2012-06-20	Fix two rather subtle internal vs. external linker issues.	Chandler Carruth	1	-25/+20
	I'll admit I'm not entirely satisfied with this change, but it seemed the cleanest option. Other suggestions quite welcome The issue is that the traits specializations have static methods which return the typedef'ed PHI_iterator type. In both the IR and MI layers this is typedef'ed to a custom iterator class defined in an anonymous namespace giving the types and the functions returning them internal linkage. However, because the traits specialization is defined in the 'llvm' namespace (where it has to be, specialized template lives there), and is in turn used in the templated implementation of the SSAUpdater. This led to the linkage conflict that Clang now warns about. The simplest solution to me was just to define the PHI_iterator as a nested class inside the trait specialization. That way it still doesn't get scoped widely, it can't be accidentally reused somewhere, etc. This is a little gross just because nested class definitions are a little gross, but the alternatives seem more ad-hoc. llvm-svn: 158799

2011-12-06	Mix some minor misuse of MachineBasicBlock iterator.	Evan Cheng	1	-3/+3

2010-05-10	Fix PR7096. When a block containing multiple defs is tail duplicated, the	Bob Wilson	1	-1/+1
	SSAUpdater for the value from the first def may see uses of undefined values, because the later defs will not have been updated yet. llvm-svn: 103407
2010-05-04	Combine the implementations of the core part of the SSAUpdater and	Bob Wilson	1	-437/+109
	MachineSSAUpdater to avoid duplicating all the code. llvm-svn: 103060
2010-04-26	Update MachineSSAUpdater with the same changes I made for the IR-level	Bob Wilson	1	-122/+428
	SSAUpdater. I'm going to try to refactor this to share most of the code between them. llvm-svn: 102353
2010-04-02	stop using DebugLoc::getUnknownLoc()	Chris Lattner	1	-1/+1

2010-02-10	fix missing #includes.	Chris Lattner	1	-0/+1
	llvm-svn: 95745
2010-02-09	move target-independent opcodes out of TargetInstrInfo	Chris Lattner	1	-8/+8
	into TargetOpcodes.h. #include the new TargetOpcodes.h into MachineInstr. Add new inline accessors (like isPHI()) to MachineInstr, and start using them throughout the codebase. llvm-svn: 95687

2009-12-04	- If the reaching definition is an undef and the use is a PHI, add the ↵	Evan Cheng	1	-11/+15
