I'm running my new optimization (LTO with one partition) on a SPEC17 test. I got the mysterious message "collect2: error: ld returned 1 exit status"
Now, first off, with my debugging on at full tilt and it's clear my optimization bailed out after analyzing the code without doing anything. Second, this is a canned test not modified by me or anybody else for that matter so, it's not a user error. Finally, reading various blogs it seems that old object files hanging around can make collect2 to go bonkers. Therefore, I used specmake to clean the build and it didn't help, not that this makes any sense with one partition. By the way, for those of you that get upset at the very notion of invoking LTO as one partition, it's actually not that bad. I can compiler gcc that way on a laptop in about 50 minuets using only 4.7% of my memory! Any ideas?? What's happening, how to diagnose what's happening, how to work around it, etc...
