[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 interprocedural-basic-aa and associated code. The AliasAnalysis interface needs implementations to be consistent, so any code which wants to support different semantics must use a different interface. It's not currently worthwhile to add a new interface for this new concept. Document that AliasAnalysis doesn't support cross-function queries. llvm-svn: 107776

Remove interprocedural-basic-aa and associated code. The AliasAnalysis interface needs implementations to be consistent, so any code which wants to support different semantics must use a different interface. It's not currently worthwhile to add a new interface for this new concept. Document that AliasAnalysis doesn't support cross-function queries. llvm-svn: 107776

[ModRefInfo] Add must alias info to ModRefInfo. Summary: Add an additional bit to ModRefInfo, ModRefInfo::Must, to be cleared for known must aliases. Shift existing Mod/Ref/ModRef values to include an additional most significant bit. Update wrappers that modify ModRefInfo values to reflect the change. Notes: * ModRefInfo::Must is almost entirely cleared in the AAResults methods, the remaining changes are trying to preserve it. * Only some small changes to make custom AA passes set ModRefInfo::Must (BasicAA). * GlobalsModRef already declares a bit, who's meaning overlaps with the most significant bit in ModRefInfo (MayReadAnyGlobal). No changes to shift the value of MayReadAnyGlobal (see AlignedMap). FunctionInfo.getModRef() ajusts most significant bit so correctness is preserved, but the Must info is lost. * There are cases where the ModRefInfo::Must is not set, e.g. 2 calls that only read will return ModRefInfo::NoModRef, though they may read from exactly the same location.
