[gnu.utils.bug] M68881 probs/gcc

lethin@WHEATIES.AI.MIT.EDU (Richard Lethin) (10/25/88)

More on this bug:

gcc has a bug in that it compiles assuming that a M68881 floating
point coprocessor is available, when I compile my program on
cream-of-wheat.  I cannot run my program on kaboom (a 3/50).
Additionally, I cannot run gcc itself on a 3/50 because it's compiled
assuming a M68881 fp coprocessor!

The default should be the equivalent of the Sun cc -fsoft switch or a
switch sould be provided to get -fsoft behavior and a manual page
should be made available to document it.

** This seems to be a recent change in behavior; old versions of the
program that I built do run on the 3/50.  It might be that the
libraries have been compiled assuming the 68881.
