ARM assembly parsing and encoding for BLX (immediate).

Add parsing support for BLX (immediate). Since the register operand version is
predicated and the label operand version is not, we have to use some special
handling to get the operand list right for matching.

'atomicrmw' instructions, which allow representing all the current atomic

The allowed operands for these instructions are heavily restricted at the
moment; we can probably loosen it a bit, but supporting general
first-class types (where it makes sense) might get a bit complicated,

As an initial cut, these operations do not support specifying an alignment,
but it would be possible to add if we think it's useful. Specifying an
alignment lower than the natural alignment would be essentially
impossible to support on anything other than x86, but specifying a greater
alignment would be possible.  I can't think of any useful optimizations which

13 years agoReverse order of RS_Split live ranges under -compact-regions.
Jakob Stoklund Olesen [Thu, 28 Jul 2011 20:48:23 +0000 (20:48 +0000)]
Reverse order of RS_Split live ranges under -compact-regions.

There are two conflicting strategies in play:

- Under high register pressure, we want to assign large live ranges
  first. Smaller live ranges are easier to place afterwards.

- Live range splitting is guided by interference, so splitting should be
  deferred until interference is as realistic as possible.

With the recent changes to the live range stages, and with compact
regions enabled, it is less traumatic to split a live range too early.
If some of the split products were too big, they can often be split
again.

By reversing the RS_Split order, we get this queue order:

1. Normal live ranges, large to small.
2. RS_Split live ranges, large to small.

The large-to-small order improves RAGreedy's puzzle solving skills under
high register pressure. It may cause a bit more iterated splitting, but
we handle that better now.

With this change, -compact-regions is mostly an improvement on SPEC.
