The fallback implementation of "ret = 0 - arg1" isn't ideal,
first because of the extra tcg op to load the zero, and second
because we fail to handle zero as %g0 for arg1 of the sub.

All of these patches are toward reducing the number of TCG opcodes
generated. Three of the patches reduce the number of real insns
generated as well. The ANDC and ORC opcodes are already generated
by the ARM, PPC, and Alpha translators.

Nope, not found on FreeBSD. (Also I would kinda doubt that sysctl is

_CALL_SYSV means that calling convention is SysV one, nothing to do with

If a write requests crosses a L2 table boundary and all clusters until the
end of the L2 table are usable for the request, we must not look at the next

Hi all,
Does QEMU provide emulation for any target with USB device controller? Actually
I am developing an embedded linux based device and was thinking about testing
it on QEMU.

If the device can't be created, don't leak the QemuOpts and release the id of
the device that should have been added by the failed device_add.

How much improvement are we talking here?
Is it still faster when a bswap is involved?
Thanks for pointing out.
I will post the data for x86 later.
However, I don't have a test environment to check the impact of bswap.

The attached patches here add support for pselect call emulation in linux-user
and also add the proper entry to the ARM architecture syscall lists.
There is some code duplication between do_select() and do_pselect() to handle
copying the file descriptors over from the target to host; this could be
