* Simplify the logic of getting hold of a PHI predecessor block.Gabor Greif2009-01-231-4/+2
| | | | | | | | | There is now a direct way from value-use-iterator to incoming block in PHINode's API. This way we avoid the iterator->index->iterator trip, and especially the costly getOperandNo() invocation. Additionally there is now an assertion that the iterator really refers to one of the PHI's Uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62869 91177308-0d34-0410-b5e6-96231b3b80d8
* Change create*Pass factory functions to return Pass* instead ofDaniel Dunbar2008-10-221-1/+1
| | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58010 91177308-0d34-0410-b5e6-96231b3b80d8

* Enable first-class aggregates support.Dan Gohman2008-07-231-21/+1
| | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53941 91177308-0d34-0410-b5e6-96231b3b80d8

Also, fold RegisterPassBase into PassInfo, make a bunch of its data members const, and rearrange some code to initialize data members in constructors instead of using setter member functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51022 91177308-0d34-0410-b5e6-96231b3b80d8
