--- Comment #10 from Bernd Edlinger <bernd.edlinger at hotmail dot de> --- Hmm... I use this configuration: binutils-build: ../binutils-2.25/configure --prefix=/home/ed/gnu/m32c-rtems --target=m32c-rtems --disable-werror gcc-build: ../gcc-trunk/configure --prefix=/home/ed/gnu/m32c-rtems --target=m32c-rtems --enable-languages=c --disable-libssp Revision: 219900 with above patch. => build succeeds. But pr26255.c does not work. I have no idea how to fix that. Something wrong with addpsi3 constraints? I think there is another relatively simple issue with exception handling. What are your configure options?
