18cfc3f106 For bug #2580: sparseTextureGatherOffsetsARB should only take constant offsets. 2021-03-29 14:27:17 -07:00

89400ea73e GLSL: validation of early_fragment_tests, others, on an object. 
Some layout qualifiers must not be on an object and had a TBD for testing
them: early_fragment_tests, cw/ccw, points, point_mode, and
fractional_even_spacing/fractional_odd_spacing/equal_spacing.

94c18a84cd GLSL: Fix bug setting component=0 for an auto-location assignment. 
Setting component=0 is later taken to mean the shader did so, which
is not always legal. It should instead set the component as not set
by the shader.

8de7e7bf14 GLSL: Error when using location on an arrayed block. 
This implements a recent change to the GLSL specification to enforce
this ill-defined situation.

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.

cc16fa0720 Tests: Move to just linefeed to simply cross-platform test changes. 2015-12-10 18:01:54 -07:00

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.

2b0a11351f Fix two multi-sample bugs: 1) include MS in name mangling, 2) add 'sample' argument texelFetch(*MS*,...). 2015-08-16 21:04:07 -06:00

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.
