b10feabc95 Front-end: Non-functional: Move return-value handling from .y to .cpp.
This is to make the real change needed in the next commit easier.

d94c003fb7 Front-end: Complete GL_ARB_compute_shader implementation.
Core compute shaders were working, but the extension wasn't implemented.

eb505e4262 Allow future keywords to be accessed as members in a struct.
This fixes a bug where a token that could be a keyword in one version
is not a keyword in another version, but treated like a non-member after
a "." dereference.

9312269d09 Front-end Arrays of arrays: Add ES-specific checks and tests. AoA should be quite close to done now. 2015-09-11 15:25:38 -06:00

65c78a0b62 Array of array: Implement the core functionality: types, constructors, operations.
There will be subsequent commits to refine semantics, esp. version-specific semantics,
as well as I/O functionality and restrictions.

Note: I'm getting white-space differences in the preprocessor test results,
which I'm not checking in.  I think they need to be tagged as binary or something.

93deac5295 Fix incompatibility with <GL/glext.h>
New extensions in glext.h follow the pattern:

    #ifndef GL_ARB_texture_rectangle
    #define GL_ARB_texture_rectangle 1
    #define GL_TEXTURE_RECTANGLE_ARB          0x84F5
    #define GL_TEXTURE_BINDING_RECTANGLE_ARB  0x84F6
    #define GL_PROXY_TEXTURE_RECTANGLE_ARB    0x84F7
    #define GL_MAX_RECTANGLE_TEXTURE_SIZE_ARB 0x84F8
    #endif /* GL_ARB_texture_rectangle */

Versions.h tries to declare:

    const char* const GL_ARB_texture_rectangle = "GL_ARB_texture_rectangle";

Which means, if you've included glext.h before Versions.h, that the
compiler will see "const char* const 1 = ...", and rightly refuse to
continue.

The ham-fisted approach taken here is to rename the variables in
Versions.h with a leading underscore.  This does sort of undermine the
comment about "better to have the compiler do spelling checks", but.

5053a39578 Fix slight inconsistencies in which qualifiers are inherited into block members:
- don't inherit 'binding'
 - always set the member storage qualifier, not just when the shader explicitly set it
 - don't include in/out members as objects that are resized by geometry/primitive layout specifiers
As a side effect, this makes built-in redeclarations (like gl_ClipDistance) require in/out.

- non-arrayed geometry inputs and tessellation-control outputs
 - include user blocks in i/o array resizing based on primitive type
 - things belonging only to 'in' or 'out' are verified only on 'in' or 'out'
 - invocation number changing
 - move shader-scoped qualifier checking into its class
 - remove an incidental union of two levels of the node hierarchy in the yacc stack
 - remove layout(location=) default tracking when setting on a variable
