Nick Lewycky a641c07828 Use the target-aware constant folder on expressions to improve the chance ... they'll be simple enough to simulate, and to reduce the chance we'll encounter equal but different simple pointer constants. This removes the symptoms from PR11352 but is not a full fix. A proper fix would either require a guarantee that two constant objects we simulate are folded when equal, or a different way of handling equal pointers (ie., trying a constantexpr icmp on them to see whether we know they're equal or non-equal or unsure). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151093 91177308-0d34-0410-b5e6-96231b3b80d8		2012-02-21 22:08:06 +00:00

ArgumentPromotion.cpp	Update inter-procedural optimizations for atomic load/store.	2011-08-15 22:16:46 +00:00

ConstantMerge.cpp	Re-fix the issue Bill fixed in r147899 in a slightly different way, which doesn't abuse the semantics of linker_private. We don't really want to merge any string constant with a weak_odr global.	2012-01-11 22:06:46 +00:00

InlineAlways.cpp	Inlining and unrolling heuristics should be aware of free truncs.	2011-10-01 01:39:05 +00:00
Inliner.cpp	Refactor code from inlining and globalopt that checks whether a function definition is unused, and enhance it so it can tell that functions which are only used by a blockaddress are in fact dead. This probably doesn't happen much on most code, but the Linux kernel's _THIS_IP_ can trigger this issue with blockaddress. (GlobalDCE can also handle the given tescase, but we only run that at -O3.) Found while looking at PR11180.	2011-10-20 05:23:42 +00:00
