Subject: glsl: inspect interfaces in contains_foo()
X-Git-Tag: upstream/17.1.0~5149
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5d83820a1d4f6b2390520d2335848d351db13fd7;p=platform%2Fupstream%2Fmesa.git

glsl: inspect interfaces in contains_foo()

When checking if a type contains doubles, integers, samples, etc. we
check if the current type is a record or array, but not if it is an
interface.

This commit also inspects if the type is an interface.

It fixes spec/arb_enhanced_layouts/compiler/transform-feedback-layout-qualifiers/xfb_offset/invalid-block-with-double.vert
piglit test.
