Hum. That does cause a problem.
No objection to the patch approve

OK.

Surely optimize_insn_for_size_p (), so that cold blocks are optimized for size.

We're now getting the insn type and thus length wro

Hello,
Here is a fix for PR 50962. Fix improves AGU stall avoidance
optimization by adding opportunity to emit lea instead of mov when it
is profitable.
Bootstrapped and checked on linux-x86_64.
Could please someone review it?
Thanks,
