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. :-)

re-acquire the lock.

Deallocate() methods now take a 'const void*' instead of a 'void *', matching observed behavior with how 'delete[]' can be used.

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.

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.

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

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.
