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.

Bruno Cardoso Lopes d6fff557db First step towards varargs support in Mips:
- o32 cc must pass all arguments in A0...A3 and stack regardless
if its type (but respect the alignment).
- Store all variable arguments back to the caller stack.

Chris Lattner 996ec840d0 rejigger the world so that EmitInstruction prints the \n at

Chris Lattner 94a946cac4 Remove the argument from EmitJumpTableInfo, because it doesn't need it.

AsmPrinter::EmitFunctionBody, which works by calling the virtual
EmitInstruction method.

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.

Chris Lattner ff234e09b9 Eliminate SetDirective, and replace it with HasSetDirective.
Default HasSetDirective to true, since most targets have it.

The targets that claim to not have it probably do, or it is
spelled differently. These include Blackfin, Mips, Alpha, and
PIC16.  All of these except pic16 are normal ELF targets, so
they almost certainly have it.

Chris Lattner 7ba0661f27 Stop building RTTI information for *most* llvm libraries. Notable
missing ones are libsupport, libsystem and libvmcore.  libvmcore is
currently blocked on bugpoint, which uses EH.  Once it stops using
EH, we can switch it off.

This #if 0's out 3 unit tests, because gtest requires RTTI information.
Suggestions welcome on how to fix this.

Chris Lattner 2b4364fe03 revert 93934, removing the MCAsmInfo endianness bit. I can't
stomache MCAsmInfo having this, and I found a better solution to
this layering issue.

llvm-svn: 93985
2010-01-20 06:34:14 +00:00
Chris Lattner 003b5c8472 give MCAsmInfo a 'has little endian' bit. This is unfortunate, but
I really want clients of the streamer to be able to say "emit this
64-bit integer" and have it get broken down right by the streamer.

I may change this in the future, we'll see how it works out.

Chris Lattner c7a062d187 Now that we have everything nicely factored (e.g. asmprinter is not
doing global variable classification anymore) and hookized, sink almost
all target targets global variable emission code into AsmPrinter and out
of each target.

Some notes:

1. PIC16 does completely custom and crazy stuff, so it is not changed.
2. XCore has some custom handling for extra directives.  I'll look at it next.
3. This switches linux/ppc to use .globl instead of .global.  If .globl is
   actually wrong, let me know and I'll fix it.
4. This makes linux/ppc get a lot of random cases right which were obviously
   wrong before, it is probably now a bit healthier.
5. Blackfin will probably start getting .comm and other things that it didn't
   before.  If this is undesirable, it should explicitly opt out of these
   things by clearing the relevant fields of MCAsmInfo.

This leads to a nice diffstat:

Chris Lattner 8b5d55ed06 now that MCSymbol::print doesn't use it's MAI argument, we can
