* tree.h (BUILT_IN_CALLER_RETURN_ADDRESS): Unused. Kill.
(BUILT_IN_FP, BUILT_IN_SP, BUILT_IN_SET_RETURN_ADDR_REG): Kill.
(BUILT_IN_EH_STUB_OLD, BUILT_IN_EH_STUB, BUILT_IN_SET_EH_REGS): Kill.
(BUILT_IN_EH_RETURN, BUILT_IN_DWARF_CFA): New.
* c-decl.c (init_decl_processing): Update accordingly.
* expr.c (expand_builtin): Likewise.
* cp/decl.c (init_decl_processing): Likewise.
* rtl.h (global_rtl): Add cfa entry.
(virtual_cfa_rtx, VIRTUAL_CFA_REGNUM): New.
(LAST_VIRTUAL_REGISTER): Update.
* emit-rtl.c (global_rtl): Add cfa entry.
(init_emit): Initialize it.
* function.c (cfa_offset): New.
(instantiate_virtual_regs): Initialize it.
(instantiate_virtual_regs_1): Instantiate virtual_cfa_rtx.
(expand_function_end): Call expand_eh_return.
* tm.texi (ARG_POINTER_CFA_OFFSET): New.
* except.c (current_function_eh_stub_label): Kill.
(current_function_eh_old_stub_label): Likwise; update all references.
(expand_builtin_set_return_addr_reg): Kill.
(expand_builtin_eh_stub_old, expand_builtin_eh_stub): Kill.
(expand_builtin_set_eh_regs): Kill.
(eh_regs): Produce a third reg for the actual handler address.
(eh_return_context, eh_return_stack_adjust): New.
(eh_return_handler, eh_return_stub_label): New.
(init_eh_for_function): Initialize them.
(expand_builtin_eh_return, expand_eh_return): New.

* function.h (struct function): Kill stub label elements.
* libgcc2.c (in_reg_window): For REG_SAVED_REG, check that the
register number is one that would be in the previous window.
Provide a dummy definition for non-windowed targets.
(get_reg_addr): New function.
(get_reg, put_reg, copy_reg): Use it.
(__throw): Rely on in_reg_window, not INCOMING_REGNO. Kill stub
generating code and use __builtin_eh_return. Use __builtin_dwarf_cfa.
* alpha.c (alpha_eh_epilogue_sp_ofs): New.
(alpha_init_expanders): Initialize it.
(alpha_expand_epilogue): Use it.
