* There's no need to consider PHI nodes in the same block as the instructionNick Lewycky2009-07-092-0/+74
| | | | | | | we're inserting sigma/phi functions for. Patch by Andre Tavares. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75138 91177308-0d34-0410-b5e6-96231b3b80d8
* Targets sometimes assign fixed stack object to spill certain callee-savedEvan Cheng2009-07-093-2/+4
| | | | | | | | | | | registers based on dynamic conditions. For example, X86 EBP/RBP, when used as frame register has to be spilled in the first fixed object. It should inform PEI this so it doesn't get allocated another stack object. Also, it should not be spilled as other callee-saved registers but rather its spilling and restoring are being handled by emitPrologue and emitEpilogue. Avoid spilling it twice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75116 91177308-0d34-0410-b5e6-96231b3b80d8
* Improved tracking of value number kills. VN kills are now representedLang Hames2009-07-091-1/+1
| | | | | | | | | | | | | | as an (index,bool) pair. The bool flag records whether the kill is a PHI kill or not. This code will be used to enable splitting of live intervals containing PHI-kills. A slight change to live interval weights introduced an extra spill into lsr-code-insertion (outside the critical sections). The test condition has been updated to reflect this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75097 91177308-0d34-0410-b5e6-96231b3b80d8
