* builtins.c (expand_builtin_setjmp): Delete. (expand_builtin) <BUILT_IN_SETJMP>: Mark as unreachable. <BUILT_IN_SETJMP_SETUP>: New case. <BUILT_IN_SETJMP_DISPATCHER>: Likewise. <BUILT_IN_SETJMP_RECEIVER>: Likewise. * builtins.def (BUILT_IN_SETJMP_SETUP): New built-in stub. (BUILT_IN_SETJMP_DISPATCHER): Likewise. (BUILT_IN_SETJMP_RECEIVER): Likewise. * gimple-low.c (struct lower_data): New field calls_builtin_setjmp. (lower_function_body): Initialize it to false. If it is set to true at the end of the processing, emit the setjmp dispatcher. (lower_stmt) <CALL_EXPR>: Invoke lower_builtin_setjmp if the callee is __builtin_setjmp and set calls_builtin_setjmp to true as well. <MODIFY_EXPR>: Fall through to above case if there is a CALL_EXPR on the rhs of the assignment. (lower_builtin_setjmp): New function. * tree.c (build_common_builtin_nodes): Build BUILT_IN_SETJMP_SETUP, BUILT_IN_SETJMP_DISPATCHER and BUILT_IN_SETJMP_RECEIVER nodes. * tree-cfg.c (make_exit_edges) <CALL_EXPR>: Use specific predicate to detect calls that can go to non-local labels. Use specific helper to create the abnormal edges associated with them. <MODIFY_EXPR>: Likewise. (make_abnormal_goto_edges): New function extracted from... (make_goto_expr_edges): ...here. Call it for computed gotos. (simple_goto_p): Minor tweak. (tree_can_make_abnormal_goto): New predicate. (tree_redirect_edge_and_branch): Return zero on all abnormal edges.

Purge all dead abnormal edges if the call was in the last statement. * tree-optimize.c (has_abnormal_outgoing_edge_p): New predicate. (execute_fixup_cfg): If there are non-local labels in the function, scan the basic blocks and split them at calls that can go to non-local labels or add missing abnormal call edges. Write down the CFG in the dump file. (pass_fixup_cfg): Remove TODO_dump_func flag. * unwind-sjlj.c: Poison setjmp. * doc/install.texi (enable-sjlj-exceptions): Use more general wording. * doc/tm.texi (DWARF2_UNWIND_INFO): Likewise.
