Hello,
I have a basic-block and I want to get the last jump insn of it.
I use BB_END (bb) for that purpose.
The instruction I get is a NOTE_INSN_PROLOGUE_END which appears right
before the jump insn; and when doing NEXT_INSN for that note I get
the first insn of the next bb (code_label); which means the jump insn
was skipped...
Investigating this behavior showed that it occurs right after calling
cleanup_cfg () from cfg_layout_initialize (0) (which is been called
at the beginning of the new pass I'm working on -that is placed right
before pass_free_cfg)
It is not clear why BB_END (bb) did not return the jump insn as
expected...
Thanks,
Revital
