Making slow progress...
I now have libstdc++ compiled as "standalone" I am down to "free",
"malloc", "abort", and "_restf4". free and malloc I can hook up to
net_free and net_malloc. abort I can hook up to panic. Its the
_restf14 that gets me.
It is pulled in from unwind_dw2.o of libgcc_eh.a. The IBM pubs tells
me its part of the floating point linkage convention.
So, it sounds to me like I need to recompile libgcc_eh.a with the
soft-float option.
Can someone help me do this with minimal stress?
Thanks,
Perry

GCC will generate uses of floating point registers from source
code that only describes integer computations. GCC 4.1 will do so
less
often, but nothing has changed to prevent it. One can use the soft-
float
option, but this confuses people who want to use floating point
registers
in code that does describe floating point computations.
