@castano Radeon GPU Analzer is the only public tool I know of that can show you register pressure for each instruction: https://radeon-gpu-analyzer-rga.readthedocs.io/en/latest/help_manual.html#id19

@mjp Thanks! That’s exactly what I was looking for.

@castano @mjp Just keep in mind it's "best effort" as there are some assumptions it has to make in presence of image functions. The underlying tool is btw. utils/Shae.exe, you can run it directly on any AMD ISA if you want to.

@mjp @castano it is not terribly hard to write one (from disassembly) FWIW, but yeah, for amd that's great.

@c0de517e @mjp Yes, not hard, assuming you have access to the assembly code, but on mobile that is usually not the case.
