           Summary: asm calls should be marked nounwind
           Product: new-bugs
           Version: unspecified
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: baldrick at free.fr

The inliner knows that asm calls cannot unwind.  If asm calls were
marked nounwind this logic would not be needed, and all the places
that reason about nounwind calls would automatically do the same
for asm.
