Unless someone tells me to be quiet, I'm gonna post what I find out so that someone who like, ya know, knows what they are doing can provide some tips. This is usually a problem in the machine description ... right? I built the compiler with -O1. Why can't gdb find the source? What did I mess up? Thanks!
