             Bug #: 52144
           Summary: ARM should support arm/thumb function attribute to
                    permit different instruction sets in the same source
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: rafael.carre@gmail.com


Reference: First message of http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40419

Mixing thumb and ARM in the same source is currently not possible.

That would permit LTO to work when mixing those and close
