into a header for reuse in crt0.o for static ifunc support. Change the
existing logic for sparc64 to use the Bicc variant of ba,a as it allows
+-8MB displacement compared to the BPcc variant's +-1MB. Teach the sparc
variant the same trick for using ba,a and not sethi+jmp when possible.
Add soroverflow() which increments the overflow counter, sets so_error
to ENOBUFS and wakes the receive socket up.
Replace all code that manually increments this counter with soroverflow().
Add soroverflow() to raw_input().
This allows userland to detect route(4) overflows so it can re-sync
with the current state.
As a component of atan2(y, x), the case of x == 1.0 is farmed out to
atan(y). The current implementation of this comparison is vulnerable
to signed integer underflow (that is, undefined behavior), and it's
performed in a somewhat more complicated way than it need be. Change
it to not be quite so cute, rather directly comparing the high/low
bits of x to the specific IEEE-754 bit pattern that encodes 1.0.

These operations cloned Linux's specific PTRACE_GETSIGMASK / PTRACE_SETSIGMASK.
This feature was useful in applications like rr/criu/reptyr-like, where
the ptrace(2) interface is abused for the purpose of constructing an arbitrary
process. It's not reliable and not portable. For the NetBSD case it will be
better to invent something dedicated for serializing and deserializing a
process with threads.

more function calls after restore.
(oops, forgot to commit this along with swapcontext.S)
These functions were marked as _NETBSD_SOURCE when introduced to the
sources. In fact they are regular POSIX threading functions available
since the 2001 standard. There is an older mention about alignment with
"IEEE Std 1003.1j-2000".
This corrects usage of these functions when a source code is compiled
with a POSIX namespace option.
Fixes SIGINT causing ksh to "longjmp botch", presumably due to incorrect
magic number.

Discussed on tech-kern@ three weeks ago. The original issue was reported
by maya@, the patch was written by Tom Ivar Helbekkmo, ok christos@.
- -Wstrict-prototypes is not available for C++, so don't try to
ignore it for C++.
- remove many _DIAGASSERT() checks against not NULL for functions
with arguments with nonnull attributes. in two cases, leave
code behind that should set defaults to "(null)".
- use -Wno-error=frame-address for i386 mcount, as it seems valid
to assume the caller will have a frame.fair
Release 2018c - 2018-01-22 23:00:44 -0800
Changes to build procedure
The build procedure now works around mawk 1.3.3's lack of support
for character class expressions. (Problem reported by Ohyama.)
Release 2018b - 2018-01-17 23:24:48 -0800
Changes to build procedure
The distribution now contains the file 'pacificnew' again.
This file was inadvertantly omitted in the 2018a distribution.
(Problem reported by Matias Fonzo.)
Release 2018a - 2018-01-12 22:29:21 -0800
Changes to build procedure
The default installation locations have been changed to mostly
match Debian circa 2017, instead of being designed as an add-on to
4.3BSD circa 1986. This affects the Makefile macros TOPDIR,
TZDIR, MANDIR, and LIBDIR. New Makefile macros TZDEFAULT, USRDIR,
USRSHAREDIR, BINDIR, ZDUMPDIR, and ZICDIR let installers tailor
locations more precisely. (This responds to suggestions from
Brian Inglis and from Steve Summit.)
The default installation procedure no longer creates the
backward-compatibility link US/Pacific-New, which causes
confusion during user setup (e.g., see Debian bug 815200).
Use 'make BACKWARD="backward pacificnew"' to create the link
anyway, for now. Eventually we plan to remove the link entirely.
tzdata.zi now contains a version-number comment.
(Suggested by Tom Lane.)
The Makefile now quotes values like BACKWARD more carefully when
passing them to the shell. (Problem reported by Zefram.)
Builders no longer need to specify -DHAVE_SNPRINTF on platforms
that have snprintf and use pre-C99 compilers. (Problem reported
by Jon Skeet.)
Changes to code
zic has a new option -t FILE that specifies the location of the
file that determines local time when TZ is unset. The default for
this location can be configured via the new TZDEFAULT makefile
macro, which defaults to /etc/localtime.
Diagnostics and commentary now distinguish UT from UTC more
carefully; see theory.html for more information about UT vs UTC.
zic has been ported to GCC 8's -Wstringop-truncation option.
(Problem reported by Martin Sebor.)
Changes to documentation and commentary
The zic man page now documents the longstanding behavior that
times and years can be out of the usual range, with negative times
counting backwards from midnight and with year 0 preceding year 1.
(Problem reported by Michael Deckers.)
The theory.html file now mentions the POSIX limit of six chars
per abbreviation, and lists alphabetic abbreviations used.
The files tz-art.htm and tz-link.htm have been renamed to
tz-art.html and tz-link.html, respectively, for consistency with
other file names and to simplify web server configuration.
"Include namespace.h in a few of libc source files
[...]
This change finishes elimination of usage of the global name of the
following symbols:
- close -> _close
- execve -> _execve
- fcntl -> _fcntl
- setcontext -> _setcontext
- wait6 -> _wait6
- write -> _write
- writev -> _writev"
"Register more syscalls in namespace.h (of libc)
Add weak symbols for:

This revert fixes the failures, except lib/librumphijack/t_vfs.
The original changes were added in order to facilitate a usage of
sanitizers against programs linked with NetBSD's libc. It is no longer
needed, so abandon these changes.
