* Fix SplitCriticalEdge to properly update LCSSA form when splitting aDan Gohman2009-09-091-16/+1
| | | | | | | | | | loop exit edge -- new PHIs may be needed not only for the additional splits that are made to preserve LoopSimplify form, but also for the original split. Factor out the code that inserts new PHIs so that it can be used for both. Remove LoopRotation.cpp's code for manually updating LCSSA form, as it is now redundant. This fixes PR4934. llvm-svn: 81363

| | | | | | | | | | | LoopPass*. - Although less precise, this means they can be used in clients without RTTI (who would otherwise need to include LoopPass.h, which eventually includes things using dynamic_cast). This was the simplest solution that presented itself, but I am happy to use a better one if available. llvm-svn: 58010

* Enable first-class aggregates support.Dan Gohman2008-07-231-29/+5
| | | | | | | | | | | | Remove the GetResultInst instruction. It is still accepted in LLVM assembly and bitcode, where it is now auto-upgraded to ExtractValueInst. Also, remove support for return instructions with multiple values. These are auto-upgraded to use InsertValueInst instructions. The IRBuilder still accepts multiple-value returns, and auto-upgrades them to InsertValueInst instructions. llvm-svn: 53941
