Adjust derived classes to pass UnknownLoc where
a DebugLoc does not make sense.  Pick one of
DebugLoc and non-DebugLoc variants to survive
for all such classes.

Don't sink the instruction if TargetRegisterInfo::isSafeToMoveRegClassDefs doesn't think it's safe. This works around PR1911.

Many targets build placeholder nodes for special operands, e.g.
GlobalBaseReg on X86 and PPC for the PIC base.  There's no
sensible way to associate debug info with these.  I've left
them built with getNode calls with explicit DebugLoc::getUnknownLoc operands. 
I'm not too happy about this but don't see a good improvement;
I considered adding a getPseudoOperand or something, but it
seems to me that'll just make it harder to read.

getCALLSEQ_{END,START} to permit passing no DebugLoc
there.  UNDEF doesn't logically have DebugLoc; add
getUNDEF to encapsulate this.

A simple test program shows that debugging works. :-)

SelectionDAGISel::CreateScheduler, and make it just create the
scheduler. Leave running the scheduler to the higher-level code.
This makes the higher-level code a little more explicit and
easier to follow, and will help enable some future refactoring.

that previously included this header should include
SchedulerRegistry.h instead.

llvm-svn: 63937

Add TargetInstrInfo::isSafeToMoveRegisterClassDefs. It returns true if it's safe to move an instruction which defines a value in the register class. Replace pre-splitting specific IgnoreRegisterClassBarriers with this new hook.

llvm-svn: 63936

that used this header to select a scheduling policy should
use SchedulerRegistry.h instead (llvm-gcc and clang were
updated a while ago).

its corresponding getTargetNode.  Lots of

Refactor my previous change to maintain the distinction between AliasAnalysis and BasicAliasAnalysis.  This involves some wider changes because it
folds away some never-used methods.

Ignore dbg intrinsics while propagating conditional expression info. Take 2.

isAsCheapAsMove instructions can have register src operands. Check if they are really re-materializable.
This fixes sse.expandfft and sse.stepfft.
