I'm now fixed the epilogue part. In addition, I tried to track
down a close-brace line number to accompany early returns. I.e.
...
.stabn 68,0,8,$LM5
addl $2,1,$2
cmple $2,5,$1
bne $1,$L7
$LM6:
.stabn 68,0,18,$LM6
ret $31,($26),1
.align 4
$L3:
...
.stabn 68,0,14,$LM9
addl $2,1,$2
cmple $2,5,$1
bne $1,$L13
$LM10:
.stabn 68,0,18,$LM10
$LBE2:
ret $31,($26),1
.end foo
Note the 18 before both return instructions.
