            Bug ID: 110085
           Summary: make clean inside the gcc directory when configured
                    with m2 language and for sh-elf messes up
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

make clean does:
# Delete files used by the "multilib" facility (including libgcc subdirs).
        -rm -f multilib.h tmpmultilib*
        -if [ "x$(MULTILIB_DIRNAMES)" !=3D x ] ; then \
          rm -rf $(MULTILIB_DIRNAMES); \
        else if [ "x$(MULTILIB_OPTIONS)" !=3D x ] ; then \
          rm -rf `echo $(MULTILIB_OPTIONS) | sed -e 's/\// /g'`; \
        fi ; fi


and one of the MULTILIB_DIRNAMES for sh-elf is m2 but m2 is also the name of
the language.

I think that part of the gcc/Makefile.in can be removed now (since libgcc is
not built inside the gcc directory for years now) but I am not 100% sure.=
