1c3ab274b1 Test Results Only: Include size in implicitly sized arrays (change to unsized). 
This effects 60 tests, in a trivial way, but is critical to factor out this
noise from future planned changes.

e00e8f45a6 GLSL: replace general missing functionality with specific messages. 2017-06-05 16:42:33 -06:00

71c100d7c0 GLSL output: Removed fixed-size buffer; fixes #769. 
Makes some white-space differences in most output, plus a few cases
where more could have been put out but was cut short by the previous
fix-sized buffer.

906cc21816 Linker: Eliminate uncalled functions, because they can be ill-defined. 
Fixes issue #610. Also provides a testing option to keep uncalled functions.

6fccb3cd75 Non-functional: Sweep through the stack for consistent with "main" and entry point. 
Partially addresses issue #513.

61d9fb9048 Semantics: 'invocations' defaults to 1, not 0. 
'invocations' was using 0 as the "shader never set" flag and as the
default. Formalize this and explicit set to 1 and link time.

494a02a2b0 Semantics: Geometry stage can support max_vertices = 0. 
To do this, more generally use a named -1 as a not set value.

fc51d284aa Backward incompatible: Turn on PureOperatorBuiltins: use only enum-based built-in functions in the AST. 
If this breaks your AST consumer, best is to modify it to test
against the enum values instead of doing string comparisons on
built-in function names.  This is the reason the change was made.

If you need the old behavior, you should be able to get it back by changing
PureOperatorBuiltins to be false instead of true.  This path will work for
a while, but is marked deprecated.

Also, the old behavior is tagged as release 2.4.

dff18a2be0 glslang: Formally track all built-in variables, right from the beginning, to enable avoiding all textual compares at any subsequent stage in the stack. (To be used in future check ins.)

8b37b04ecc glslang AST output: include global vs. temp (local) in the printed output. This only effects test results, but a future check-in is going to fix some globals.

cf0206c341 Restore r26245 and all tests and test results since 4/1: 
r26245: Remove "not yet complete" warning for versions 130 and 140, after tidying up a bit and adding tests.  Token pasting is the only known missing feature, and gives its own message now on use.

f2d042a1fe Non-functional, infrastructure: Be more explicit about "implicit array sizes", improving the infrastructure for handling them. Also fix some output that was too big for its buffer. 
There is more upcoming functionality for link-time sizing of implicitly-sized arrays that will use this.

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.

7cbfdf4394 Minor infrastructure changes, to simplify an upcoming check in: 
- print out block member types when printing a block (makes all test results change)
 - const versions of all intermediate.h type-identification methods
 - layoutSlotLocation -> layoutLocation

7c908d2543 Additional semantic checking for tessellation shaders and related clean up: 
- 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

623833fabc Tessellation partial implementation (not ready for use yet), including: 
- the built-in constants
 - built-in variable declarations, some dependent on gl_MaxPatchVertices
 - layout qualifier for vertices (shared with geometry shader max_vertices)
 - layout qualifiers for vertex spacing, vertex order, point mode, and primitive type
 - link semantics for layout qualifiers

Still TBD:
 - patch qualifier and arrayed input handling
 - sizing of gl_out[]
 - additional semantic checking
 - supporting the extension on version 150

c719481d43 Flesh out 4.x block redeclaration semantics: 
- hide non-redeclared anonymous members
 - array size limit checking
 - illegal member qualifiers
 - additional members

5134b9cf57 Track what ins/outs/uniforms are used, so that errors like "declare after use" or "can't use both XXX and YYY" can be issued. So far, used this for invariant, gl_FragColor et. al., and gl_FragCoord use before redeclaration. 
Also made all tests in testlist include linker tests.
