Hello Yunfeng,
Thank you for following up, and sorry for me reviewing your patches so
lately. The libcpp changes are coming along nicely, IMHO. I like the
fact that they are getting pretty minimal. I just have a few mostly

This patch tried to use non-clearing memory allocation where possible.

This fixes one issue with copyrename, that it leaks names backward
through a PHI node because it treats a PHI node
_1 = PHI _2, _3, _4
as
_1 = _2;
_1 = _3;
_1 = _4;
at the point of the PHI node which is certainly not what it is
(the assigns exist, one each, on the incoming edges only).

Yes, it is a bug. It's a bit disturbing that it wasn't caught

You'll recall that I pointed it out last time around as well.

Hello!
It is known that LEA splitting is one of the most critical problems
for Atom processors and changes try to improve it through:

Hello,
This adds support for the SH2A instructions movu.b and movu.w for
zero-extending mem loads with displacement addressing.
Tested on rev 190332 with

\{-m2/-ml,-m2/-mb,-m2a/-mb,-m4/-ml,-m4/-mb,-m4a/-ml,-m4a/-mb}
and no new failures.
OK?

move_unallocated_pseudos apparently relies on no insns being deleted

delete_trivially_dead_insns removes dead insns and insns that feed them.
This can be fixed either by moving

Thanks for your work on this. This is a big step. I would add to your

Ok.

I think there are a couple of bugs not triggered by the single component

Yes, you are right. We should have tested multiple components... my fault!
