* glsl: Implement the GLSL 1.30+ discard control flow rule in GLSL IR.Eric Anholt2012-05-144-0/+157
| | | | | | | Previously, I tried implementing this in the i965 driver, but did so in a way that violated the intent of the spec, and broke Tropics. Reviewed-by: Kenneth Graunke <[email protected]>

* glsl: Fix broken constant expression handling for <, <=, >, and >=.Kenneth Graunke2012-05-081-9/+9
| | | | | | | | | | | | | We were looping over all the vector components, but only dealing with the first one. This was masked by the fact that constant expression handling on built-ins went through custom code for the lessThan() /function/ rather than the ir_binop_less expression operator.

* glsl/builtins: Rework profiles to use the new '.glsl' common suffix.Kenneth Graunke2012-04-1720-4807/+1902
| | | | | | | | | | | | | | | | | | | | Deletes a lot of pointless duplication, as well as some run-time effort. Conveniently, GLSL 1.40 no longer needs a .vert variant, since it doesn't define any built-ins specific to the vertex shader stage. ARB_texture_rectangle and OES_EGL_image_external also only need a single profile, since the .vert and .frag variants were identical. I didn't bother with EXT_texture_array and OES_texture_3D because they're so tiny that the savings would be miniscule. Cuts the generated builtin_function.cpp from 1.7MB to 1.0MB (41%).

* glsl/builtins: Support stage-agnostic built-in profiles.Kenneth Graunke2012-04-171-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The built-in subsystem uses "profiles," or GLSL shaders containing prototypes for all built-ins supported within a particular language version (or extension) and shader stage. Since profiles were stage-specific, we had to cut and paste almost all the prototypes between (e.g.) 110.vert and 110.frag. Naturally, this led to sundry cut and paste bugs, where someone fixed an issue in .frag but neglected to update .vert, or vice-versa. Geometry shaders would have only made this worse. This patch introduces support for a new '.glsl' profile suffix which contains prototypes common to all shader stages. The existing '.frag' and '.vert' profiles need only contain the few stage-specific built-ins. Not only does this remove duplication, it makes built-in setup slightly faster: we don't need to re-read the common prototypes and function bodies for both the vertex and fragment shader stage. Internally, this was trivial. We already create a list of gl_shader objects to search through for built-ins: one for the core language version/stage, and additional shaders for any extensions in use. This patch simply adds another shader to the list: core/common, core/stage, and extensions. The next patch will update the profiles to remove the duplication. It's separated out purely to make review easier.

* glsl/builtins: Use ivec for texel offsets in textureProjGradOffset.Kenneth Graunke2012-04-173-4/+4
| | | | | | | | | | | | | | | | | The GLSL 1.30 -> 4.10 specs all erroneously say "vec2" for a few overloads of textureProjGradOffset, while most overloads and all other texturing functions use ivec types. The GLSL 4.20 specification corrects these to "ivec2", but doesn't mention this as being a conscious change in behavior. Nor does the ARB_shading_language_420pack extension. So presumably it was a typo. At any rate, our builtin functions all use ivec already, so the fact that these prototypes use plain vecs will only lead to applications dying in a fire when trying to use them.

* Revert "glsl: Refuse to link GLSL 1.40+ shaders that would use fixed function."Eric Anholt2012-04-161-14/+0
| | | | | | | | | | | | | | | | | | | | | This reverts commit 4ec449a6ed1d2cea3bf83d6518b3b352ce5daceb. I meant to not push this one. Review found that a link error is not mandated: it should link, but you get undefined rendering if you rely on a missing stage. page 42/55 section 2.11 "Vertex Shaders": "If the program object has no vertex shader, or no program object is currently in use, the results of vertex shader execution are undefined." (and similar for page 160/173 section 3.9 "Fragment Shaders" for FS, and page 45/58 section 2.11.2 "Program Objects" for program being 0) It turns out the commit was broken anyway, because it was missing a "goto done", so linkstatus got smashed back to true later and the error just showed up as a warning in the infolog.
