* mesa: Use gl_shader::Stage instead of gl_shader::Type where possible.Paul Berry2014-01-082-14/+18
| | | | | | | | | | | | | | | | | | | | | This reduces confusion since gl_shader::Type is sometimes GL_SHADER_PROGRAM_MESA but is more frequently GL_SHADER_{VERTEX,GEOMETRY,FRAGMENT}. It also has the advantage that when switching on gl_shader::Stage, the compiler will alert if one of the possible enum types is unhandled. Finally, many functions in src/glsl (especially those dealing with linking) already use gl_shader_stage to represent pipeline stages; using gl_shader::Stage in those functions avoids the need for a conversion. Note: in the process I changed _mesa_write_shader_to_file() so that if it encounters an unexpected shader stage, it will use a file suffix of "????" rather than "geom".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we had an enum called gl_shader_type which represented pipeline stages in the order they occur in the pipeline (i.e. MESA_SHADER_VERTEX=0, MESA_SHADER_GEOMETRY=1, etc), and several inconsistently named functions for converting between it and other representations: - _mesa_shader_type_to_string: gl_shader_type -> string - _mesa_shader_type_to_index: GLenum (GL_*_SHADER) -> gl_shader_type - _mesa_program_target_to_index: GLenum (GL_*_PROGRAM) -> gl_shader_type - _mesa_shader_enum_to_string: GLenum (GL_*_{SHADER,PROGRAM}) -> string This patch tries to clean things up so that we use more consistent terminology: the enum is now called gl_shader_stage (to emphasize that it is in the order of pipeline stages), and the conversion functions are: - _mesa_shader_stage_to_string: gl_shader_stage -> string - _mesa_shader_enum_to_shader_stage: GLenum (GL_*_SHADER) -> gl_shader_stage - _mesa_program_enum_to_shader_stage: GLenum (GL_*_PROGRAM) -> gl_shader_stage - _mesa_progshader_enum_to_string: GLenum (GL_*_{SHADER,PROGRAM}) -> string In addition, MESA_SHADER_TYPES has been renamed to MESA_SHADER_STAGES, for consistency with the new name for the enum.

* Rename overloads of _mesa_glsl_shader_target_name().Paul Berry2013-12-301-1/+1
| | | | | | | | | | | | Previously, _mesa_glsl_shader_target_name() had an overload for GLenum and an overload for the gl_shader_type enum, each of which behaved differently. However, since GLenum is a synonym for unsigned int, and unsigned ints are often used in place of gl_shader_type (e.g. in loop indices), there was a big risk of calling the wrong overload by mistake. This patch gives the two overloads different names so that it's always clear which one we mean to call. Reviewed-by: Brian Paul <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, all of the back-ends (ir_to_mesa, st_glsl_to_tgsi, and the i965 fs and vec4 visitors) had nearly identical logic for handling bounded loops. This replaces the duplicate logic with an equivalent lowering pass that is used by all the back-ends. Note: on i965, there is a slight increase in instruction count. For example, a loop like this: for (int i = 0; i < 100; i++) { total += i; } would previously compile down to this (vec4) native code: mov(8) g4<1>.xD 0D mov(8) g8<1>.xD 0D loop: cmp.ge.f0(8) null g8<4;4,1>.xD 100D (+f0) break(8) add(8) g5<1>.xD g5<4;4,1>.xD g4<4;4,1>.xD add(8) g8<1>.xD g8<4;4,1>.xD 1D add(8) g4<1>.xD g4<4;4,1>.xD 1D while(8) loop After this patch, the "(+f0) break(8)" turns into: (+f0) if(8) break(8) endif(8) because the back-end isn't smart enough to recognize that "if (condition) break;" can be done using a conditional break instruction. However, it should be relatively easy for a future peephole optimization to properly optimize this. Reviewed-by: Jordan Justen <[email protected]> Reviewed-by: Ian Romanick <[email protected]>

| | | | | | | | | | | | | | | | | | | i965 passed piglit, but swrast and gallium both segfaulted without this. i965 happened to work because it never ran _mesa_load_state_parameters() on the new program before the test called glProgramLocalParameter(), which was allocating a LocalParams array for the fallback path. v2: Since v1 threw away old localparams data, leaked old LocalParams memory, only fixed fragment programs, and I was dubious of my previous invariants already (nothing but program_parse.y will generate LocalParams, and only that one path of program_parse.y will), just late-allocate localparams at the other point of dereferencing them. This adds overhead to _mesa_load_state_parameter, which is uncomfortable, but I'm pretty sure that giant switch statement is super slow already.

| | | | | | | | | | | | | | | | | | | | | | | During compilation, we'll use this to determine built-in availability. The plan is to have a single shader containing every built-in in every version of the language, but filter out the ones that aren't actually available to the shader being compiled. At link time, we don't actually need this filtering capability: we've already imported prototypes for every built-in that the shader actually calls, and they're flagged as is_builtin(). The linker doesn't import any additional prototypes, so it won't pull in any unavailable built-ins. When resolving prototypes to function definitions, the linker ensures the values of is_builtin() match, which means that a shader can't trick the linker into importing the body of an unavailable built-in by defining a suspiciously similar prototype. In other words, during linking, we can just pass in NULL. It will work out fine.
