r315034:
Document that the msun tests require WARNS=0

ATF tests have a default WARNS of 0, unlike other usermode programs. This
change is technically a noop, but it documents that the msun tests don't
work with any warnings enabled, at least not on all architectures.

r311925:

Import testcase updates with code contributed back to NetBSD

This also (inadvertently) contains an update to
contrib/netbsd-tests/lib/libc/sys/t_wait.c (new testcases).

In collaboration with: christos@NetBSD.org

r311968:

Fix lib/libc/sys/access_test after r311925

sys/param.h needs to be #included in order for __FreeBSD_version to be checked

r311969:

Remove __HAVE_LONG_DOUBLE #define from t_strtod.c and place it in Makefile

This is to enable support in other testcases

Inspired by lib/msun/tests/Makefile .

r312008:

Upgrade NetBSD tests to 01.11.2017_23.20 snapshot

This contains some new testcases in /usr/tests/...:

- .../lib/libc
- .../lib/libthr
- .../lib/msun
- .../sys/kern

Tested on: amd64, i386

MFC r305358,r305449,r305451,r306367,r306397,r309474:

This also contains a merge of ^/projects/netbsd-tests-update-12@r304035 .
This change never hit ^/head because bin/cat's behavior was changed (on ^/head)
to match NetBSD.

PR: 210607

r305358:

Update contrib/netbsd-tests with new content from NetBSD

This updates the snapshot from 09/30/2014 to 08/11/2016

This brings in a number of new testcases from upstream, most
notably:

- bin/cat
- lib/libc
- lib/msun
- lib/libthr
- usr.bin/sort

lib/libc/tests/stdio/open_memstream_test.c was moved to
lib/libc/tests/stdio/open_memstream2_test.c to accomodate
the new open_memstream test from NetBSD.

Tested on: amd64 (VMware fusion VM; various bare metal platforms); i386 (VMware fusion VM); make tinderbox

r305449:

Install h_db to unbreak some of the lib/libc/db testcases after
r305358

r305451:

Fix lib/libc/rpc test assumptions added in r305358

- Require root in the tcp/udp subtests (it's needed on FreeBSD when
registering services).
- Skip the tests if service registration fails.

r306367 (by br):

Allow up to 6 arguments only on MIPS.

r306397 (by br):

Use right piece of code for FreeBSD.

r309474:

Don't build :strvis_locale if VIS_NOLOCALE is undefined

The copy of contrib/libc-vis on ^/stable/10 doesn't contain all of the features
in the ^/stable/11 // ^/head version, including VIS_NOLOCALE. The risk is lower
in conditionally running the test instead of backporting the newer version of
libc-vis

r289172:

Refactor the test/ Makefiles after recent changes to bsd.test.mk (r289158) and
netbsd-tests.test.mk (r289151)

- Eliminate explicit OBJTOP/SRCTOP setting
- Convert all ad hoc NetBSD test integration over to netbsd-tests.test.mk
- Remove unnecessary TESTSDIR setting
- Use SRCTOP where possible for clarity

r290254:

Remove unused variable (SRCDIR)

MFC r297836:

Fix appending -O0 to CFLAGS

The previous method would completely nerf CFLAGS once bsd.progs.mk had
recursed into the per-PROG logic and make the CFLAGS for tap testcases
to -O0, instead of appending to CFLAGS for all of the tap testcases.

MFC r292497:

Integrate the remaining tools/regression/lib/msun testcases into the
FreeBSD test suite under lib/msun/tests

MFC r292328:

Integrate a number of testcases from tools/regression/lib/msun
into the FreeBSD test suite

There's no functional change with these testcases; they're purposely
being left in TAP format for the time being

Other testcases which crash on amd64/i386 as-is have not been
integrated yet (they need to be retested on a later version of
CURRENT, as I haven't used i386 in some time)

r282092 (by andrew):

Correct the spelling of MACHINE_CPUARCH, MACHINE_CPU is not set on arm64.

r282106:

Remove per-architecture checks for enabling HAVE_FENV_H

The conditional came from NetBSD, where only select architectures have this
header/support

All architectures on FreeBSD have the necessary support though, so the
conditional's completely unnecessary

make tinderbox done on all architectures (including arm64, where the issue
occurred before) this time
