+Subject: [PATCH] Force Glslang to support HLSL in its interface (#784)
+
+Fixes a compilation problem introduced by recent
+Glslang changes to optionally build into a very small
+GLSL-only binary.
+
+Also fix test cases to have set and binding layout qualifiers on
+buffers when compiling for Vulkan.  This rule is now enforced by
+Glslang.

+ The rest of this section describes how to build Shaderc from sources.

++Note: Shaderc assumes Glslang supports HLSL compilation.  The instructions
++below assume you're building Glslang from sources, and in a subtree
++of `shaderc/third_party`.  In that scenario, Glslang's HLSL support
++is automatically enabled.  Shaderc also can be built using a Glslang
++from outside the `shaderc/third_party` tree.  In that case you must
++ensure that that external Glslang is built with HLSL functionality.
++See Glslang's `ENABLE_HLSL` CMake setting.)
