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.
PR target/656 also discusses the same problem.

State-Changed-Why:
Please identify all of the the specific failures -- both
those that appear with -mcpu=k6 and -mcpu=athlon. The former
are high-priority; the latter are not. Until we know
which failures are which, we cannot know when to downgrade
the report.
