Hi!
For -fnon-call-exceptions, if an instruction with REG_EH_REGION note is
reloaded, we should copy or move it to the instruction(s) corresponding to
the original one that could throw. reload1.c apparently does this, but LRA
does not, so we can end up with REG_EH_REGION notes being dropped, or not
present on insns that actually can throw etc.
Fixed by calling the functions reload1.c does for this purpose.
Bootstrapped/regtested on x86_64-linux (including Ada) and i686-linux
(without Ada), and Dominik has kindly tested this on s390x-linux
(presumably with Ada, but don't know for sure). Ok for trunk?
Yes. Thanks, Jakub.
