[llvm-dev] [cfe-dev] ?==?utf-8?q? [Release-testers] [9.0.0?==?utf-8?q? Release] Release Candidate 6 is here

[Sam Elliott via llvm-dev]

Hi Bernhard,

Thank you for trying the RISC-V backend, and looking for comments in the backend before filing issues.

The RISC-V backend has only recently become stable, and there are indeed some bugs in the trickier parts of the backend.

We (lowRISC and other RISC-V backend contributors) would welcome you to file bugs against the backend, but we do not feel these bugs should block the release, as they are not regressions.

Sam

Unless someone asks me to, I won't send bug reports for what's still failing there because the code already has lots of comments saying it's broken (e.g. abi is always assumed to be ilp32 even when the target system is lp64d).
