* Codegen pass definition cleanup. No functionality.Andrew Trick2012-02-083-79/+70
| | | | | | | | | | | | | Moving toward a uniform style of pass definition to allow easier target configuration. Globally declare Pass ID. Globally declare pass initializer. Use INITIALIZE_PASS consistently. Add a call to the initializer from CodeGen.cpp. Remove redundant "createPass" functions and "getPassName" methods. While cleaning up declarations, cleaned up comments (sorry for large diff). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150100 91177308-0d34-0410-b5e6-96231b3b80d8

* Keep track of register masks in LiveIntervalAnalysis.Jakob Stoklund Olesen2012-02-081-0/+43
| | | | | | | | | | | | | Build an ordered vector of register mask operands (i.e., calls) when computing live intervals. Provide a checkRegMaskInterference() function that computes a bit mask of usable registers for a live range. This is a quick way of determining of a live range crosses any calls, and restricting it to the callee saved registers if it does. Previously, we had to discover call clobbers for each candidate register independently. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150077 91177308-0d34-0410-b5e6-96231b3b80d8
