* "In order to ease automatic bindings generation, it would be helpful if ↵Chris Lattner2010-01-095-70/+71
| | | | | | | | | | boolean values were distinguishable from integers. The attached patch introduces "typedef int LLVMBool;", and uses LLVMBool instead of int throughout the C API, wherever a boolean value is called for." Patch by James Y Knight! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93079 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove workaround in PostDominatorsTobias Grosser2010-01-072-19/+6
| | | | | | | | Remove a FIXME and unify code that was necessary to work around broken updateDFSNumbers(). Before updateDFSNumbers() did not work correctly for post dominators. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92968 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix DFS number calculation for postdominatorsTobias Grosser2010-01-071-23/+29
| | | | | | | | | | The DFS number calculation for postdominators was broken. In the case of multiple exits that form the post dominator root nodes, do not iterate over all exits, but start from the virtual root node. Otherwise bbs, that are not post dominated by any exit but by the virtual root node, will never be assigned a DFS number. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92967 91177308-0d34-0410-b5e6-96231b3b80d8

* Add Target hook to duplicate machine instructions.Jakob Stoklund Olesen2010-01-061-0/+8
| | | | | | | Some instructions refer to unique labels, and so cannot be trivially cloned with CloneMachineInstr. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92873 91177308-0d34-0410-b5e6-96231b3b80d8
* Teach dag combine to fold the following transformation more aggressively:Evan Cheng2010-01-062-2/+5
| | | | | | | | | | | (OP (trunc x), (trunc y)) -> (trunc (OP x, y)) Unfortunately this simple change causes dag combine to infinite looping. The problem is the shrink demanded ops optimization tend to canonicalize expressions in the opposite manner. That is badness. This patch disable those optimizations in dag combine but instead it is done as a late pass in sdisel. This also exposes some deficiencies in dag combine and x86 setcc / brcond lowering. Teach them to look pass ISD::TRUNCATE in various places. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92849 91177308-0d34-0410-b5e6-96231b3b80d8
