API Dump: Feature request, shader output in SPIR-V or even GLSL

[mark-lunarg]

Was surprised to see that selecting the show_shader option in api dump resulted in only the binary data for the shaders being dumped. It'd be super-cool if they'd use SPIRV-Tools to spit out the SPIR-V or GLSL shader source.

I agree, this is a very worthwhile addition. Printing the binary is of limited use since it requires further processing to look at manually. But I don't think GLSL is an appropriate output format since spir-v can contain constructs which don't necessarily map to glsl. Just printing a textual form of spirv would be ideal.

https://github.com/KhronosGroup/SPIRV-Tools would be the candidate library for the disassembler, since its widely used and lightweight.
