            Bug ID: 110624
           Summary: Xcode 15 ld warns about -macosx_version_min
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
                CC: iains at gcc dot gnu.org
  Target Milestone: ---
              Host: x86_64-apple-darwin23.0.0
            Target: x86_64-apple-darwin23.0.0
             Build: x86_64-apple-darwin23.0.0

When bootstrapping current trunk on macOS 14.0 beta 3 with Xcode 15 beta 3,
every single link test in the testsuite fails with excess errors since ld n=
ow
warns

-macosx_version_min has been renamed to -macos_version_min

I'm currently working on patches to prune that message in the testsuite, pl=
us
large additional patches to the gm2 testsuite to perform the pruning at all.

Ultimately, this should be handled in the driver, though: the warning is new
in Xcode 15 beta 3 (beta 2 didn't have it).  However, ld accepts the new fo=
rm
back to at least Xcode 13 (haven't looked further yet), and it's the only o=
ne
documented in ld(1).=
