Synopsis: IEEE_COMPLEX_DIVIDE defined on VAX target
State-Changed-From-To: feedback->closed
State-Changed-By: neroden
State-Changed-When: Wed Jan 1 10:32:02 2003
State-Changed-Why:
No feedback for six months, and the existing behavior is probably correct anyway.

State-Changed-When: Wed Jun 26 12:57:57 2002
State-Changed-Why:
IEEE_COMPLEX_DIVIDE causes the COMPLEX and DOUBLE COMPLEX
divide routines in libf2c to honor the *hardware* treatment
of x/0.0 with x != 0.0. This is the obvious choice when
running on IEEE-754 compliant hardware, but might be a
good choice on VAX too.
Please advice.
Note that complex division is generally expanded inline
by the Fortran front-end, unless -Os is given as a
command line option.

>Description:
libg2c/libF77/configure unconditionally emits the IEEE_COMPLEX_DIVIDE
define. Since the VAX doesn't have IEEE math, IEEE_COMPLEX_DIVIDE
should not be emitted.
>How-To-Repeat:
run libg2c/libF77/configure with a vax target.
>Fix:
Only emit IEEE_COMPLEX_DIVIDE if the target actually uses IEEE math.
