Get rid of the global CFGOnly flag by threading a ShortNames parameters through the GraphViz rendering code.
Update other uses in the codebase for this change.

This is suboptimal in several aspects, see the commented out assertion.
I need to talk to Daniel about this.

llvm-svn: 74057

Fixed a bug in LiveInterval scaling (failure to scale VNI defs correctly), removed old TODO comments.

llvm-svn: 74054

Fix support for inline asm input / output operand tying when operand spans across multiple registers (e.g. two i64 operands in 32-bit mode).

trip counts in more cases.

Generalize ScalarEvolution's isLoopGuardedByCond code to recognize
And and Or conditions, splitting the code out into an
isNecessaryCond helper function so that it can evaluate Ands and Ors
recursively, and make SCEVExpander be much more aggressive about
hoisting instructions out of loops.

test/CodeGen/X86/pr3495.ll has an additional instruction now, but
it appears to be due to an arbitrary register allocation difference.

Change getIntegerSCEV's comment to avoid mentioning FP types,
and re-implement it in terms of getConstant instead of getUnknown.

list in their destructors.  Yes, I know it's horrible.

C bindings.  Change all the backend "Initialize" functions to have C linkage.
Change the "llvm/Config/Targets.def" header to use C-style comments to avoid
compile warnings.

It is not a good idea to have data member's name match argument's name. In fact, it is a simple receipe to waste an hour or so.

Use atomic operations when accessing statistics, and make the lazy initialization of statistics actually threadsafe.

llvm-svn: 74005

llvm-svn: 74004

Make timers threadsafe again.  This isn't quite as nice as I'd hoped (it uses locking rather than atomic arithmetic),
but should work on all the platforms we care about.

I might revisit this if a totally awesome way to do it occurs to me.

instructions, which implies that there is an explicit memory operand.  There is
(however) no explicit memory operand; although this is a store, the only memory
operand is implicit, indicated by DS:EDI.  This causes the table-generation code
for the disassembler to report an error."
