[AARCH64] Enable AARCH64 lit tests on windows dev machines As discussed on PR27654, this patch fixes the triples of a lot of aarch64 tests and enables lit tests on windows This will hopefully help stop cases where windows developers break the aarch64 target Differential Revision: https://reviews.llvm.org/D22191 llvm-svn: 275973

ARM64: initial backend import 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

; The target lowering for integer comparisons was replacing some DAG nodes
; during operation legalization, which resulted in dangling pointers,
; cycles in DAGs, and eventually crashes. This is the testcase for
; one of those crashes. (rdar://10653656)

[opaque pointer type] Add textual IR support for explicit type parameter to load instruction Essentially the same as the GEP change in r230786. A similar migration script can be used to update test cases, though a few more test case improvements/changes were required this time around: (r229269-r229278) import fileinput import sys import re pat = re.compile(r"((?:=|:|^)\s*load (?:atomic )?(?:volatile )?(.*?))(| addrspace\(\d+\) *)\*($| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$)") for line in sys.stdin: sys.stdout.write(re.sub(pat, r"\1, \2\3*\4", line)) Reviewers: rafael, dexonsmith, grosser Differential Revision: http://reviews.llvm.org/D7649 llvm-svn: 230794
