We've started migrating to gcc 2.7.0 having been happily running 2.6.3 for quite a while. We run our gcc on pc's running linux installed from slackware. The motivation for the move is to start exploiting the presumed benefits of ELF format. HOWEVER, with the new gcc there appears to have been a precipitous drop in performance. A compilation which formerly took 10 seconds now takes 5 minutes. Watching the system using top, the time is spent in as . The cpu is virtually idle, there is no paging, there is plenty of swap space and memory (64 M machine). I've rebuilt the kernel. Actually the 5 minute number is from after rebuilding the kernel. The performance was initially even worse. I've rebuilt the compiler and binutils all to no effect. Has anyone experienced a comparable problem and solved it? Is this a gcc problem or a linux problem? Both perhaps? -m
