* [Bug c/13317] New: Combination of options produces broken program on UltraSparc

I get a "Bus error" when compiling one test with

  gcc -lrt -std=gnu99 -O1 -o treebug \
    -mcpu=ultrasparc \
    -fcse-follow-jumps \
    -fgcse \
    -fschedule-insns \
    -finline-functions \
    -fnew-ra \
    treebench.c

Compiled without any one of those options, and the resulting program runs
without exception. I suspect the problem is predicated on -fnew-ra, given the
number of problems with that option I've had on Intel processors. On Intel,
though, -fnew-ra produced an collection of different compiler errors, while on
the SPARC, it produces a broken program.

I have not been able to reduce the size of the test program, but my time has
been somewhat limited. I'm posting the full program with this report, and will
try to reduce it in the coming days.
