            Bug ID: 18463
           Summary: [powerpc-darwin] cpusubtype mismatches between
                    integrated/no-integrated-as
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: PowerPC
          Assignee: unassignedbugs at nondot.org
          Reporter: fang at csl.cornell.edu
                CC: iains-llvm at btconnect.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

Object files written by the integrated-as get a different CPU subtype than
using no-integrated-as.  

% otool -h

gcc40-stage2-build/lib/Support/CMakeFiles/LLVMSupport.dir/IsNAN.cpp.o:

      magic cputype cpusubtype   filetype ncmds sizeofcmds      flags

-----------------------------^ here

Is this perhaps related to the .machine directive in AsmParser?

Once we get this to match, I can do a direct object comparison between stage-2
with/without integrated-as.
