For hpux, is this simply because we don't link against libm?

No, we do link against libm. Same problem on Solaris 2.5.1 and 2.6: copysign is
in libm, but not copysignl.

No, only copysign and copysignf are available under hpux up to

Bother. Well, if I wanna use this for complex division, I'll have to come up
with some solution.

powerpc-darwin is complex as it uses IBM's 128bit format which does not have a simple sign bit any
more.

Well, yes and no. The msb *is* set iff the value is negative. So copysign
can be done by
xor. tmp, mswx, mswx
blt 0, 1f
fneg hi, hi
fneg lo, lo
1:
plus some additional data movement instructions.
Step 1, however, is getting IEEE quad precision stuff working...

Log message:
PR 19696
* optabs.c (expand_absneg_bit): Split out from expand_unop and
expand_abs_nojump and generalize. Use operand_subword and
emit_no_conflict_block. Support large modes.
(expand_abs_nojump): Use it. Use HONOR_SIGNED_ZEROS to fall
back to maximum.
(expand_unop): Likewise. Use HONOR_SIGNED_ZEROS to fall back
negation to subtraction.
(expand_copysign): Check that the format has signed zeros.
Use operand_subword and emit_no_conflict_block. Support large modes.
