68040 and 68060 owners.
With ``make M68040=1'' or ``make M68060=1'', we build a libc where the ldexp()
doesn't use excessive amounts of system cpu time.
Without any of those defines, the normal assembler version using FSCALE is
included, for the benefit of M68020 and M68030 users, or M68040/M68060 users
where the ldexp performance is no bottleneck.
[Its not yet worked out how to include both library versions in a binary
distribution, but you can build your own from source now if you need it.]
For details, look at PR 3105.
tsleep() to be called from an interrupt handler.
The semantics of the scroll-lock key is changed now: it issues a ^S or
^Q, depending on the current state. (It should probably issue
tp->t_cc[VSTOP] or tp->t_cc[VSTART] instead, but this would require more
serious structural changes because there is not always a tty context
present.)
The "scroll lock" LED is now controlled by pcstart()/pcstop(), so it
will show the real state even if the start/stop characters are remapped
or the normal ^S/^Q are used.
about actual position when reading tape position, you should flush any
pending writes. Well, if the tape is write protected, some drives don't
see the zero count WRITE FILE MARK command as a no-op and complain. Dumb!
Add newer Intel / VIA i386 chipsets.
Correct one S3 chip, add one.
Mostly from Carl Shapiro <css@samsara.dialup.access.net> per PR kern/4169
and kern/4170 (identical).
memref_referenced_p(); otherwise there are cases where a later set that changes
the memory location may be moved too early, and thus the new value will be
(incorrectly) used where it should not be.
