Add a new string member to the TargetOptions struct for the name of the abi we should be using. For targets that don't use the option there's no change, otherwise this allows external users to set the ABI via string and avoid some of the -backend-option pain in clang. Use this option to move the ABI for the ARM port from the Subtarget to the TargetMachine and update the testcases accordingly since it's no longer valid to set via -mattr. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@224492 91177308-0d34-0410-b5e6-96231b3b80d8

Teach AsmPrinter how to print odd constants. Fix an assertion when the compiler encounters big constants whose bit width is not a multiple of 64-bits. Although clang would never generate something like this, the backend should be able to handle any legal IR. <rdar://problem/13363576> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183544 91177308-0d34-0410-b5e6-96231b3b80d8

[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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@230794 91177308-0d34-0410-b5e6-96231b3b80d8
