[Piglit] [PATCH 7/7] arb_enhanced_layouts: More multiple layout qualifiers in a single declaration tests
Andres Gomez
agomez at igalia.com
Sat Oct 22 20:42:26 UTC 2016
Added tests for the layout-qualifier-names "max_vertices",
"invocations", "vertices", "local_size_[x|y|z]" and "xfb_stride" which
may have redeclarations but all of them enforce that a global or
variable redeclaration holds the same value than in the previous
declaration(s).
These tests check that multiple appearances of the same
layout-qualifier-name across multiple layout-qualifiers in the same
declaration with different values won't trigger a compile/link error.
>From the ARB_enhanced_layouts spec:
"More than one layout qualifier may appear in a single declaration.
Additionally, the same layout-qualifier-name can occur multiple times
within a layout qualifier or across multiple layout qualifiers in the
same declaration"
