Chris Lattner d20699bc87 Momentous day: remove the "O" member from AsmPrinter. Now all
"asm printering" happens through MCStreamer.  This also 
Streamerizes PIC16 debug info, which escaped my attention.

This removes a leak from LLVMTargetMachine of the 'legacy'
output stream.

Chris Lattner 76c564b1bb change a ton of code to not implicitly use the "O" raw_ostream
member of AsmPrinter.  Instead, pass it in explicitly.

Chris Lattner 593916d732 rename NewDebugLoc -> DebugLoc, prune #includes in DebugLoc.h.
This keeps around temporary typedef for clang/llvm-gcc so the
build won't break when I commit this :)

Chris Lattner 915c5f9862 Switch the code generator (except the JIT) onto the new DebugLoc
representation.  This eliminates the 'DILocation' MDNodes for 
file/line/col tuples from -O0 -g codegen.

This remove the old DebugLoc class, making it a typedef for DebugLoc,
I'll rename NewDebugLoc next.

I didn't update the JIT to use the new apis, so it will continue to
work, but be as slow as before.  Someone should eventually do this
or, better yet, rip out the JIT debug info stuff and build the JIT
on top of MC.

Chris Lattner e468f88b26 rearrange MCContext ownership. Before LLVMTargetMachine created it
and passing off ownership to AsmPrinter.  Now MachineModuleInfo
creates it and owns it by value.  This allows us to use MCSymbols
more consistently throughout the rest of the code generator, and
simplifies a bit of code.  This also allows MachineFunction to 
keep an MCContext reference handy, and cleans up the TargetRegistry
interfaces for AsmPrinters.

Jim Grosbach fae913adf8 Change the Value argument to eliminateFrameIndex to a type-tagged value. This
is preparatory to having PEI's scavenged frame index value reuse logic
properly distinguish types of frame values (e.g., whether the value is
stack-pointer relative or frame-pointer relative).

No functionality change.

Chris Lattner f98f124a73 Sink InstructionSelect() out of each target into SDISel, and rename it
DoInstructionSelection.  Inline "SelectRoot" into it from DAGISelHeader.
Sink some other stuff out of DAGISelHeader into SDISel.

Eliminate the various 'Indent' stuff from various targets, which dates
to when isel was recursive.

Sanjiv Gupta 7828ff9535 Currently in LLVM, names of libcalls are assigned during TargetLowering
object construction. There is no provision to change them when the 
code for a function generated. 
So we have to change these names while printing assembly.

Sanjiv Gupta 84a85fcb91 Initial implementation of PIC16 Cloner pass.
This pass is supposed to be run on the linked .bc module.
It traveses the module call graph twice. Once starting from the main function
and marking each reached function as "ML". Again, starting from the ISR
and cloning any reachable function that was marked as "ML". After cloning
the function, it remaps all the call sites in IL functions to call the
cloned functions. 

Currently only marking is being done.

Evan Cheng 5e73ff2e3a Split SelectionDAGISel::IsLegalAndProfitableToFold to
IsLegalToFold and IsProfitableToFold. The generic version of the later simply checks whether the folding candidate has a single use.

This allows the target isel routines more flexibility in deciding whether folding makes sense. The specific case we are interested in is folding constant pool loads with multiple uses.

Evan Cheng 67a69dd2ed Eliminate target hook IsEligibleForTailCallOptimization.
Target independent isel should always pass along the "tail call" property. Change
target hook LowerCall's parameter "isTailCall" into a refernce. If the target
decides it's impossible to honor the tail call request, it should set isTailCall
to false to make target independent isel happy.
