[SPIR-V] Looks like -Fd doesn't work with -spirv

[siliconvoodoo]

I get "Unable to find required part in blob" if I attempt the acrobat move of building with -Zi -Fd -spirv

Thanks for reporting @siliconvoodoo.

@siliconvoodoo Given some differences between dxil and spir-v, I'm somewhat confused about what behavior one might expect from this command line option. Does the file specified by -Fd only contain debug instructions, and nothing else? would that be useful? or would it be generating two output files with the -Fd one having all the SPIR-V binary including the debug info, and the second file (specified with -Fo) having the SPIR-V without any debug instructions?

I agree with your questioning. I was imagining you'd know better than me, but from a very rough mind image I was expecting there may be some sort of DWARF-like format (or whatever) that RenderDoc supports. I guess in the end it's a matter of what debugging tools want as inputs. This could be a case for a discussion with Pix developers. In the meantime you could just implement a hard clear error "not supported"?
