Bah, I know what's wrong. The regression was caused by the following fix: 2004-11-22 John David Anglin <[EMAIL PROTECTED]> PR rtl-optimization/14838 * emit-rtl.c (get_first_nonnote_insn): Don't assume first insn is a note. (get_last_nonnote_insn): Don't assume last insn is a note. The above fix doesn't handle the case when the first/last insn is a sequence.
