* AArch64/ARM64: move ARM64 into AArch64's placeTim Northover2014-05-241-888/+0
| | | | | | | | | | | | | | | This commit starts with a "git mv ARM64 AArch64" and continues out from there, renaming the C++ classes, intrinsics, and other target-local objects for consistency. "ARM64" test directories are also moved, and tests that began their life in ARM64 use an arm64 triple, those from AArch64 use an aarch64 triple. Both should be equivalent though. This finishes the AArch64 merge, and everyone should feel free to continue committing as normal now. llvm-svn: 209577
* ARM64: model pre/post-indexed operations properly.Tim Northover2014-05-221-11/+21
| | | | | | | | | | We should be keeping track of the writeback on these instructions, otherwise we're relying on LLVM's stupidity for correct code. Fortunately, the MC layer can now handle all required constraints, which means we can get rid of the CodeGen only PseudoInsts too. llvm-svn: 209426

This adds a second implementation of the AArch64 architecture to LLVM, accessible in parallel via the "arm64" triple. The plan over the coming weeks & months is to merge the two into a single backend, during which time thorough code review should naturally occur. Everything will be easier with the target in-tree though, hence this commit. llvm-svn: 205090
