The following are the failures with 3.0: loop-2b.c -mcpu=k6 -O3 -fomit-frame-pointer loop-2b.c -mcpu=k6 -O3 -fomit-frame-pointer -funroll-loops loop-2b.c -mcpu=k6 -O3 -fomit-frame-pointer -funroll-all-loops -finline-functions loop-2b.c -mcpu=k6 -O3 -g loop-2b.c -mcpu=k6 -Os loop-2b.c -mcpu=k6 -O2 loop-2b.c -mcpu=athlon -O3 -fomit-frame-pointer loop-2b.c -mcpu=athlon -O3 -fomit-frame-pointer -funroll-loops loop-2b.c -mcpu=athlon -O3 -fomit-frame-pointer -funroll-all-loops -finline-functions loop-2b.c -mcpu=athlon -O3 -g loop-2b.c -mcpu=athlon -Os loop-2b.c -mcpu=athlon -O2 loop-2e.c -mcpu=athlon -O3 -fomit-frame-pointer loop-2e.c -mcpu=athlon -O3 -g loop-2e.c -mcpu=athlon -Os loop-2e.c -mcpu=athlon -O2 loop-3c.c -mcpu=k6 -O3 -fomit-frame-pointer loop-3c.c -mcpu=k6 -O3 -fomit-frame-pointer -funroll-loops loop-3c.c -mcpu=k6 -O3 -fomit-frame-pointer -funroll-all-loops -finline-functions loop-3c.c -mcpu=k6 -O3 -g loop-3c.c -mcpu=k6 -Os loop-3c.c -mcpu=k6 -O2 loop-3c.c -mcpu=athlon -O3 -fomit-frame-pointer loop-3c.c -mcpu=athlon -O3 -fomit-frame-pointer -funroll-loops loop-3c.c -mcpu=athlon -O3 -fomit-frame-pointer -funroll-all-loops -finline-functions loop-3c.c -mcpu=athlon -O3 -g loop-3c.c -mcpu=athlon -Os loop-3c.c -mcpu=athlon -O2 Of these, the following are regressions: loop-2b.c -mcpu=k6 -Os loop-3c.c -mcpu=k6 -O3 -fomit-frame-pointer loop-3c.c -mcpu=k6 -O3 -fomit-frame-pointer -funroll-loops loop-3c.c -mcpu=k6 -O3 -fomit-frame-pointer -funroll-all-loops -finline-functions loop-3c.c -mcpu=k6 -O3 -g loop-3c.c -mcpu=k6 -Os loop-3c.c -mcpu=k6 -O2 Two testcases appear to hang: loop-3c.c -mcpu=k6 -O3 -fomit-frame-pointer -funroll-loops loop-3c.c -mcpu=k6 -O3 -fomit-frame-pointer -funroll-all-loops -finline-functions The rest of the failures abort quickly.
