Eli Friedman 6b7bb42c36 Mark a few Thumb instructions commutable; just happened to spot this ...

while experimenting.  I'm reasonably sure this is correct, but please 
tell me if these instructions have some strange property which makes this
change unsafe.

2009-06-04-MissingLiveIn.ll

A value defined by an implicit_def can be liven to a use BB. This is unfortunate. But register allocator still has to add it to the live-in set of the use BB.

2009-06-04 20:25:48 +00:00

2009-06-12-RegScavengerAssert.ll

If killed register is defined by implicit_def, do not clear it since it's live range may overlap another def of same register.

2009-06-12 21:34:26 +00:00

2009-06-15-RegScavengerAssert.ll

If a val# is defined by an implicit_def and it is being removed, all of the copies off the val# were removed. This causes problem later since the scavenger will see uses of registers without defs. The proper solution is to change the copies into implicit_def's instead.
