------- Comment #4 from steven at gcc dot gnu dot org 2006-07-25 22:52 -------
In the .104.expand dump we have:
(insn 10 9 11 3 (set (reg/f:SI 63)
(label_ref:SI 16)) -1 (nil)
(insn_list:REG_LABEL 16 (nil)))
and
;; Start of basic block 4, registers live: (nil)
(code_label 16 15 52 4 8 "" [1 uses])
But in the .105.sibling dump, we have already lost the label and in fact the
entire basic block 4. Apparently gcc decides that the block is unreachable...?
