            Bug ID: 67604
           Summary: shrink-wrap doesn't allow multiple entries
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ada
          Assignee: segher at gcc dot gnu.org
          Reporter: segher at gcc dot gnu.org
  Target Milestone: ---

The current shrink-wrap implementation does not allow putting the
prologue before blocks with multiple entry points.  This is suboptimal;
handling this case makes it possible to shrink-wrap 10% or more more
functions.
