* expr.c (expand_builtin_setjmp): Accept two new arguments for
the labels to branch to on first and subsequent executions. Don't
play with __dummy. Rename `setjmp' insn to `builtin_setjmp_setup',
and provide it with the jmp_buf. Use only one of
`builtin_setjmp_receiver' or `nonlocal_goto_receiver',
and provide the former with the target label.
(expand_builtin) [BUILTIN_SETJMP]: Generate a label for use by setjmp.
(expand_builtin) [BUILTIN_LONGJMP]: Split out to ...
(expand_builtin_longjmp): ... here. Recognize a `builtin_longjmp'
insn to replace all of the normal nonlocal_goto code. Don't play
with __dummy. Correct arguments to nonlocal_goto.
* expr.h (expand_builtin_setjmp): Update prototype.
* except.c (start_dynamic_handler): When using builtin_setjmp,
generate more accurate flow information.
* alpha.md (nonlocal_goto_receiver_osf): Delete.
(nonlocal_goto_receiver_vms): Rename to nonlocal_goto_receiver.
(builtin_longjmp, builtin_setjmp_receiver): New.
* sparc.md (update_return): Disambiguate unspec number.
(nonlocal_goto): Rearrange arguments to match caller in except.c.
(builtin_setjmp_setup): Rename from setjmp. Match and ignore the
jmp_buf operand.
* mips.md (nonlocal_goto_receiver, builtin_setjmp_receiver): Remove.
(builtin_setjmp_setup*, builtin_longjmp): New.
