* Fix a memory leak in the hexagon scheduler. We call initialize here moreChandler Carruth2013-07-27
| | | | | | | | | | | | | than once, and the second time through we leaked memory. Found thanks to the vg-leak bot, but I can't locally reproduce it with valgrind. The debugger confirms that it is in fact leaking here. This whole code is totally gross. Why is initialize being called on each runOnFunction??? Why aren't these OwningPtr<>s, and why aren't their lifetimes better defined? Anyways, this is just a surgical change to help out the leak checking bots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187299 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix broken asserts that never fire.Richard Trieu2013-06-28
| | | | | | | | | Change assert("text") to assert(0 && "text"). The first case is a const char * to bool conversion, which always evaluates to true, never triggering the assert. The second case will always trigger the assert. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185227 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | Replace the ill-defined MinLatency and ILPWindow properties with with straightforward buffer sizes: MCSchedMode::MicroOpBufferSize MCProcResourceDesc::BufferSize These can be used to more precisely model instruction execution if desired. Disabled some misched tests temporarily. They'll be reenabled in a few commits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184032 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove the MachineMove class.Rafael Espindola2013-05-13
| | | | | | | | | | | | It was just a less powerful and more confusing version of MCCFIInstruction. A side effect is that, since MCCFIInstruction uses dwarf register numbers, calls to getDwarfRegNum are pushed out, which should allow further simplifications. I left the MachineModuleInfo::addFrameMove interface unchanged since this patch was already fairly big. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181680 91177308-0d34-0410-b5e6-96231b3b80d8
