EmitRawText is being called by
void PPCDarwinAsmPrinter::
EmitFunctionStubs(const MachineModuleInfoMachO::SymbolListTy &Stubs)
in lib/Target/PowerPC/PPCAsmPrinter.cpp:
// FIXME: MCize this.
STACKTRACE_INDENT_PRINT("FIXME: MCize this." << std::endl);
OutStreamer.EmitRawText("\tbcl 20, 31, " + Twine(AnonSymbol->getName()));
Can that be fixed? This is blocking me from testing PPCMachObjectWriter.
I'm currently at r175024.</pre>
