2012-08-29	Make MemoryBuiltins aware of TargetLibraryInfo.	Benjamin Kramer
	This disables malloc-specific optimization when -fno-builtin (or -ffreestanding) is specified. This has been a problem for a long time but became more severe with the recent memory builtin improvements. Since the memory builtin functions are used everywhere, this required passing TLI in many places. This means that functions that now have an optional TLI argument, like RecursivelyDeleteTriviallyDeadFunctions, won't remove dead mallocs anymore if the TLI argument is missing. I've updated most passes to do the right thing. Fixes PR13694 and probably others. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162841 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-01	Propagate TargetLibraryInfo throughout ConstantFolding.cpp and	Chad Rosier
	InstructionSimplify.cpp. Other fixups as needed. Part of rdar://10500969 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145559 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-03	Speed up instsimplify by about 10-15% by not bothering to retry	Duncan Sands
	InstructionSimplify on instructions that didn't change since the last time round the loop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122745 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-31	Simplify this pass by using a depth-first iterator to ensure that all	Duncan Sands
	operands are visited before the instructions themselves. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122647 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-31	Zap dead instructions harder.	Duncan Sands
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122645 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-21	Visit instructions deterministically. Use a FIFO so as to approximately	Duncan Sands
	visit instructions before their uses, since InstructionSimplify does a better job in that case. All this prompted by Frits van Bommel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122343 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-21	If an instruction simplifies, try again to simplify any uses of it. This is	Duncan Sands
	not very important since the pass is only used for testing, but it does make it more realistic. Suggested by Frits van Bommel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122336 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-20	Oops, forgot to add the pass itself!	Duncan Sands
