* glsl: Pass struct shader_compiler_options into do_common_optimization.Kenneth Graunke2013-05-121-1/+3
| | | | | | | | | | | | | do_common_optimization may need to make choices about whether to emit certain kinds of instructions. gl_context::ShaderCompilerOptions contains exactly that information, so it makes sense to pass it in. Rather than passing the whole array, pass the structure for the stage that's currently being worked on.

* glsl: Bump standalone compiler versions to 1.50.Kenneth Graunke2013-03-201-1/+1

* glcpp: Accept pointer to GL context rather than just the API versionCarl Worth2013-01-111-1/+1
| | | | | | | | | As the preprocessor becomes more sophisticated and gains more optional behavior, it's easiest to just pass the GL context pointer to it so that it can examine any fields there that it needs to (such as API version, or the state of any driconf options, etc.).

* glsl: Create builtin function profiles for GLSL 3.00 ES.Paul Berry2012-12-061-0/+1
| | | | | | | | | | | | | | | | Nearly all of the builtin functions in GLSL 3.00 ES are already implemented in Mesa; this patch enables them. A few functions are not implemented yet; those have been commented out, with a FIXME comment to act as a reminder of what still needs to be implemented. Here is the complete list: packSnorm2x16, unpackSnorm2x16, packUnorm2x16, unpackUnorm2x16, packHalf2x16, unpackHalf2x16.

* glsl: Record in gl_shader whether the shader uses GLSL ES.Paul Berry2012-12-061-0/+1
| | | | | | | | | | | | | | | | | | Previously we recorded just the GLSL version, with the knowledge that 100 means GLSL 1.00 ES. With the advent of GLSL 3.00 ES, this is going to get more complex, and eventually will probably become ambiguous (GLSL 4.00 already exists, and GLSL 4.00 ES is likely to be created some day). To reduce confusion, this patch simply records whether the shader is GLSL ES as an explicit boolean. [v2, idr]: s/IsEs(Shader|Prog)/IsES/ Suggested by Ken and Eric.

* glsl: Add uniform_locations_assigned parameter to do_dead_code opt passIan Romanick2011-10-251-1/+1
| | | | | | | | | | | | | | | | | Setting this flag prevents declarations of uniforms from being removed from the IR. Since the IR is directly used by several API functions that query uniforms in shaders, uniform declarations cannot be removed after the locations have been set. However, it should still be safe to reorder the declarations (this is not tested).

* mesa: Ensure that gl_shader_program::InfoLog is never NULLIan Romanick2011-08-021-0/+1
| | | | | | | | | | | | | | | | This prevents assertion failures in ralloc_strcat. The ralloc_free in _mesa_free_shader_program_data can be omitted because freeing the gl_shader_program in _mesa_delete_shader_program will take care of this automatically. A bunch of this code could use a refactor to use ralloc a bit more effectively. A bunch of the things that are allocated with malloc and owned by the gl_shader_program should be allocated with ralloc (using the gl_shader_program as the context).

* glsl: Move functions into standalone_scaffolding.cpp for later reuse.Paul Berry2011-07-221-57/+3
| | | | | | | | | | | | | | | | This patch moves the following functions from main.cpp (the main cpp file for the standalone executable that is used to create the built-in functions) to standalone_scaffolding.cpp, so that they can be re-used in other standalone executables: - initialize_context()* - _mesa_new_shader() - _mesa_reference_shader() *initialize_context contained some code that was specific to main.cpp, so it was split into two functions: initialize_context() (which remains in main.cpp), and initialize_context_from_defaults() (which is in standalone_scaffolding.cpp).
* glsl: Flagged extension EXT_texture3D as "supported" in the builtin compiler.Paul Berry2011-06-231-0/+1
| | | | | | | Previously, the builtins in OES_texture_3D.{frag,vert} were only compiling properly as a consequence of bug 38015, which allows unsupported extensions to be enabled. This fix eliminates the builtin compiler's reliance on bug 38015, so that bug 38015 can be fixed.

| | | | | | | | | | | | | | | | | The new usage message lists possible command line options.

Example Output -------------- usage: ./glsl_compiler [options] <file.vert | file.geom | file.frag> Possible options are: --glsl-es --dump-ast --dump-hir --dump-lir --link
* glsl: Slightly change the semantic of _LinkedShadersIan Romanick2010-10-141-1/+12
| | | | | | | | | | | | | | | Previously _LinkedShaders was a compact array of the linked shaders for each shader stage. Now it is arranged such that each slot, indexed by the MESA_SHADER_* defines, refers to a specific shader stage. As a result, some slots will be NULL. This makes things a little more complex in the linker, but it simplifies things in other places. As a side effect _NumLinkedShaders is removed. NOTE: This may be a candidate for the 7.9 branch. If there are other patches that get backported to 7.9 that use _LinkedShader, this patch should be cherry picked also.

| | | | | | | | Whereas constant folding evaluates constant expressions at rvalue nodes, constant propagation tracks constant components of vectors across execution to replace (possibly swizzled) variable dereferences with constant values, triggering possible constant folding or reduced variable liveness.

* linker: Link built-in functions instead of including them in every shaderIan Romanick2010-07-211-0/+4
| | | | | | | | This is an invasive set of changes. Each user shader tracks a set of other shaders that contain built-in functions. During compilation, function prototypes are imported from these shaders. During linking, the shaders are linked with these built-in-function shaders just like with any other shader.
