2011-02-26 | Add some DAGCombines for (adde 0, 0, glue), which are useful to optimize ↵ | Benjamin Kramer | 1 | -0/+26 | |
legalized code for large integer arithmetic. 1. Inform users of ADDEs with two 0 operands that it never sets carry 2. Fold other ADDs or ADDCs into the ADDE if possible It would be neat if we could do the same thing for SETCC+ADD eventually, but we can't do that in target independent code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126557 91177308-0d34-0410-b5e6-96231b3b80d8 |
