David Greene ec9bc28812 Re-apply LiveInterval index dumping patch, with fixes suggested by Bill 
and others.

 2009-08-03 21:55:09 +00:00

LiveInterval, etc to raw_ostream.

David Greene 3b458645be Add PrefixPrinter arguments to the dump routines for MachineFunction and 
MachineBasicBlock.  We'll use these shortly.

Dan Gohman bb2f10759e If a MachineBasicBlock has multiple ways of reaching another block, 
allow it to have multiple CFG edges to that block. This is needed
to allow MachineBasicBlock::isOnlyReachableByFallthrough to work
correctly. This fixes PR4126.

llvm-svn: 71018
 2009-05-05 21:10:19 +00:00
Dan Gohman 6b42dfddf4 Reapply 68073, with fixes. EH Landing-pad basic blocks are not 
entered via fall-through. Don't miss fallthroughs from blocks
terminated by conditional branches. Also, move
isOnlyReachableByFallthrough out of line.

llvm-svn: 68129

Dan Gohman 0d1e9a8e04 Switch the MachineOperand accessors back to the short names like 
isReg, etc., from isRegister, etc.

llvm-svn: 57006
 2008-10-03 15:45:36 +00:00
Dan Gohman a78bae34a5 Add a new MachineBasicBlock utility function, isLayoutSuccessor, that 
can be used when deciding if a block can transfer control to another
via a fall-through instead of a branch.

llvm-svn: 56968
 2008-10-02 22:09:09 +00:00
Dan Gohman 38453eebdc Remove isImm(), isReg(), and friends, in favor of 
isImmediate(), isRegister(), and friends, to avoid confusion
about having two different names with the same meaning. I'm
not attached to the longer names, and would be ok with
changing to the shorter names if others prefer it.

Dan Gohman 804c95df52 Fold the useful features of alist and alist_node into ilist, and 
a new ilist_node class, and remove them. Unlike alist_node,
ilist_node doesn't attempt to manage storage itself, so it avoids
the associated problems, including being opaque in gdb.

Adjust the Recycler class so that it doesn't depend on alist_node.
Also, change it to use explicit Size and Align parameters, allowing
it to work when the largest-sized node doesn't have the greatest
alignment requirement.

Change MachineInstr's MachineMemOperand list from a pool-backed
alist to a std::list for now.

Dan Gohman 0ece943845 Re-introduce LeakDetector support for MachineInstrs and MachineBasicBlocks. 
Fix a leak that this turned up in LowerSubregs.cpp.
And, comment a leak in LiveIntervalAnalysis.cpp.

Dan Gohman 3b46030375 Pool-allocation for MachineInstrs, MachineBasicBlocks, and 
MachineMemOperands. The pools are owned by MachineFunctions.

This drastically reduces the number of calls to malloc/free made
during the "Emit" phase of scheduling, as well as later phases
in CodeGen. Combined with other changes, this speeds up the
"instruction selection" phase of CodeGen by 10% in some cases.

Evan Cheng 3980a7911a - Check if a register is livein before removing it. It may have already been removed. 
- Do not iterate over SmallPtrSet, the order of iteration is not deterministic.

Chris Lattner 03ad885039 rename TargetInstrDescriptor -> TargetInstrDesc. 
Make MachineInstr::getDesc return a reference instead
of a pointer, since it can never be null.

llvm-svn: 45695
 2008-01-07 07:27:27 +00:00
Chris Lattner a98c679de0 Rename MachineInstr::getInstrDescriptor -> getDesc(), which reflects 
that it is cheap and efficient to get.

Move a variety of predicates from TargetInstrInfo into 
TargetInstrDescriptor, which makes it much easier to query a predicate
when you don't have TII around.  Now you can use MI->getDesc()->isBranch()
instead of going through TII, and this is much more efficient anyway. Not
all of the predicates have been moved over yet.

Update old code that used MI->getInstrDescriptor()->Flags to use the
new predicates in many places.

Chris Lattner 961e7427ea Implement automatically updated def/use lists for all MachineInstr register 
operands.  The lists are currently kept in MachineRegisterInfo, but it does
not yet provide an iterator interface to them.

Chris Lattner 574e7166e0 properly encapsulate the parent field of MBB and MI with get/set accessors. 
llvm-svn: 45469
 2007-12-31 04:56:33 +00:00
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.
