Firtool and aarch64

[timmerrifield]

Hi,

I don't see any Firtool releasee binaries for aarch64. Is that because it's not supported?

Thanks!
Tim

You're asking about Linux aarch64, macOS, or both?

firtool should work fine building both from source (I build it on macOS and use it locally). Conveniently, the published macOS x64 binaries should also work fine on aarch64 due to Rosetta.

We can add support for publishing the aarch64 binaries as well, nonetheless. Historically, I think GitHub didn't support aarch64 macOS runners when we set this up. They do now and Linux aarch64 was added this month.

Thanks! I was trying to set up Chisel in a Linux VM running on my mac. Chisel was trying to pull down firtool from maven using https://repo1.maven.org/maven2/org/chipsalliance/llvm-firtool/1.62.1/llvm-firtool-1.62.1-linux-aarch64.jar which is not available.

I'll try from source for now.
