cfgcleanup.c (try_optimize_cfg): Replace call to delete_insn_chain by call to delete_insn.
2012-04-14 Tom de Vries <tom@codesourcery.com>
* cfgcleanup.c (try_optimize_cfg): Replace call to delete_insn_chain by
call to delete_insn. Remove code to reorder BASIC_BLOCK note and
DELETED_LABEL note, and move it to ...
* cfgrtl.c (delete_insn): ... here. Change return type to void.
(delete_insn_and_edges): Likewise.
(delete_insn_chain): Handle new return type of delete_insn. Delete
chain backwards rather than forwards.
* rtl.h (delete_insn, delete_insn_and_edges): Change return type to
void.
* cfglayout.c (fixup_reorder_chain): Delete unused label.
