[PowerPC] Support ".machine any" The PowerPC assembler is supposed to provide a directive .machine that allows switching the supported CPU instruction set on the fly. Since we do not yet check CPU feature sets at all and always accept any available instruction, this is not really useful at this point. However, it makes sense to accept (and ignore) ".machine any" to avoid spuriously rejecting existing assembler files that use this. llvm-svn: 185924

[PowerPC] Generate little-endian object files As a first step towards real little-endian code generation, this patch changes the PowerPC MC layer to actually generate little-endian object files. This involves passing the little-endian flag through the various layers, including down to createELFObjectWriter so we actually get basic little-endian ELF objects, emitting instructions in little-endian order, and handling fixups and relocations as appropriate for little-endian. The bulk of the patch is to update most test cases in test/MC/PowerPC to verify both big- and little-endian encodings. (The only test cases *not* updated are those that create actual big-endian ABI code, like the TLS tests.) Note that while the object files are now little-endian, the generated code itself is not yet updated, in particular, it still does not adhere to the ELFv2 ABI. llvm-svn: 204634
