2012-02-09GlobalOpt: Be more aggressive about elminating side-effect free static dtors.Benjamin Kramer
GlobalOpt runs early in the pipeline (before inlining) and complex class hierarchies often introduce bitcasts or GEPs which weren't optimized away. Teach it to ignore side-effect free instructions instead of depending on other passes to remove them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150174 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-09Remove static initializer from DataStream.cppDavid Blaikie
If someone would prefer a clear name for the 'success' error_value we could come up with one - potentially just a 'named constructor' style 'error_value::success()' to make this expression more self-documenting. If I see this come up in other cases I'll certainly consider it. One step along the way to resolving PR11944. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150120 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-09Erase dead copies that are clobbered by a call.Jakob Stoklund Olesen

2012-02-09Handle register masks when searching for EFLAGS clobbers.Jakob Stoklund Olesen
Calls clobber the flags, but when using register masks there is no EFLAGS<imp-def> operand. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150117 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-09Never delete instructions that define reserved registers.Jakob Stoklund Olesen
I think this was already the intention, but DeadMachineInstructionElim was accidentally tracking the liveness of reserved registers. Now, instructions with reserved defs are never deleted. This prevents the call stack adjustment instructions from getting deleted when enabling register masks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150116 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-08Handle register masks in MachineCopyPropagation.Jakob Stoklund Olesen
For simplicity, treat calls with register masks as basic block boundaries. This means we can't copy propagate callee-saved registers across calls, but I don't think that is a big deal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150108 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-08Codegen pass definition cleanup. No functionality.Andrew Trick
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

2012-02-08Use TSFlag bit to describe instruction properties.Brendon Cahoon
Creating the isPredicated TSFlag enables the code to use the property defined in the instruction format instead of using a large switch statement. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150078 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-08Keep track of register masks in LiveIntervalAnalysis.Jakob Stoklund Olesen
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
