Dan Gohman 3b205175ea Fix SpeculativelyExecuteBB to either speculate all or none of the phis
present in the bottom of the CFG triangle, as the transformation isn't
ever valuable if the branch can't be eliminated.

Also, unify some heuristics between SimplifyCFG's multiple
if-converters, for consistency.

This fixes rdar://10627242.

AddrModeMatcher.cpp Add a little heuristic to Value::isUsedInBasicBlock to speed it up for small basic blocks. 2011-12-05 17:23:27 +00:00
BasicBlockUtils.cpp SplitBlockPredecessors uses ArrayRef instead of Data and Size. 2011-12-09 21:19:53 +00:00
BasicInliner.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

BuildLibCalls.cpp Add support for custom names for library functions in TargetLibraryInfo. Add a custom name for fwrite and fputs on x86-32 OSX. Make SimplifyLibCalls honor the custom 2011-11-17 01:27:36 +00:00

LoopSimplify.cpp Make loop preheader insertion in LoopSimplify handle the case where the loop header is a landing pad correctly (by splitting the landingpad out of the loop header). Make some adjustments to the rest of LoopSimplify to make it clear that the rest of LoopSimplify isn't making bad assumptions about the presence of landing pads. PR11575. 2011-12-15 00:50:34 +00:00
