RTL pass
An updated patch that adds an SH specific RTL pass against current trunk (rev
202873), not fully tested.
CSiBE for '-m2a-single -O2' and '-m4-single -mpretend-cmove -O2' look OK.
There are only 2 cases that got actually worse in the set:
linux-2.4.23-pre3-testplatform/fs/lockd/host.s (nlm_lookup_host):
