Igor Laevsky	0fa4819dd8	[LazyValueInfo] Report nonnull range for nonnull pointers ... Currently LazyValueInfo will report only alloca's as having nonnull range. For loads with !nonnull metadata it will bailout with no additional information. Same is true for calls returning nonnull pointers. This change extends LazyValueInfo to handle additional nonnull instructions. Differential Revision: http://reviews.llvm.org/D12932 llvm-svn: 247985	2015-09-18 13:01:48 +00:00
Igor Laevsky	bdc1eafe20	[CorrelatedValuePropagation] Infer nonnull attributes ... LazuValueInfo can prove that value is nonnull based on the context information. Make use of this ability to infer nonnull attributes for the call arguments. Differential Revision: http://reviews.llvm.org/D12836 llvm-svn: 247707	2015-09-15 17:51:50 +00:00
David Blaikie	a79ac14fa6	[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	2015-02-27 21:17:42 +00:00
