Source: rustc
Version: 1.23.0+dfsg1-1
Severity: normal
Tags: patch
User: debian-powerpc at lists.debian.org
Usertags: powerpcspe
Forwarded: https://github.com/rust-lang/rust/pull/48484
Hello!
Please include the attached patch when packaging rustc 1.24 which adds
support for the powerpcspe target allowing rustc to be bootstrapped
for this architectures.
We still need to fix LLVM on powerpcspe, but that should be a matter
of disabling LLDB for powerpcspe in debian/rules.
Thanks,
Adrian
