MFC TLS fixes.

- Define LDBL_NBIT to be a mask indicating the position of the integer

2005-03-07T04:55:40Z

bit in a long double. For architectures that don't have such a bit, LDBL_NBIT is 0. This makes it possible to say `mantissa & ~LDBL_NBIT' in places that previously used an #ifdef to select the right expression. The optimizer should dispense with the extra arithmetic when LDBL_NBIT is 0 anyway. - Add an XXX comment for the big endian case.

Replace the ldexp() implementation in libc with a renamed copy of the

2005-01-22T06:03:40Z

scalbn() implementation from libm. (The two functions are defined to be identical, but ldexp() lives in libc for backwards compatibility.) The old ldexp() implementation... - was more complicated than this one - set errno instead of raising FP exceptions - got some corner cases wrong (e.g. ldexp(1.0, 2000) in round-to-zero mode) The new implementation lives in libc/gen instead of libc/$MACHINE_ARCH/gen, since we don't need N copies of a machine-independent file. The amd64 and i386 platforms retain their fast and correct MD implementations and override this one.

Eliminate gdtoa.mk and move its contents to ${MACHINE_ARCH}/Makefile.inc.

The purpose of having a separate file involved an abandoned scheme that would have kept contrib/gdtoa out of the include path for the rest of libc.

For variables that are only checked with defined(), don't provide

any fake value.

Unbreak memmove(). Return the dst argument. While here, fix the END

2004-09-04T00:23:15Z

macro to actually reference memmove, not memcpy.

Unbreak memcpy(). memcpy() is defined to return the dst argument.

2004-09-04T00:04:58Z

By using r8 instead of r14 to do the swap, we put the dst argument in the return register. Since bcopy() doesn't clobber r8, we don't have to do anything else. This fixes ports/textproc/aspell.

Make profiling actually work. The gcc compiler emits a call to the

2004-08-25T07:42:34Z

_mcount() stub when profiling is enabled. Emit this code sequence for assembly routines as welli (MCOUNT definition in . We do not pass the GOT entry however as the 4th argument, because it's not used. The _mcount() stub calls __mcount(), which does the actual work. Define _MCOUNT_DECL to define __mcount. We do not have an implementation of mcount(), so we define MCOUNT as empty, but have a weak alias to _mcount() in _mcount.S. Note that the _mcount() stub in the kernel is slightly different from the stub in userland. This is because we do not have to worry about nested routines in the kernel.

Add support for TLS in statically linked programs.
