           Summary: Should propagate nothrow attribute to LLVM IR
           Product: tools
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: llvm-g++
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: asl at math.spbu.ru


When exceptions are enabled any call should be thought as "could throw".
However, FE knows, that some call couldn't throw. This information should be
propagated to LLVM IR. This moderately reduces size of generated code.
