python3-rpm is added (temporarily) to work around https://bugzilla.redhat.com/show_bug.cgi?id=2275274. The binutils-gold dependency is needed for one test. Previously binutils implicitly dependend on binutils-gold. Backport https://github.com/rust-lang/rust/pull/126263 to fix one codegen test failure on s390x. There are some additional test failures on ppc64le and s390x for which I have filed https://github.com/rust-lang/rust/issues/126260 and https://github.com/rust-lang/rust/issues/126261.

Subject: [PATCH] Make issue-122805.rs big endian compatible
|
|
|
|
Instead of not generating the function at all on big endian (which
|
|
makes the CHECK lines fail), instead use to_le() on big endian,
|
|
so that we essentially perform a bswap for both endiannesses.
