           Summary: MCAsmStreamer::EmitSymbolAttribute does not use
                    MCAsmInfo settings
           Product: new-bugs
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: code-cleanup, miscompilation
          Severity: minor
          Priority: P2
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org

MCAsmStreamer::EmitSymbolAttribute in lib/MC/MCAsmStreamer.cpp prints
directives for symbols. The directives e.g. '.globl' for a global variable are
hardcoded. If a backend specifies a different GlobalDirective, e.g.
'\t.global\t' in an MCAsmInfo subclass, this directive is not used (triggered
in a custom backend).

AsmPrinter.cpp calls EmitSymbolAttribute in e.g. AsmPrinter::EmitGlobalVariable

Please update EmitSymbolAttribute function to use the MCAsmInfo directives.
