Is easier to read code generation possible for non-SPIRV targets?

[track3r]

For example, currently looking at generated HLSL and GLSL code, I see that a lot of unnecessary variables are being introduced. It's great that they retain original variable name as a prefix but still could be quite hard to read while debugging shaders on some special platforms. Would it be even possible to support leaner output?

Hi @track3r ,

Have you tried these options?
-no-mangle: Do as little mangling of names as possible.
-O0, -Onone: Disable all optimizations
-no-hlsl-pack-constant-buffer-elements: Do not pack elements of constant buffers into structs in the output HLSL code.

maybe worthing trying something like
slangc -target hlsl -no-mangle -O0 -minimum-slang-optimization input.slang -o output.hlsl
