Another testcase from open-office this time, on i?86-linux only. $> time g++ -c -g -Os -fomit-frame-pointer analysis.ii real 103m46.642s user 96m21.093s sys 0m1.196s $> time g++ -c -g -Os analysis.ii real 0m19.345s user 0m19.177s sys 0m0.168s $> time g++ -c -Os -fomit-frame-pointer analysis.ii real 0m3.747s user 0m3.640s sys 0m0.104s numbers above are from the 4.5 branch rev. 159866. trunk is also very slow, but the compile didn't yet finish. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41371
