Bug#1140596: llvm: LTO likely broken on riscv64

[Chris Hofstaedtler]

Package: clang-21,clang-22
Severity: important
X-Debbugs-CC: debian-riscv at lists.debian.org

Hi,

as observed in some package build logs and as noted in this upstream 
comment, it appears LTO is either broken or at least emits code not 
matching the ABI.

https://github.com/llvm/llvm-project/issues/50591

In some Debian package build logs one can find this output:

   Hard-float 'd' ABI can't be used for a target that doesn't support the D instruction set extension (ignoring target-abi)

Now this might be harmless or it might fail.

Please clarify the current status, especially within Debian.

Thanks,
Chris
