I forgot to update the changelog before, what I committed is:
* function.c (thread_prologue_and_epilogue_insns): Call
try_shrink_wrapping_separate. Compute the prologue_seq afterwards,
if it has possibly changed. Compute the split_prologue_seq and
epilogue_seq later, too.
* shrink-wrap.c: #include cfgbuild.h and insn-config.h.
(dump_components): New function.
(struct sw): New struct.
(SW): New function.
(init_separate_shrink_wrap): New function.
(fini_separate_shrink_wrap): New function.
(place_prologue_for_one_component): New function.
(spread_components): New function.
(disqualify_problematic_components): New function.
(emit_common_heads_for_components): New function.
(emit_common_tails_for_components): New function.
(insert_prologue_epilogue_for_components): New function.
(try_shrink_wrapping_separate): New function.
* shrink-wrap.h: Declare try_shrink_wrapping_separate.
