* glsl: implement switch flow control using a loopTapani Pälli2014-10-201-1/+3
| | | | | | | | | | | | | | | | | | | | | | | Patch removes old variable based logic for handling a break inside switch. Switch is put inside a loop so that existing infrastructure for loop flow control can be used for the switch, now also dead code elimination works properly. Possible 'continue' call inside a switch needs now special handling which is taken care of by detecting continue, breaking out and calling continue for the outside loop. v2: remove one unnecessary ir_expression (Curro) Fixes following Piglit tests: fs-exec-after-break.shader_test fs-conditional-break.shader_test No Piglit or es3conform regressions.

* glsl: Link error if fs defines conflicting qualifiers for gl_FragCoordAnuj Phogat2014-05-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GLSL 1.50 spec says: "If gl_FragCoord is redeclared in any fragment shader in a program, it must be redeclared in all the fragment shaders in that program that have a static use gl_FragCoord. All redeclarations of gl_FragCoord in all fragment shaders in a single program must have the same set of qualifiers." This patch causes the shader link to fail if we have multiple fragment shaders with conflicting layout qualifiers for gl_FragCoord. V2: Restructure the code and add conditions to correctly handle the following case: fragment shader 1: layout(origin_upper_left) in vec4 gl_FragCoord; void main() { foo(); gl_FragColor = gl_FragData; } fragment shader 2: layout(pixel_center_integer) in vec4 gl_FragCoord; void foo() { } V3: Allow linking in the following case: fragment shader 1: void main() { foo(); gl_FragColor = gl_FragCoord; } fragment shader 2: in vec4 gl_FragCoord; void foo() { ... } Signed-off-by: Anuj Phogat <[email protected]> Cc: <[email protected]> Reviewed-by: Ian Romanick <[email protected]>

All redeclarations of gl_FragCoord in all fragment shaders in a single program must have the same set of qualifiers." This patch makes the glsl compiler to generate an error if we have a fragment shader defined with conflicting layout qualifier declarations for gl_FragCoord. For example: layout(origin_upper_left, pixel_center_integer) in vec4 gl_FragCoord; layout(pixel_center_integer) in vec4 gl_FragCoord; void main() { } V2: Some code refactoring for better readability. Add compiler error conditions for redeclarations like: layout(origin_upper_left) in vec4 gl_FragCoord; layout(origin_upper_left, pixel_center_integer) in vec4 gl_FragCoord; and in vec4 gl_FragCoord; layout(origin_upper_left, pixel_center_integer) in vec4 gl_FragCoord; V3: Simplify function is_conflicting_fragcoord_redeclaration() V4: Check for null pointer before doing strcmp(var->name, "gl_FragCoord").

* glsl: convert GS input primitive to use ast_type_qualifierJordan Justen2014-02-201-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | We introduce a new merge_in_qualifier ast_type_qualifier which allows specialized handling of merging input layout qualifiers. By merging layout qualifiers into state->in_qualifier, we allow multiple input qualifiers. For example, the primitive type can be specified specified separately from the invocations count (ARB_gpu_shader5). state->gs_input_prim_type is moved into state->in_qualifier->prim_type state->gs_input_prim_type_specified is still processed separately so we can determine when the input primitive is specified. This is important since certain scenerios are not supported until after the primitive type has been specified in the shader code. v4: * Merge with compute shader input layout qualifiers Signed-off-by: Jordan Justen <[email protected]> Reviewed-by: Anuj Phogat <[email protected]>

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

| | | | | | | | | | | | 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]>

* glsl: Simplify the built-in function linking code.Kenneth Graunke2013-12-011-3/+1
| | | | | | | | | | | | | | | | | | Previously, we stored an array of up to 16 additional shaders to link, as well as a count of how many each shader actually needed. Since the built-in functions rewrite, all the built-ins are stored in a single shader. So all we need is a boolean indicating whether a shader needs to link against built-ins or not. During linking, we can avoid creating the temporary array if none of the shaders being linked need built-ins. Otherwise, it's simply a copy of the array that has one additional element. This is much simpler. This patch saves approximately 128 bytes of memory per gl_shader object. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
