Mark PPC MFTB and DST (and friends) as deprecated Use the new instruction deprecation feature to mark mftb (now replaced with mfspr) and dst (along with the other Altivec cache control instructions) as deprecated when targeting cores supporting at least ISA v2.03. llvm-svn: 190605

[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

mftb 3
Properly handle the mftb instruction. The mftb instruction was incorrectly marked as deprecated in the PPC Backend. Instead, it should not be treated as deprecated, but rather be implemented using the mfspr instruction. A similar patch was put into GCC last year. Details can be found at: https://sourceware.org/ml/binutils/2014-11/msg00383.html. This change will replace instances of the mftb instruction with the mfspr instruction for all CPUs except 601 and pwr3. This will also be the default behaviour. Additional details can be found in: https://llvm.org/bugs/show_bug.cgi?id=23680 Phabricator review: http://reviews.llvm.org/D10419 llvm-svn: 239827
