gimple-ssa-isolate-paths.c (check_loadstore): New function.
* gimple-ssa-isolate-paths.c (check_loadstore): New function.
(insert_trap_and_remove_trailing_statements): New argument OP which
is the NULL pointer. Emit the trap after the load/store through
the NULL pointer. Simplify the RHS of a store through a NULL pointer
when trivial to do so.
(isolate_path): Corresponding changes.
(gimple_ssa_isolate_erroneous_path): Likewise.
* gcc.dg/tree-ssa/isolate-1.c: Update expected output.
* gcc.dg/tree-ssa/isolate-5.c: New test.
