entry point has been replaced by the new __sigaction14() which is a
wrapper around the __sigaction_sigtramp system call (which is itself
not directly exposed outside of libc).
No shared library version change is necessary; no new symbols
are exposed outside of libc.
now be displayed correctly (fixes part 1 of pr 17480)
* Prevent field manipulations on null fields, the fields have nothing in
them so they should not be manipulated.
SH-5, meet NetBSD.
Let's hope this is the start of a long and fruitful relationship. :-)
This code, funded by Wasabi Systems, adds initial support for the
Hitachi SuperH(tm) SH-5 cpu architecture to NetBSD.
At the present time, NetBSD/evbsh5 only runs on a SH-5 core simulator
which has no simulated devices other than a simple console. However, it
is good enough to get to the "root device: " prompt.
Device driver support for Real SH-5 Hardware is in place, particularly for
supporting the up-coming Cayman evaluation board, and should be quite
easy to get running when the hardware is available.
There is no in-tree toolchain for this port at this time. Gcc-current has
rudimentary SH-5 support but it is known to be buggy. A working toolchain
was obtained from SuperH to facilitate this port. Gcc-current will be
fixed in due course.
The SH-5 architecture is fully 64-bit capable, although NetBSD/evbsh5 has
currently only been tested in 32-bit mode. It is bi-endian, via a boot-
time option and it also has an "SHcompact" mode in which it will execute
SH-[34] user-land instructions.
For more information on the SH-5, see www.superh.com. Suffice to say it
is *not* just another respin of the SH-[34].
sysconf(_SC_CLK_TCK) return hz will work.
In detail:
__times13() returns values scaled by hz.
times() returns values scaled by 100.
<sys/times.h> renames times() to __times13().
_SC_CLK_TCK has changed from 3 to 39.
sysconf(3) returns 100.
sysconf(39) returns hz.
CLK_TCK is defined as sysconf(39).
sidestep it using troff macro trick from FreeBSD version of this manpage.

This fixes lib/12260 by Ada Lim and lib/17406 by Greg A. Woods.
correct bad practice in the code - it uses two changing variables
to manage buffer (buf and buflen). we eliminate buflen and use
fixed point (ep) as the ending pointer.
this fix is critical.
ticks. Although the two are the same, SuS now says you use the former,
not the latter, to get the information. Also, fill in a little
information on just how awful this crusty wreck is.
