[Piglit] [PATCH 4/9] arb_shading_language_420pack: More multiple layout qualifiers in a single declaration tests
Andres Gomez
agomez at igalia.com
Wed Oct 26 16:14:11 UTC 2016
Added tests for the layout-qualifier-names "max_vertices",
"invocations", "vertices" and "local_size_[x|y|z]" which may have
redeclarations but all of them enforce that a redeclaration holds the
same value than in the previous declaration(s).
These tests check that multiple appearances of a layout-qualifier-name
across different layout qualifiers with different values in the same
declaration won't trigger a compile/link error.
>From the ARB_shading_language_420pack spec:
"More than one layout qualifier may appear in a single declaration. If
the same layout-qualifier-name occurs in multiple layout qualifiers for
the same declaration, the last one overrides the former ones."
V2: Removed link check, as suggested by Timothy.
