2010-07-02	Remove invalid assert	Jakob Stoklund Olesen
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107505 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-02	Properly handle debug values during inline spilling.	Jakob Stoklund Olesen
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107503 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-02	Rematerialize as much as possible before inserting spills and reloads.	Jakob Stoklund Olesen
	This allows us to recognize the common case where all uses could be rematerialized, and no stack slot allocation is necessary. If some values could be fully rematerialized, remove them from the live range before allocating a stack slot for the rest. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107492 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-01	Add memory operand folding support to InlineSpiller.	Jakob Stoklund Olesen
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107355 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-30	Add support for rematerialization to InlineSpiller.	Jakob Stoklund Olesen
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107351 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-30	Remember to track spill slot uses in VirtRegMap when inserting loads and stores.	Jakob Stoklund Olesen
	LocalRewriter::runOnMachineFunction uses this information to mark dead spill slots. This means that InlineSpiller now also works for functions that spill. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107302 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-29	Begin implementation of an inline spiller.	Jakob Stoklund Olesen
	InlineSpiller inserts loads and spills immediately instead of deferring to VirtRegMap. This is possible now because SlotIndexes allows instructions to be inserted and renumbered. This is work in progress, and is mostly a copy of TrivialSpiller so far. It works very well for functions that don't require spilling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107227 91177308-0d34-0410-b5e6-96231b3b80d8
