// Setting the linker flavor as a C compiler should cause the output of the -l flags to be
|
|
|
|
|
// prefixed by -Wl, except when a flag is requested to be verbatim. A bare linker (ld) should
|
|
|
|
|
// never cause prefixes to appear in the output. This test checks this ruleset twice, once with
|
|
|
|
|
// explicit flags and then with those flags passed inside the rust source code.
