From: Xiang Li Date: Thu, 5 May 2022 22:31:22 +0000 (-0700) Subject: [HLSL] Enable vector types for hlsl. X-Git-Tag: upstream/15.0.7~6382 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e576280380d3f5221cfcc14e9fabeacc8506a43c;p=platform%2Fupstream%2Fllvm.git [HLSL] Enable vector types for hlsl. Vector types in hlsl is using clang ext_vector_type. Declaration of vector types is in builtin header hlsl.h. hlsl.h will be included by default for hlsl shader.
