New Revision: 77724
URL: http://llvm.org/viewvc/llvm-project?rev=77724&view=rev
Log:
remove the PPCLinuxTargetAsmInfo implementation of PreferredEHDataFormat,
because it just calls the default impl.
Remove the PPCDarwinTargetAsmInfo version of PreferredEHDataFormat because
it just returns DW_EH_PE_absptr unless on 10.6. However, 10.6 doesn't support
PPC, so the default impl is just fine.
