Evan Cheng b5f0ec3eb7 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.

Dan Gohman f4b08b4f6c Move ScheduleDAGInstrs.h to be a private header. Front-ends 
that used this header to select a scheduling policy should
use SchedulerRegistry.h instead (llvm-gcc and clang were
updated a while ago).

Dan Gohman 87cab1e751 Tidy up the ScheduleDAG class definition a little. Make a few 
more member functions protected, and group all the protected
members together.

Zhongxing Xu e42755334c SymbolicRegions really have unknown sizes. 
llvm-svn: 63929
 2009-02-06 08:51:30 +00:00
Zhongxing Xu dec48a50df Create ElementRegion when the base is SymbolicRegion. This is like what we do 
for FieldRegion. This enables us to track more values.

Simplify SymbolicRegion::getRValueType(). We assume the symbol always has
pointer type.

Owen Anderson 98a3617fba 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.

Douglas Gregor eff93e0401 Improve the representation of template type parameters. We now 
canonicalize by template parameter depth, index, and name, and the
unnamed version of a template parameter serves as the canonical.

TemplateTypeParmDecl no longer needs to inherit from
TemplateParmPosition, since depth and index information is present
within the type.
