Tree-SSA bootstrapped successfully on powerpc-ibm-aix5.1.0.0 with
mudflap deconfigured.
The segfault is occurring in emit-rtl.c:start_sequence(). AIX
allows dereferencing NULL, so cc1 actually makes more progress than it
would on other platforms, but the issue is that cfun->emit is NULL, so any
reference to "first_insn" or "last_insn" or "seq_stack" will fail.
The failure occurs while compiling the internal function
"_GLOBAL__I___mf_lc_mask", so the problem may be black magic CTOR
functionality that is not working with the AIX port.
