No need to use movq for the small immediate values here, they'll be
...
zero-extended with movl.

Implement pthread_atfork() (in libc, because the required threadlib
...
stub behavior is exactly the same as the usual behavior).

Add ucontext glue for x86_64.

These files are obsolete; setlogin() is now implemented in C with a
...
small syscall stub.

The fast syscall path clobbers 2 registers. Which is fine for a plain
...
system call, as long as the stub knows about it. However, it's bad
for sigreturn. Hence, use the old entry point for sigreturn. XXX

Remove fs and gs kludge.

c061e6bf8b
Enable the libc-provided signal trampoline. The old __sigaction14
...
entry point has been replaced by the new __sigaction14() which is a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.

8aa4d3caec
New __sigaction14() system call stub which registers the signal
...
trampoline, and the signal trampolines themselves.
NOTE: These are not yet enabled; they will be enabled after further
testing on more architectures.

Attempt to juggle the 2 seperarate status/mask bit sets for plain FP
...
and XMM to provide a consistent interface.

mov -> lea to access _map table.

Fix the EINVAL return path.

Add clone(2) implementation.

Use the syscall insn for system calls. Fix up some assembly to
...
remove either previously made errors, or to account for the
fact that syscall clobbers %ecx.

Revert previous: .S files are currently compiled with -traditional-cpp,
...
so __STDC__ is _not_ always defined.

__STDC__ is always defined on NetBSD.

2d8577fb83
Clean up some rampant code duplication wrt ieee number handling:
...
- Add alignment-safe double and float unions.
- Use the above for the __infinity and __nan constants on all
architectures that use the standard ieee754 representation of
those constants.
- Add a single copy of various ieee754 math functions (frexp, isinf,
isnan, ldexp and modf) that had numerous duplicates among the
arch-specific directories.
- Use the above functions on all architectures where the generic C
versions where used. Architectures that had local assembly
routines are untouched (for those functions only).

* Add WSYSCALL() to SYS.h, which creates a system call with an
...
internal name and a weak alias for the name.
* Add a WEAKASM syscall list, and process it.
* Make sysarch() have an internal name (_sysarch()).
