re PR rtl-optimization/21803 ([ia64] gcc produces really odd predicated code)
gcc/
PR target/21803
* ifcvt.c (cond_exec_process_if_block): Look for identical sequences
at the start and end of the then/else blocks, and omit them from the
conversion.
* cfgcleanup.c (flow_find_cross_jump): No longer static. Remove MODE
argument; all callers changed. Pass zero to old_insns_match_p instead.
(flow_find_head_matching_sequence): New function.
(old_insns_match_p): Check REG_EH_REGION notes for calls.
* basic-block.h (flow_find_cross_jump,
flow_find_head_matching_sequence): Declare functions.
gcc/testsuite/
PR target/21803
* gcc.target/arm/pr42496.c: New test.
