https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66854 --- Comment #4 from Sebastian Huber sebastian.hu...@embedded-brains.de --- (In reply to Michael Meissner from comment #3) Created attachment 35978 [details] Proposed patch to fix the problem I believe this patch fixes the problem. I was able to build libgcc with this patch installed. I could not complete a full RTEMS build (I suspect I am missing some parts of the software). Thanks for the quick fix. With your patch I can build without errors. To build the powerpc-rtems target you need a link to the latest Newlib in your GCC directory, e.g. newlib - ../newlib-git/newlib. I used the following configure options: ../gcc-git/configure --prefix=/opt/rtems-4.11 --target=powerpc-rtems4.11 --verbose --with-gnu-as --with-gnu-ld --with-newlib --disable-libstdcxx-pch --disable-nls --disable-lto --disable-plugin --without-included-gettext --enable-version-specific-runtime-libs --enable-threads --enable-newlib-io-c99-formats --enable-libgomp --enable-languages=c,c++

Are the RTEMS include files and libraries available on the internet so that I can try to build a cross compiler to debug the problem?
