Bug ID: 99690 Summary: gcc/config/m68k/t-mlibs doesn't allow extending MULTILIB_EXCEPTIONS Product: gcc Version: 7.5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: miro.kropacek at gmail dot com Target Milestone: --- gcc/config/m68k/t-mlibs nicely unifies various m68k options and mappings. However it doesn't allow extending (or overriding) the MULTILIB_EXCEPTIONS macro the same way the M68K_MLIB_DIRNAMES and M68K_MLIB_OPTIONS does: # Add subtarget specific options & dirs. MULTILIB_DIRNAMES += $(M68K_MLIB_DIRNAMES) MULTILIB_OPTIONS += $(M68K_MLIB_OPTIONS) Is there a reason for that?
