* glsl: remove stage ref generation for transform feedbackTimothy Arceri2015-08-071-6/+4

* glsl: Initialize patch member of glsl_struct_fieldMichel Dänzer2015-08-061-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is apparently a subtle difference in C++ between F f; and F f(); The former will use the default constructor. If there is no default constructor specified, the compiler provides one that simply invokes the default constructor for each field. For built-in basic types, the default constructor does nothing. The later will, according to http://stackoverflow.com/questions/2417065/does-the-default-constructor-initialize-built-in-types) perform value-initialization of the type. For built-in types this means initializing to zero. The per_vertex_accumulator constructor is: per_vertex_accumulator::per_vertex_accumulator() : fields(), num_fields(0) { } This is the second form of constructor, so the glsl_struct_field objects were previously zero initialized. With the addition of an empty default constructor in commit 7ac946e5, per_vertex_accumulator::fields receive no initialization. Fixes a bunch of random (mostly tessellation related) piglit failures since commit 7ac946e5 ("glsl: Add constuctors for the common cases of glsl_struct_field").

| | | | | | | | | | | | | Currently stage reference mask is built using the variable name only. However it can happen that input of one stage has same name as output from another stage.

* glsl: Fix a bug where LHS swizzles of swizzles were too small.Kenneth Graunke2015-07-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A simple shader such as vec4 color; color.xy.x = 1.0; would cause ir_assignment::set_lhs() to generate bogus IR: (swiz xy (swiz x (constant float (1.0)))) We were setting the number of components of each new RHS swizzle based on the highest channel used in the LHS swizzle. So, .xy.y would generate (swiz xy (swiz xx ...)), while .xy.x would break. Our existing Piglit test happened to use .xzy.z, which worked, since 'z' is the third component, resulting in an xxx swizzle. This patch sets the number of swizzle components based on the size of the LHS swizzle's inner value, so we always have the correct number at each step. Fixes new Piglit tests glsl-vs-swizzle-swizzle-lhs-[23]. Fixes ir_validate assertions in in Metro 2033 Redux. v2: Move num_components updating completely out of update_rhs_swizzle (suggested by Timothy Arceri). Simplify.

| | | | | | | | | | | | | | | | | | | | | | | | | | This is the guts of the GLSL parser and AST support for shader subroutines. The code creates a subroutine type in the parser, and uses that there to validate the identifiers. The parser also distinguishes between subroutine types/function prototypes /uniforms and subroutine defintions for functions. Then in the AST conversion it recreates the types, and stores the subroutine definition info or subroutine info into the ir_function along with a side lookup table in the parser state. It also converts subroutine calls into the enhanced ir_call. v2: move to handling method calls in function handling not in field selection. v3: merge Chris's previous parser patches in here, to make it clearer what's changed in one place. v3.1: add more documentation, drop unused include v3.2: drop is_subroutine_def Reviewed-by: Chris Forbes <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
