re PR tree-optimization/60003 (wrong code with __builtin_setjmp/__builtin_longjmp and inlining)
PR tree-optimization/60003
* gimple-low.c (lower_builtin_setjmp): Set cfun->has_nonlocal_label.
* profile.c (branch_prob): Use gimple_call_builtin_p
to check for BUILT_IN_SETJMP_RECEIVER.
* tree-inline.c (copy_bb): Call notice_special_calls.
* gcc.c-torture/execute/pr60003.c: New test.
