Auto merge of #127328 - Oneirical:yield-to-petestrians, r=jieyouxu · rust-lang/rust@d4a6200 (original) (raw)
``

`+
// Setting the linker flavor as a C compiler should cause the output of the -l flags to be
`
``
2
`+
// prefixed by -Wl, except when a flag is requested to be verbatim. A bare linker (ld) should
`
``
3
`+
// never cause prefixes to appear in the output. This test checks this ruleset twice, once with
`
``
4
`+
// explicit flags and then with those flags passed inside the rust source code.
`
``
5
`+
// See https://github.com/rust-lang/rust/pull/118202
`
``

+
``
7
`+
//@ only-linux
`
``
8
`` +
// Reason: the gnu-cc linker is only available on linux
