These are the likely culprits. David, it looks likely one of yours.
Could you investigate please? And/or revert

Revision: 87016
Changed files:
include/llvm/CodeGen/AsmPrinter.h
Comments:
Add comment flags so AsmPrinter can output additional information when
emitting comments. These flags carry semantic information not otherwise
easily derivable from the IR text.

Changed at: Thu 12 Nov 2009 12:24:53
Revision: 87018
Changed files:
include/llvm/CodeGen/MachineInstr.h
Comments:
Add AsmPrinter comment flags to machine instructions so that AsmPrinter
can emit extra information in comments.

Revision: 87019
Changed files:
include/llvm/CodeGen/PseudoSourceValue.h
lib/CodeGen/PseudoSourceValue.cpp
Comments:
Make FixedStackPseudoSourceValue a first-class PseudoSourceValue by
making it visible to clients and adding LLVM-style cast capability.
This will be used by AsmPrinter to determine when to emit spill comments
for an instruction.

Revision: 87020
Changed files:
include/llvm/ADT/StringRef.h
lib/CodeGen/SelectionDAG/TargetLowering.cpp
lib/Support/StringRef.cpp
lib/Target/X86/X86ISelLowering.cpp
tools/bugpoint/ToolRunner.cpp
Comments:
Add compare_lower and equals_lower methods to StringRef. Switch all
users of
StringsEqualNoCase (from StringExtras.h) to it.

Comments:
Add a bool flag to StackObjects telling whether they reference spill
slots. The AsmPrinter will use this information to determine whether to
print a spill/reload comment.
Remove default argument values. It's too easy to pass a wrong argument
value when multiple arguments have default values. Make everything
explicit to trap bugs early.
Update all targets to adhere to the new interfaces..

Revision: 87026
Changed files:
include/llvm/Target/TargetInstrInfo.h
lib/Target/X86/X86InstrInfo.cpp
lib/Target/X86/X86InstrInfo.h
Comments:
Add hasLoadFromStackSlot and hasStoreToStackSlot to return whether a
machine instruction loads or stores from/to a stack slot. Unlike
isLoadFromStackSlot and isStoreFromStackSlot, the instruction may be
something other than a pure load/store (e.g. it may be an arithmetic
operation with a memory operand). This helps AsmPrinter determine when
to print a spill/reload comment.
This is only a hint since we may not be able to figure this out in all
cases. As such, it should not be relied upon for correctness.
Implement for X86. Return false by default for other architectures.
