ARM: stop emitting blx instructions for most calls on MachO. I'm really not sure why we were in the first place, it's the linker's job to convert between BL/BLX as necessary. Even worse, using BLX left Thumb calls that could be locally resolved completely unencodable since all offsets to BLX are multiples of 4. rdar://26182344 llvm-svn: 269101

Fix Thumb2 function call isel. Thumb1 and Thumb2 should share the same instructions for calls since BL and BLX are always 32-bit long and BX is always 16-bit long. Also, we should be using BLX to call external function stubs. llvm-svn: 77756

[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

Remove tail call to preserve this test. A tail call version will follow. llvm-svn: 105422
