            Bug ID: 124547
           Summary: [16 Regression] JIT fails to use linker version script
           Product: gcc
           Version: 16.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rguenth at gcc dot gnu.org
  Target Milestone: ---

Recently (between r16-7922 and r16-8070) the following regressed:

[  525s] checking linker --version-script option... no
[  525s] checking linker soname option... no
[  525s] checking linker --demangle support... no

causing libgccjit to build w/o symbol versions.

We do, in gcc/configure.ac:

AC_MSG_CHECKING(linker --version-script option)
gcc_cv_ld_version_script=no 
ld_version_script_option=''
if test $in_tree_ld = yes || test x"$gnu_ld_flag" = xyes; then
  gcc_cv_ld_version_script=yes
  ld_version_script_option='--version-script'
elif test x$gcc_cv_ld != x; then
  case "$target" in
    # Solaris 2 ld always supports -M.  It also supports a subset of
    # --version-script since Solaris 11.4, but requires
    # -z gnu-version-script-compat to activate.
    *-*-solaris2*)
      gcc_cv_ld_version_script=yes
      ld_version_script_option='-M'
      ;;
  esac
fi

so I suspect one of Rainers change.
