Thanks for this! As a reminder the main concern for these new targets is if we decide to build them on CI it takes time and we may not have the CI budget for it. For libstd though it's pretty cheap to build and looking at the timing information we've still got a bit of headroom on (everything is fine with this PR, just wanted to jot this down!) |
@alexcrichton Thanks for the information! I hope that there is only one RISC-V target to add in the future: |

Pkgsrc changes: * Adapt to the move of the implementation of random numbers. * Remove patch which is no longer relevant (Signals.inc) * Cross-build currently fails due to the still unresolved rust-lang/rust#62558, so bootstrap kits for 1.38.0 have to be built natively, and will follow shortly. * Bump bootstrap requirements to 1.37.0 except for armv7-unknown-netbsd-eabihf which I've neither managed to cross-build nor build natively.
