Sanjoy Das	99ca015392	[OperandBundles] Treat "deopt" operand bundles specially ... Teach LLVM optimize to more precisely in the presence of "deopt" operand bundles. "deopt" operand bundles imply that the call they're attached to is at least `readonly` (i.e. they don't imply clobber semantics), and they don't capture their bundle operands. llvm-svn: 254118	2015-11-26 01:16:05 +00:00
Sanjoy Das	b7c31d3a27	[OperandBundles] Teach AliasAnalysis about operand bundles ... Summary: If a `CallSite` has operand bundles, then do not peek into the called function to get a more precise `ModRef` answer. This is tested using `argmemonly`, `-basicaa` and `-gvn`; but the functionality is not specific to any of these.
