d2143a892bc11a5e2b84e3d6d3ed69fb5e8)
* mesa: rework GLSL array code generationBrian Paul2009-01-065-160/+371
| | | | | | | | | | | | | | | | We now express arrays in terms of indirect addressing. For example: dst = a[i]; becomes: MOV dst, TEMP[1 + TEMP[2].y]; At instruction-emit time indirect addressing is converted into ARL/ ADDR-relative form: ARL ADDR.x, TEMP[2].y; MOV dst, TEMP[1 + ADDR.x]; This fixes a number of array-related issues. Arrays of arrays and complex array/struct nesting works now. There may be some regressions, but more work is coming. (cherry picked from commit ae0ff8097b85d3537a7be1674d55a44a9bd6018e)

* mesa: no longer need Writemask field in GLSL IR nodesBrian Paul2009-01-064-69/+23
| | | | | | The Swizzle and Size fields carry all the info we need now. (cherry picked from commit 80d6379722a1249ce13db79a898d340644936f67)
* mesa: revamp GLSL instruction emit codeBrian Paul2009-01-061-244/+381
| | | | | | | | | | | | | | | | | This is a step toward better array handling code. In particular, when more than one operand of an instruction uses indirect addressing, we'll need some temporary instructions and registers. By converting IR storage to instruction operands all in one place (emit_instruction()) we can be smarter about this. Also, somewhat better handling of dst register swizzle/writemask handling. This results in tighter writemasks on some instructions which is good for SOA execution. And, cleaner instruction commenting with inst_comment(). Next: remove some more dead code and additional clean-ups... (cherry picked from commit 3a7ed9779b159f9dccbc98d1d556be2cd83cc1fd)

* mesa: initial support for uniform variable initializers.Brian Paul2009-01-061-5/+22
| | | | | | | This lets one specify initial values for uniforms in the code, avoiding the need to call glUniform() in some cases. (cherry picked from commit 379ff8c9567940ebff44870cf7b0202882445fa6)

* scons: Specify C99 throughout all the tree.José Fonseca2009-01-051-5/+1
| | | | | | | | | | MSVC may not support full C99, but supports more than plain C90. And -pedantic without -std=c99 generates too many spurious warnings (specially C++ style comments) to be of any use. Note that using certain C99 features in the cross-platform parts of Gallium is still not possible; namely mid-of-scope variable declarations and named structure initializers will break MSVC builds.
* gallium: fix two-sided lighting test in state trackerBrian Paul2008-12-181-3/+6

* mesa: choose GLSL vertex shader over ARB/internal vertex program in ↵Brian Paul2008-12-171-1/+13
| | | | | | | | | | | get_fp_input_mask() This is a work-around the for the fact that we do fragment shader state validation before vertex shader validation (see comments in state.c) so in get_fp_input_mask() we can't rely on ctx->VertexProgram._Current being up to date yet. This fixes a glean glsl1 test failure.
* mesa: fix fixed-function test in get_fp_input_mask() - again.Brian Paul2008-12-171-3/+5
| | | | | | The problem we're solving only occured when there was a user-defined vertex shader but no fragment shader. Check for that case now. Fixes glean api2 vertex array failure.

* mesa: fix vertex program test in get_fp_input_mask()Brian Paul2008-12-171-3/+1
| | | | | We were accidentally using the fixed-function logic when a vertex shader was being used.

* gallium: avoid mapping same vertex buffer in subsequent framesKeith Whitwell2008-12-1210-25/+99
| | | | | | | | | | | Quite a few util modules were maintaining a single vertex buffer over multiple frames, and potentially reusing it in subsequent frames. Unfortunately that would force us into syncrhonous rendering as the buffer manager would be forced to wait for the previous rendering to complete prior to allowing the map. This resolves that issue, but requires the state tracker to issue a few new flush() calls at the end of each frame.

* gallium: only mark back color buffer surfaces as undefined after swapbuffersBrian Paul2008-12-101-9/+11
| | | | | Marking all surfaces as undefined was wrong and cause some glean failures because glReadPixels was used after SwapBuffers.
* gallium: fix glBitmap color bugBrian Paul2008-11-261-6/+18
| | | | | | By time we get around to rendering the cached bitmap, the current color may have changed. Need to make sure we load the constant slot with the cached color.

| | | | | | | The clean-up call to pipe->set_vertex_buffers() should use the same number of buffers as the first call. Signed-off-by: Pekka Paalanen <[email protected]>

* mesa: update the shader programs->TexturesUsed array at link timeBrian Paul2008-11-063-4/+26
| | | | | | | | If an application never calls glUniform() to set sampler variable values they'll remain 0 (the default value/unit). Now call _mesa_update_shader_textures_used() at link time in case glUniform() is never called. program->TextureUsed[] will then be correct for state validation.
