builtins.c (expand_builtin_setjmp): Delete.
* 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.
(tree_purge_dead_abnormal_call_edges): New function.
* tree-flow.h (tree_can_make_abnormal_goto): Declare.
(tree_purge_dead_abnormal_call_edges): Likewise.
(make_abnormal_goto_edges): Likewise.
* tree-inline.c (expand_call_inline): Simplify statement frobbing.
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.
(TARGET_UNWIND_TABLES_DEFAULT): Fix typo.
(DONT_USE_BUILTIN_SETJMP): Document it.
