Dan Gohman 3a4be0fdef Rename MRegisterInfo to TargetRegisterInfo. 
llvm-svn: 46930

Chris Lattner 596875118c rename MachineInstr::setInstrDescriptor -> setDesc

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

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.

Devang Patel 8c78a0bff0 Drop 'const' 
llvm-svn: 36662
 2007-05-03 01:11:54 +00:00
Devang Patel e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

Devang Patel 09f162ca6a Do not use typeinfo to identify pass in pass manager.

Evan Cheng f030f2d628 Only safe to use a call-clobbered or spilled callee-saved register as scratch register.
