There is one new testsuite failure. The test execute/20010605-2.c
seg faults in function baz. It looks as if the dp register has been
messed up. We are trying to pass a complex long double.
This is the last part of the baz call:
ldd 112(%r3),%r25
ldd 120(%r3),%r26
ldd 128(%r3),%r27 <== dp clobbered
ldd 136(%r3),%r28
ldo -16(%r30),%r29
b,l baz,%r2
nop
