Running with gdb, it looks like the problem comes from the
ppc_closure.S file of the libffi/src/powerpc directory, at line 32 :
Maybe something like:
#ifndef _SOFT_FLOAT
stfd %f1, 48(%r1)
#endif
but then, you might have to have something like:
#define CPP_SPEC \
"%{msoft-float: -D_SOFT_FLOAT} \
(picked at random from lynx.h) in the .h file for your port.
:-) But I'm sure there would be more work to do.
FWIW the backend already does this in rs6000-c.c :)
Yeah, I thought it was in there someplace, but my grep
FWIW a few years ago, we tried to make sure all the RTEMS targets
defined _SOFT_FLOAT when msoft-float was specified. Hopefully
that is still around and consistent. RTEMS is built multilib so we
need a conditional to let us know which multilib it is so we can do
the right thing. I imagine newlib depends on them too in many places.
