Starting with r17-2606-g2c421a5cbe9d2b (Surya Kumari Jangala: rs6000:
Add support for Dense Math Facility (DMF) registers), building a cross
compiler from x86_64-linux to powerpc64-apple-darwin9 (and probably
also to powerpc-apple-darwin9 and powerpc-apple-darwin8) fails with
an ICE in in init_reg_sets, at reginfo.cc:193:

Please submit a full bug report, with preprocessed source (by using
-freport-bug).
Please include the complete backtrace with any bug report.
To test yourself, configure GCC with:
../src/configure --prefix=/home/mjambor/gcc/mine/inst
--enable-languages=c,c++ --enable-checking=yes --disable-bootstrap
--disable-multilib --enable-obsolete --target=powerpc64-apple-darwin9
and then make the compiler proper with:
make -j64 all-host CXXFLAGS="-O0 -g" CFLAGS="-O0 -g"
