Hello,
I’ve started testing the Metal Shader Converter to convert my HLSL shaders to metallib directly, and I was wondering if the option ’-frecord-sources’ was supported in any way?
Usually I’m compiling my shaders as follows (from Metal):
xcrun -sdk macosx metal -c -frecord-sources shaders/shaders.metal -o shaders/shaders.air
xcrun -sdk macosx metallib shaders/shaders.air -o shaders/shaders.metallib
The -frecord-sources allow me to see the source when debugging and profiling a Metal frame.
Now with DXC we have a similar option, I can compile a typical HLSL shader with embedded debug symbols with:
dxc -T vs_6_0 -E VSMain shaders/triangle.hlsl -Fo shaders/triangle.dxil -Zi -O0 -Qembed_debug
The important options here are ’-Zi` and ’-Qembed_debug’, as they make sure debug symbols are embedded in the DXIL.
It seems that right now Metal Shader Converter doesn’t pass through the DXIL debug information, and I was wondering if it was possible. I’ve looked at all the options in the utility and haven’t seen anything that looked like it.
Right now debug symbols in my shaders is a must-have, so I’ll explore other routes to convert my HLSL shaders to Metal (I’ve been testing spir-v cross to do the conversion, I haven’t actually tested the debug symbols yet, I’ll report back later).
Thank you for your time!
