I'm using crosstool-ng for building a toolchain because GCC 9 from musl-toolchain.sh
has float ABI issues (?) and can't compile LLVM, and writing a crosstool-ng config for a target feels less hacky than yet another target specific shell script. I also defined a kernel version, since there wasn't one specified before. If a lower version is desired, just let me know. I also tried to match the rust configure args with the loongarch64 musl tier 2 target.
The resulting compiler works fine, built with DEPLOY=1 ./src/ci/docker/run.sh dist-powerpc64le-linux
and tested on Alpine Linux in a VM and on a bare metal POWER8 machine:

Thanks. The bootstrap bits look fine to me (r=me for bootstrap bits and a second on the compiler changes), I'll hand this off to T-infra to look at the CI changes.
This comment was marked as off-topic.
The build looks like it got stuck at some point
Build failure is unrelated.

Compatibility Notes
[
rustc
no longer treats thetest
cfg as a well known check-cfg] (rust-lang/rust#131729), instead it is up to the build systems and users of--check-cfg
[^check-cfg] to set it as a well known cfg using--check-cfg=cfg(test)
.This is done to enable build systems like Cargo to set it conditionally, as not all source files are suitable for unit tests.
[Cargo (for now) unconditionally sets the
test
cfg as a well known cfg] (rust-lang/cargo#14963). [^check-cfg]: https://doc.rust-lang.org/nightly/rustc/check-cfg.html[Disable potentially incorrect type inference if there are trivial and non-trivial where-clauses] (rust-lang/rust#132325)
std::env::home_dir()
has been deprecated for years, because it can give surprising results in some Windows configurations if theHOME
environment variable is set (which is not the normal configuration on Windows). We had previously avoided changing its behavior, out of concern for compatibility with code depending on this non-standard configuration. Given how long this function has been deprecated, we're now fixing its behavior as a bugfix. A subsequent release will remove the deprecation for this function.[Make

Proposed changes to behavior should be submitted there as MRs.
Release Notes
rust-lang/rust (rust)
v1.85.0
==========================
Language
- The 2024 Edition is now stable. See the edition guide for more details.
- Stabilize async closures See RFC 3668 for more details.
- Stabilize
#[diagnostic::do_not_recommend]
- Add
unpredictable_function_pointer_comparisons
lint to warn against function pointer comparisons - Lint on combining
#[no_mangle]
and#[export_name]
attributes.
Compiler
- The unstable flag
-Zpolymorphize
has been removed, see rust-lang/compiler-team#810 for some background.
Platform Support
Refer to Rust's [platform support page][platform-support-doc] for more information on Rust's tiered platform support.
Libraries
Panics in the standard library now have a leading
library/
in their pathstd::env::home_dir()
on Windows now ignores the non-standard$HOME
environment variableIt will be un-deprecated in a subsequent release.
Stabilized APIs
BuildHasherDefault::new
ptr::fn_addr_eq
io::ErrorKind::QuotaExceeded
io::ErrorKind::CrossesDevices
{float}::midpoint

Cargo
- Add future-incompatibility warning against keywords in cfgs and add raw-idents
- Stabilize higher precedence trailing flags
- Pass

Compatibility Notes
rustc
no longer treats thetest
cfg as a well known check-cfg, instead it is up to the build systems and users of--check-cfg
[^check-cfg] to set it as a well known cfg using--check-cfg=cfg(test)
.This is done to enable build systems like Cargo to set it conditionally, as not all source files are suitable for unit tests. Cargo (for now) unconditionally sets the
test
cfg as a well known cfg. [^check-cfg]: https://doc.rust-lang.org/nightly/rustc/check-cfg.htmlDisable potentially incorrect type inference if there are trivial and non-trivial where-clauses
std::env::home_dir()
has been deprecated for years, because it can give surprising results in some Windows configurations if theHOME
environment variable is set (which is not the normal configuration on Windows). We had previously avoided changing its behavior, out of concern for compatibility with code depending on this non-standard configuration. Given how long this function has been deprecated, we're now fixing its behavior as a bugfix. A subsequent release will remove the deprecation for this function.Make
core::ffi::c_char
signedness more closely match that of the platform-defaultchar
This changed
c_char
from ani8
tou8
or vice versa on many Tier 2 and 3 targets (mostly Arm and RISC-V embedded targets). The new definition may result in compilation failures but fixes compatibility issues with C.The
libc
crate matches this change as of its 0.2.169 release.Increase
