Hi Geoff.
Could you or anyone else give me a hint as to why powerpc-eabispe is
not building after your patch of (See below for ICE while building
libstdc++):
http://gcc.gnu.org/ml/gcc-patches/2004-08/msg00022.html
I don't understand why this patch would cause an interaction with
FLOAT_REGS, though I do see more 'f's before 'm's now :-).
Perhaps I need a separate movdi_internal32 for SPE without the 'f'
constraints?
Thanks.
Aldy
