Evan Cheng [Mon, 1 May 2006 09:14:40 +0000 (09:14 +0000)]
Bottom up register-pressure reduction scheduler now pushes store operations
up the schedule. This helps code that looks like this:

loads ...
computations (first set) ...
stores (first set) ...
loads
computations (seccond set) ...
stores (seccond set) ...

Without this change, the stores and computations are more likely to
interleave:

loads ...

Fix some nondeterminstic behavior in the mem2reg pass that (in addition to
nondeterminism being bad) could cause some trivial missed optimizations (dead
phi nodes being left around for later passes to clean up).

With this, llvm-gcc4 now bootstraps and correctly compares.  I don't know
why I never tried to do it before... :)
