NAME
fptrap - floating point interpreter
SYNOPSIS
sys signal; 4; fptrap
DESCRIPTION
Fptrap is a simulator of the 11/45 FP11-B floating point
unit. It works by intercepting illegal instruction traps
and decoding and executing the floating point operation
codes.
FILES
In systems with real floating point, there is a fake routine
in /lib/liba.a with this name; when simulation is desired,
the real version should be put in liba.a
DIAGNOSTICS
A break point trap is given when a real illegal instruction
trap occurs.
SEE ALSO
signal (II), cc (I) (`-f' option)
BUGS
Rounding mode is not interpreted. It's slow.
