We still think we'll be able to compile libcore before the end of the
summer, we've made great progress and few items are left. But keep in
mind we're targeting an older version of rust (1.49) and libcore is
smaller than the standard library. We still have a lot of testing to do
and we expect many bugs.
The next targeted version will probably be rust 1.78 as we want to keep
up with rust for linux. This shouldn't be too long as most of the
features are coming from either standard library modifications or
nightly features we already had to support for 1.49.
We expect to be able to compile some 1.49 code correctly next year at
best. I would like to bring to your attention rustc_codegen_gcc which
adds a gcc backend to the rustc frontend, although not a full gcc
compiler it could help supporting some architectures that are currently
not supported by llvm.
