At least this patch:

http://gcc.gnu.org/ml/gcc-patches/2010-06/msg02056.html

causes ICEs with powerpc-eabispe when compiling -msoft-float's libgcc:

../../.././gcc/dp-bit.c: In function '_fpadd_parts':
../../.././gcc/dp-bit.c:731:1: internal compiler error: in check_allocation, at ira.c:1629
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

I am way out of my depth debugging this code; I tried loading everything
into gdb to provide a little more useful information, but of course the
compilation succeeds when cc1 is being run under gdb. :(
