Hi folks,
Can someone perform a bench to see if a four-instruction immediate load
sequence can outperform GOT or vice versa? I cannot access my test
system in at least 1 week, and I may be busy preparing Linux From
Scratch 11.2 release in the remaining of August.
Note: if the four-instruction immediate load sequence outperforms GOT,
we should consider use immediate load instead of GOT for -fno-PIC by
default.
P.S. It seems I have trouble accessing gcc400.fsffrance.org. I have a C
Farm account and I've already put
Host gcc400.fsffrance.org
Port 25465
in ~/.ssh/config, and I can access other C farm machines w/o problem.
But:
$ ssh gcc400.fsffrance.org
xry...@gcc400.fsffrance.org: Permission denied
(publickey,keyboard-interactive).
If you know the administrator of the C farm machine, can you tell him to
check the configuration? If I can access it I may use some time to
perform the bench (in userspace of course) myself. Thanks.
