The testcase 6177.f seems to be miscompiled. The assembly output from this file
, at -O2, is
MAIN__:
save %sp, -112, %sp
st %g0, [%fp-16]
st %g0, [%fp-12]
call cabsf, 0
add %fp, -16, %o0
^^^^ This should be an ld.
sethi %hi(.LLC1), %g1
ld [%g1+%lo(.LLC1)], %f8
fcmpes %f0, %f8
nop
fbg .LL7
nop
jmp %i7+8
restore
.LL7:
call _gfortran_abort, 0
restore
nop
Changing the add above to an ld fixes the runtime failure.
I have no clue what is causing this.
