Heh, that it might even possible didn't even cross my mind. I was happy
enough to be able to exercise and inspect the before&after IR for most
of the new code paths in the patch in a GCC bootstrap, by placing
gcc_assert(gcc_stop_here_*||getenv("GCC_STOP_HERE_*")) at various
places, so that I could stop to inspect, skip them in a debugger or in a
full run to look at the compiler dumps. That alone took much longer
than I had to complete it :-(
