Start using GPR's to copy around mmx value instead of mmx regs. GCC apparently does this, and code depends on not having to do emms when this happens. This is x86-64 only so far, second half should handle x86-32. rdar://5741668 llvm-svn: 47470

; This test should use GPRs to copy the mmx value, not MMX regs. Using mmx regs,

copy mmx values from/to memory with GPRs on x86-32 instead of with mmx registers. This horribleness is apparently done by gcc to avoid having to insert emms in places that really should have it. This is the second half of rdar://5741668. llvm-svn: 47474

entry:
[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
