Change compiler version for Metal.

[immortalsalomon]

Hello everyone, I hope you are well.

I created this discussion because when I try to run my compiled pipeline using Metal as target, the following error is generated.

Searching online I found this issue: risc0/risc0#999

My question is whether there is a way to define which compiler of Metal to use(version of Metal). And if the answer is yes, how can that be achieved.

Thank you for your support.

Can you possibly provide a reproducer? We haven't been able to repro this locally.

I don't believe the changing the Metal language version will allow more or fewer temporary registers, so likely you need to specify a different schedule. The linked issue seems to indicate there was an error that was fixed by a specific macOS version, not Metal compiler version.
