This is a work in progress.

not all unary nodes necessarily have a simple result type.

llvm-svn: 98547

MCSectionMachO is already fine (yay for fixed size arrays?),
MCSectionCOFF still leaks.

with ppc_f128 type by having the type legalizer turn these back into a
call to copysignl.

llvm-svn: 98512

no functionality change.

label instead of trying to form one based on the BB name (which
causes collisions if the name is empty).  This fixes PR6608

llvm-svn: 98495

to get unique assembler temporary labels.

contain an MCSymbol instead of a label index.

with an MCSymbol instead of an immediate.

llvm-svn: 98481

llvm-svn: 98477

not from MMI.

llvm-svn: 98475

llvm-svn: 98474

llvm-svn: 98471

an MCSymbol.  Make the EH_LABEL MachineInstr hold its label
with an MCSymbol instead of ID.  Fix a bug in MMI.cpp which
would return labels named "Label4" instead of "label4".

llvm-svn: 98463

them with a counter.

llvm-svn: 98462

consistently use MCSymbol and only call this predicate after
they should have been emitted.

llvm-svn: 98461

instead of label ID's.  This cleans up and regularizes a bunch 
of code and makes way for future progress.

Unfortunately, this pointed out to me that JITDwarfEmitter.cpp
is largely copy and paste from DwarfException/MachineModuleInfo
and other places.  This is very sad and disturbing. :(

One major change here is that TidyLandingPads moved from being
called in DwarfException::BeginFunction to being called in
DwarfException::EndFunction.  There should not be any 
functionality change from doing this, but I'm not an EH expert.

llvm-svn: 98459

llvm-svn: 98451

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.

llvm-svn: 98450

llvm-svn: 98433

instead of as a stem+idx pair, simplify the "is a new 
location" check to use symbol comparison.

llvm-svn: 98432

llvm-svn: 98429

entries to not thrash std::strings and MCSymbols.
