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 :-( -- Alexandre Oliva, freedom fighter he/him https://FSFLA.org/blogs/lxo Be the change, be Free!
