* glsl: Support transform feedback of varying structs.Paul Berry2013-02-042-67/+184
| | | | | | | | | | | | | | | | | | | Since transform feedback needs to be able to access individual fields of varying structs, we can no longer match up the arguments to glTransformFeedbackVaryings() with variables in the vertex shader. Instead, we build up a hashtable which records information about each possible name that is a candidate for transform feedback, and then match up the arguments to glTransformFeedbackVaryings() with the contents of that hashtable. Populating the hashtable uses the program_resource_visitor infrastructure, so the logic is shared with how we handle uniforms. NOTE: This is a candidate for the 9.1 branch.

* glsl: Use parse_program_resource_name to parse transform feedback varyings.Paul Berry2013-02-042-19/+16
| | | | | | | | | | | | | | | | | | | Previously, transform feedback varyings were parsed in an ad-hoc fashion that wasn't compatible with structs (or array of structs). This patch makes it use parse_program_resource_name(), which correctly handles both. Note that parse_program_resource_name()'s technique for handling mal-formed input strings is to simply let them through and rely on the fact that a future name lookup will fail. Because of this, tfeedback_decl::init() no longer needs to return a boolean error code--it always succeeds, and if the input was mal-formed the error will be detected later.

* glsl: Rename uniform_field_visitor to program_resource_visitor.Paul Berry2013-02-044-33/+34
| | | | | | | | | | | | | | | | There's actually nothing uniform-specific in uniform_field_visitor. It is potentially useful for all kinds of program resources (in particular, future patches will use it for transform feedback varyings). This patch renames it to program_resource_visitor, and clarifies several comments, to reflect the fact that it is useful for more than just uniforms. NOTE: This is a candidate for the 9.1 branch.

* mesa/glsl: Separate parsing logic from _mesa_get_uniform_location.Paul Berry2013-02-044-61/+91
| | | | | | | | | | | | | | | | The parsing logic is moved to a new function in the GLSL module, parse_program_resource_name(). This name was chosen because it should eventually be useful for handling everything that OpenGL 4.3 calls "program resources" (e.g. uniforms, vertex inputs, fragment outputs, and transform feedback varyings). Future patches will make use of this function for linking transform feedback varyings. NOTE: This is a candidate for the 9.1 branch.

* builtin_compiler/build: Don't use *_FOR_BUILD when not cross compilingMatt Turner2013-02-041-11/+32
| | | | | | | | | | | | | | | | | | | | | | | | | Previously we were relying on CFLAGS_FOR_BUILD to be the same as CFLAGS when not cross compiling, but this assumption didn't take into consideration 32-bit builds on 64-bit systems. More generally, not honoring CFLAGS is bad. Automake is evidently too stupid to accept if CROSS_COMPILING CC = @CC_FOR_BUILD@ ... else CC = @CC@ endif without warning that CC has been already defined. The warnings are harmless, but I'd prefer to avoid future reports about them, so define proxy variables, which are assigned inside the conditional and then unconditionally assigned to CC et al.

|
* gallium: add SQRT shader opcodeBrian Paul2013-02-043-2/+12
| | | | | | | | | | | | | | | | | | The glsl-to-tgsi translater will emit SQRT to implement GLSL's sqrt() and distance() functions if the PIPE_SHADER_CAP_TGSI_SQRT_SUPPORTED query says it's supported by the driver. Otherwise, sqrt(x) is implemented with x*rsq(x). The problem with this is sqrt(0) must be handled specially because rsq(0) might be Inf/NaN/undefined (and then 0*rsq(0) is Inf/Nan/undefined). In the glsl-to-tgsi code we use an extra CMP to check if x is zero and then replace the result of x*rsq(x) with zero. In the end, this makes sqrt() generate much more reasonable code for drivers that can do square roots. Note that many of piglit's generated shader tests use the GLSL distance() function.

* st/mesa: don't choose DXT formats if we can't do DXT compressionBrian Paul2013-02-045-13/+29
| | | | | | | | | | | | | | | | | | | | If we call gl[Copy]TexImage2D() with a generic compression format (e.g. intFormat=GL_COMPRESSED_RGBA) we can't choose a DXT format if we don't have the external DXT compression library. We weren't actually enforcing this before since the pipe_screen::is_format_supported(DXT) query has no dependency on the DXT compression library. Now if we're given a generic compressed format and we can't do DXT compression we'll fall back to a non-compressed format. v2: use util_format_is_s3tc() function and add more comments about the allow_dxt parameter.

* i965: Fix the SF Vertex URB Read Length calculation for Gen7 platforms.Kenneth Graunke2013-02-031-16/+16
| | | | | | | | | | | | | | | | | | | Ivybridge doesn't appear to have the same errata as Sandybridge; no corruption was observed by setting it to more than the minimal correct value. It's possible that we were simply lucky, since the URB entries are 1024-bit on Ivybridge vs. 512-bit Sandybridge. Or perhaps the underlying hardware issue is fixed. Either way, we may as well program the minimum value since it's now readily available, likely to be more efficient, and possibly more correct. v2: Use GEN7_SBE_* defines rather than GEN6_SF_*. (A copy and paste mistake.) They're the same, but using the right names is better. NOTE: This is a candidate for all stable branches.

* i965: Fix the SF Vertex URB Read Length calculation for Sandybridge.Kenneth Graunke2013-02-031-16/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (This commit message was primarily written by Paul Berry, who explained what's going on far better than I would have.) Previous to this patch, we thought that the only restrictions on 3DSTATE_SF's URB read length were (a) it needs to be large enough to read all the VUE data that the SF needs, and (b) it can't be so large that it tries to read VUE data that doesn't exist. Since the VUE map already tells us how much VUE data exists, we didn't bother worrying about restriction (a); we just did the easy thing and programmed the read length to satisfy restriction (b). However, we didn't notice this erratum in the hardware docs: "[errata] Corruption/Hang possible if length programmed larger than recommended". Judging by the context surrounding this erratum, it's pretty clear that it means "URB read length must be exactly the size necessary to read all the VUE data that the SF needs, and no larger". Which means that we can't program the read length based on restriction (b)--we have to program it based on restriction (a). The URB read size needs to precisely match the amount of data that the SF consumes; it doesn't work to simply base it on the size of the VUE. Thankfully, the PRM contains the precise formula the hardware expects. Fixes random UI corruption in Steam's "Big Picture Mode", random terrain corruption in PlaneShift, and Piglit's fbo-5-varyings test. NOTE: This is a candidate for all stable branches.
