a floating point instruction into a 6-bit register number for
double and quad arguments.
Make use of the new INSFPdq_RN macro where apporpriate; this
is required for correctly handling the "high" fp registers
(>= %f32).
Fix a number of bugs related to the handling of the high registers
which were caused by using __fpu_[gs]etreg() where __fpu_[gs]etreg64()
should be used (the former can only access the low, single-precision,
registers).

startup code rather than a static C++ object since c++ seems to be broken.
This doesn't seem to work for staticically linked program just yet, I'll
give that some more work when I get a chance.
except to generate spurious warnings about a system header <sys/param.h>
having some inline functions (the bswap family). This backs out the main
part of rev.1.5 (which was the only part left). The problem fixed by
rev.1.5 of the Makefile went away in rev.1.5 of ../common/crtbegin.c
when the references to do_ctors() and do_dtors() in the latter were moved
from inline asm to C code.
This leaves the problem that implementation details cause warnings.

on long double, which are not implemented in hardware on any UltraSPARC
chip that I know of. This just calls into the existing floating point
emulator, which is still needed to emulate other floating point operations
in certain conditions. Without this gcc has to generate the quad floating
point instructions directly, which sometimes causes internal compiler
errors.

using these to load long doubles, but they aren't implemented in hardware
on (at least) UltraSPARC I and II machines.
Emulate popc in the user trap handler as well.
Re-arrange slightly to make support functions more accessible.

- New length modifiers: hh, j, ll, t, z.
Still to do:
- %C, %S, %lc, %ls (wide character support)
- %a/%A (exact hex representation of floating-point numbers)
Removed old compatability equivalents:
- %D for %ld, %O for %lo, %X for %lx, %E and %F for %le & %lf (these
were buggy anyway, since they should have represented %Le & %Lf).
- %[unknown uppercase char] for %ld, %[unknown lowercase char] for %d
named by its argument and use ttyslot(3) instead to determine what slot to
use. The problem is that sshd(8) calls pam_open_session(3) before forking
the child (as it should), at which point it does not have a controlling
terminal. Also, ttyslot(3) is very crude as it assumes fd 0, 1 or 2 refers
to the controlling terminal, which is usually (but not always) the case.
Instead of using ttyslot(3) to determine the slot number, look up the
specified tty in /etc/ttys ourselves (this is what ttyslot(3) does anyway).

of this code. I very much doubt that "the FreeBSD way" really means "make
it as unreadable and unmaintable as possible", and I would like Makefile
style (which is not currently documented anywhere except in the minds of
bde and ru) to be discussed and agreed upon in the appropriate forum
before any further commits of this kind happen.
