--- Comment #58 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- With the latest build-many-glibcs.py build <https://sourceware.org/ml/libc-testresults/2017-q4/msg00468.html>, using GCC trunk r255614, ia64 fails with an ICE building libgcc, m68k fails with an ICE building glibc, sh fails with prev_nonnote_insn_bb and next_nonnote_insn_bb undeclared compiling insn-emit.c. The other compilations pass (though it's always possible ICEs will appear in the glibcs build, building additional glibc variants and the glibc testsuite).
