Sean Callanan [Wed, 15 Aug 2012 20:53:52 +0000 (20:53 +0000)]
Fixed a problem in the JIT memory allocator where
allocations of executable memory would not be padded
to account for the size of the allocation header.
This resulted in undersized allocations, meaning that
when the allocation was written to later the next
allocation's header would be corrupted.

Jakob Stoklund Olesen [Mon, 13 Aug 2012 21:52:57 +0000 (21:52 +0000)]
Remove the TII::scheduleTwoAddrSource() hook.

It never does anything when running 'make check', and it get's in the
way of updating live intervals in 2-addr.

The hook was originally added to help form IT blocks in Thumb2 code
before register allocation, but the pass ordering has changed since
then, and we run if-conversion after register allocation now.

When the MI scheduler is enabled, there will be no less than two
schedulers between 2-addr and Thumb2ITBlockPass, so this hook is
unlikely to help anything.
