Dan Gohman	b95434356c	Factor out more code for computing register live-range informationfor scheduling, and generalize is so that preserves state across scheduling regions. This fixes incorrect live-range information around terminators and labels, which are effective region boundaries. In place of looking for terminators to anchor inter-block dependencies, introduce special entry and exit scheduling units for this purpose. llvm-svn: 64254	2009-02-10 23:27:53 +00:00
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). llvm-svn: 63934	2009-02-06 17:12:10 +00:00

Factor out more code for computing register live-range informationfor

scheduling, and generalize is so that preserves state across
scheduling regions. This fixes incorrect live-range information around
terminators and labels, which are effective region boundaries.

In place of looking for terminators to anchor inter-block dependencies,
introduce special entry and exit scheduling units for this purpose.

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).
