* glsl: make builtin_mem_ctx a staticDave Airlie2012-09-151-1/+1

* glsl: Scaffolding for ARB_shader_bit_encoding.Olivier Galibert2012-06-071-0/+1
| | | | | | | | That adds support for activating the extension. It doesn't actually *do* anything yet, of course. Signed-off-by: Olivier Galibert <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>
* glsl/builtins: Fix textureGrad() for Array samplers.Kenneth Graunke2012-06-051-3/+3
| | | | | | | | | | | | We were incorrectly assuming that the coordinate's dimensionality is equal to the gradient's dimensionality. For array types, the coordinate has one more component. Fixes 12 subcases of oglconform's glsl-bif-tex-grad test. NOTE: This is a candidate for stable release branches. Signed-off-by: Kenneth Graunke <[email protected]>
* glsl: Add support for generating builtin code from GLSL instead of IR.Eric Anholt2012-04-241-4/+16
| | | | | | | | This takes advantage of the builtin compiler to generate IR into a string, the same way we read GLSL for function prototypes for our profiles. Reviewed-by: Kenneth Graunke <[email protected]>
* 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: Add remaining *sampler2DRect* texture functions.Eric Anholt2012-04-161-0/+22
| | | | | | Fixes the new piglit texelFetch() tests on these. Note that the rest of the new functions are not tested (same as the non-2DRect versions of most of them).

* glsl: Don't apply optimization passes to builtins.Eric Anholt2012-04-111-1/+1
| | | | | | The builtins we have are generally optimized, having been hand-written. This avoids generating bad code when an optimization pass prints debug output.
* glsl: Add texelFetch(*samplerBuffer) entrypoints to GLSL 1.40.Eric Anholt2012-04-091-4/+7
| | | | | | | | Fix texelFetch(sampler2DRect) and textureSize(samplerBuffer) generation to not reference a LOD at the same time because it's easier than not fixing it. Reviewed-by: Kenneth Graunke <[email protected]>
* glsl: initialise const force glsl extension warning in fake ctxDave Airlie2012-03-251-0/+1
| | | | | | | | | valgrind complained about an uninitialised value being used in glsl_parser_extras.cpp, and this was the one it was giving out about. Just initialise the value in the fakectx. Signed-off-by: Dave Airlie <[email protected]>
* glsl: Add GLSL 1.40 textureSize() implementations for sampler2DRect.Eric Anholt2012-03-151-2/+9
| | | | | | | | | | | | | By setting lod to 0 in the builtin function implementation, we avoid needing to update all the visitors to ignore LOD in this case, when the hardware drivers actually want to ask for LOD 0 for rectangular textures. Fixes piglit spec/GLSL-1.40/textureSize-*Rect. v2: Change style of looking for substrings. Reviewed-by: Kenneth Graunke <[email protected]>
* glsl: Set up generated builtin functions handling for GLSL 1.40.Eric Anholt2012-03-151-3/+3

* glsl: When failing to compile some builtins, print the error.Eric Anholt2012-03-151-0/+8

| | | | | | | | | These simply don't exist in the 1.30 specification---none of the Offset variants allow samplerCube.

* glsl: Add '.ir' extension to builtin IR filesPaul Berry2011-10-311-3/+9
| | | | | | | | This patch adds the extension '.ir' to all the files in src/glsl/builtins/ir/, and changes generate_builtins.py so that it no longer globs on '*' to find the files to build. This prevents spurious files (such as EMACS' infamous *~ backup files) from breaking the build.
* glsl: Defer initialization of built-in functions until they're needed.Kenneth Graunke2011-09-231-2/+4
| | | | | | | | | | | | | | | Very simple shaders don't actually use GLSL built-ins. For example: - gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex; - gl_FragColor = vec4(0.0); Both of the shaders used by _mesa_meta_glsl_Clear() also qualify. By waiting to initialize the built-ins until the first time we need to look for a signature, we can avoid the overhead entirely in these cases. Makes piglit run roughly 18% faster (255 vs. 312 seconds). Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Eric Anholt <[email protected]>

* glsl: Explicitly specify a type when reading/printing ir_texture.Kenneth Graunke2011-03-141-5/+6
| | | | | | This is necessary for GLSL 1.30+ shadow sampling functions, which return a single float rather than splatting the value to a vec4 based on GL_DEPTH_TEXTURE_MODE.

* glsl: Fix use of uninitialized values in _mesa_glsl_parse_state ctor.Kenneth Graunke2011-02-011-0/+2
| | | | | | This has probably existed since e5e34ab18eeaffa465 or so. NOTE: This is a candidate for the 7.9 and 7.10 branches.

|
* texture_builtins.py: Generalize the "use_proj" field to support offsets.Kenneth Graunke2011-01-311-52/+57
| | | | | | | | Rather than passing "True", pass a bitfield describing the particular variant's features - either projection or offset. This should make the code a bit more readable ("Proj" instead of "True") and make it easier to support offsets in the future.
* texture_builtins.py: Refactor coordinate dimension calculations.Kenneth Graunke2011-01-311-5/+9
| | | | | For offsets, we'll want the straight sampler dimensionality, without the +1 for array types. Create a new function to do that; refactor.
* glsl: Change texel offsets to a single vector rvalue.Kenneth Graunke2011-01-311-1/+1
| | | | | | | | | | | Having these as actual integer values makes it difficult to implement the texture*Offset built-in functions, since the offset is actually a function parameter (which doesn't have a constant value). The original rationale was that some hardware needs these offset baked into the instruction opcode. However, at least i965 should be able to support non-constant offsets. Others should be able to rely on inlining and constant propagation.

| | | | | | Python is already necessary for other parts of Mesa, so there's no reason we can't just generate it. This patch updates both make and SCons to do so.
* glsl: Really remove unused "instructions" parameter.Kenneth Graunke2011-01-011-2/+1
| | | | | I forgot about this file, and it didn't show up until I tried to do "make builtins" from a clean build.
* glsl: Remove unused "instructions" parameter.Kenneth Graunke2011-01-011-4/+2
| | | | | | I think was used long ago, when we actually read the builtins into the shader's instruction stream directly, rather than creating a separate shader and linking the two. It doesn't seem to serve any purpose now.
* glsl: Lazily import built-in function prototypes.Kenneth Graunke2010-11-301-1/+0
| | | | | | | | This makes a very simple 1.30 shader go from 196k of memory to 9k. NOTE: This -may- be a candidate for the 7.9 branch, as the benefit is substantial. However, it's not a simple change, so it may be wiser to wait for 7.10.

* generate_builtins.py: Output large strings as arrays of characters.Kenneth Graunke2010-10-211-2/+14
| | | | | | This works around MSVC's 65535 byte limit, unfortunately at the expense of any semblance of readability and much larger file size. Hopefully I can implement a better solution later, but for now this fixes the build.

* glsl2: Clear out profile pointers in _mesa_glsl_release_functionsIan Romanick2010-09-081-0/+1
| | | | | | Otherwise builtin_profiles contains dangling pointers the next time _mesa_read_profile is called. I suspect this may fix bugzilla #29847, but I was never able to reproduce it.
* glsl2: Make sure _mesa_glsl_parse_state constructor gets a contextIan Romanick2010-09-081-1/+2

* glsl: Clear the static values of builtin function profiles at release.Eric Anholt2010-08-301-19/+37
| | | | | | | When releasing the builtin functions, we were just freeing the memory, not telling the builtin function loader that we had freed its memory. I wish I had done ARB_ES2_compatibility so we had regression testing of this path. Fixes segfault on changing video options in nexuiz.
* glsl: Protect against double compiler-destroy.Eric Anholt2010-08-271-0/+1
| | | | | DRI was doing teardown when we close the last screen, then an atexit() was added to call it as well.
* glsl: Use a single shared namespace in the symbol table.Kenneth Graunke2010-08-261-0/+1
| | | | | | | | | | | | As of 1.20, variable names, function names, and structure type names all share a single namespace, and should conflict with one another in the same scope, or hide each other in nested scopes. However, in 1.10, variables and functions can share the same name in the same scope. Structure types, however, conflict with/hide both. Fixes piglit tests redeclaration-06.vert, redeclaration-11.vert, redeclaration-19.vert, and struct-05.vert.
