Chris Lattner a5bb370aa4 Add new shorter predicates for testing machine operands for various types: 
e.g. MO.isMBB() instead of MO.isMachineBasicBlock().  I don't plan on 
switching everything over, so new clients should just start using the 
shorter names.

Remove old long accessors, switching everything over to use the short
accessor: getMachineBasicBlock() -> getMBB(), 
getConstantPoolIndex() -> getIndex(), setMachineBasicBlock -> setMBB(), etc.

Chris Lattner 6005589faf More cleanups for MachineOperand: 
- Eliminate the static "print" method for operands, moving it
    into MachineOperand::print.
  - Change various set* methods for register flags to take a bool
    for the value to set it to.  Remove unset* methods.
  - Group methods more logically by operand flavor in MachineOperand.h

Chris Lattner c98c0e57eb MachineOperand: 
- Add getParent() accessors.
  - Move SubReg out of the AuxInfo union, to make way for future changes.
  - Remove the getImmedValue/setImmedValue methods.
  - in some MachineOperand::Create* methods, stop initializing fields that are dead.

MachineInstr:
  - Delete one copy of the MachineInstr printing code, now there is only one dump
    format and one copy of the code.
  - Make MachineOperand use the parent field to get info about preg register names if
    no target info is otherwise available.
  - Move def/use/kill/dead flag printing to the machineoperand printer, so they are
    always printed for an operand.

Duncan Sands e9d8861cdf Simplify LowerCallTo by using a callsite. 
llvm-svn: 45198
 2007-12-19 09:48:52 +00:00
Duncan Sands 030bce7b83 The C++ exception handling personality function wants 
to know about calls that cannot throw ('nounwind'):
if such a call does throw for some reason then the
personality will terminate the program.  The distinction
between an ordinary call and a nounwind call is that
an ordinary call gets an entry in the exception table
but a nounwind call does not.  This patch sets up the
exception table appropriately.  One oddity is that
I've chosen to bracket nounwind calls with labels (like
invokes) - the other choice would have been to bracket
ordinary calls with labels.  While bracketing
ordinary calls is more natural (because bracketing
by labels would then correspond exactly to getting an
entry in the exception table), I didn't do it because
introducing labels impedes some optimizations and I'm
guessing that ordinary calls occur more often than
nounwind calls.  This fixes the gcc filter2 eh test,
at least at -O0 (the inliner needs some tweaking at
higher optimization levels).

Christopher Lamb edf0788758 Change the PointerType api for creating pointer types. The old functionality of PointerType::get() has become PointerType::getUnqual(), which returns a pointer in the generic address space. The new prototype of PointerType::get() requires both a type and an address space.
