Use %rip-relative addressing on x86-64 whenever practical, as it has a smaller encoding than absolute addressing. llvm-svn: 67002

Fix an x86 code size regression: prefer RIP-relative addressing over absolute addressing even in non-PIC mode (unless the address has an index or something else incompatible), because it has a smaller encoding. llvm-svn: 79553

[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

this test was incorrect for x86-64 static. It passed on darwin, because darwin doesn't have static x86-64 mode. llvm-svn: 75392
