%description devel
glslang is the official reference compiler front end for the OpenGL
ES and OpenGL shading languages. It implements a strict
interpretation of the specifications for these languages.

spirv-remap is a utility to improve compression of SPIR-V binary
files via entropy reduction, plus optional stripping of debug
information and load/store optimization. It transforms SPIR-V to
SPIR-V, remapping IDs. The resulting modules have an increased ID
range (IDs are not as tightly packed around zero), but will compress
better when multiple modules are compressed together, since
compressor's dictionary can find better cross module commonality.
