| | | | | | | | | | | | | | | | | | | | | This patch adds texture() for isamplerCubeArray and usamplerCubeArray, which were entirely missing. It also makes texture() with a LOD bias fragment shader specific. The main GLSL specification explicitly says that texturing with LOD bias should not be allowed for vertex shaders. Affects Piglit's ARB_texture_cube_map_array/compiler/tex_bias-01.vert. which tries to use bias in a vertex shader. Currently, it expects this to pass (so this patch regresses the test), but I've sent a patch to reverse the expected behavior (so this patch would fix the updated test): http://lists.freedesktop.org/archives/piglit/2013-June/006123.html NOTE: This is a candidate for stable branches.

| | | | | | | | | | | | | | | | | | | | | | | | Many GPUs have an instruction to do linear interpolation which is more efficient than simply performing the algebra necessary (two multiplies, an add, and a subtract). Pattern matching or peepholing this is more desirable, but can be tricky. By using an opcode, we can at least make shaders which use the mix() built-in get the more efficient behavior. Currently, all consumers lower ir_triop_lrp.

* 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.

| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Aside from ir_call, our IR is cleanly split into two classes: - Statements (typeless; used for side effects, control flow) - Values (deeply nestable, pure, typed expression trees) Unfortunately, ir_call confused all this: - For void functions, we placed ir_call directly in the instruction stream, treating it as an untyped statement. Yet, it was a subclass of ir_rvalue, and no other ir_rvalue could be used in this way. - For functions with a return value, ir_call could be placed in arbitrary expression trees. While this fit naturally with the source language, it meant that expressions might not be pure, making it difficult to transform and optimize them. To combat this, we always emitted ir_call directly in the RHS of an ir_assignment, only using a temporary variable in expression trees. Many passes relied on this assumption; the acos and atan built-ins violated it. This patch makes ir_call a statement (ir_instruction) rather than a value (ir_rvalue). Non-void calls now take a ir_dereference of a variable, and store the return value there---effectively a call and assignment rolled into one. They cannot be embedded in expressions. All expression trees are now pure, without exception.
