[mips] Add the following MIPS options that control gp-relative addressing of small data items: -mgpopt, -mlocal-sdata, -mextern-sdata. Implement gp-relative addressing for constants. Differential Revision: http://reviews.llvm.org/D4903 llvm-svn: 221450

Add register Mips::GP to the list of reserved registers if target is bare-metal to prevent it from being clobbered. mips uses $gp to access small data section. This bug was originally reported by Carl Norum. llvm-svn: 162340

[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
