            Bug ID: 113218
           Summary: gcc -pg fails on contemporary FreeBSD
           Product: gcc
           Version: 12.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: driver
          Assignee: unassigned at gcc dot gnu.org
          Reporter: emaste at freebsd dot org
  Target Milestone: ---

FreeBSD retired _p profiled libraries in FreeBSD 14.0, so GCC specs need to be
updated.

Demonstrated below using the default FreeBSD devel/gcc port, but looking at gcc
git I don't see any change.

FreeBSD version:

root@14:~ # uname -a
FreeBSD 14 14.0-RELEASE FreeBSD 14.0-RELEASE #0
releng/14.0-n265380-f9716eee8ab4: Fri Nov 10 05:57:23 UTC 2023    
root@releng1.nyi.freebsd.org:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64

GCC:

root@14:~ # gcc --version

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Basically FBSD_LIB_SPEC in gcc/config/freebsd-spec.h should be modified to
`%{pg:` related parts. But only do that for FBSD_MAJOR >= 14 ...
