    • dwarf2out.c (output_call_frame_info): Use ASM_OUTPUT_ASCII to output ASCII by default. · 8d4e65a6 
              * dwarf2out.c (output_call_frame_info): Use ASM_OUTPUT_ASCII to
        output ASCII by default.  Only use ASM_OUTPUT_DWARF_STRING if
        flag_debug_asm is on.
        (output_die, output_pubnames, output_line_info): Likewise.

        * alias.c (init_alias_analysis): Add struct_value_incoming_rtx
        and static_chain_rtx into the potential base values array if
        they are registers.
Fixes bugs exposed by improved alias propagation code.

        * alias.c (new_reg_base_value): New array of potential base values.
        (unique_id): Now file scoped static.
        (find_base_value, case REG): Return the value in reg_base_value
        array for the REG if it exists.  Else, return the value from
        new_reg_base_value if copying args and REG is a hard register.
        (find_base_value, case PLUS): If either operand of the PLUS is
        a REG, try to get its base value.  Handle base + index and
        index + base.
        (record_set): Use new_reg_base_value instead of reg_base_value.
        (init_alias_analysis): Allocate space for new_reg_base_value too.
        Rework code to iterate over the insns propagating base value
        information until nothing changes.
Improve alias propagation significantly.

	* libgcc2.c (L_eh): Define __eh_pc.
	Replace __eh_type with generic pointer __eh_info.

Fri Oct 31 01:47:57 1997  Jason Merrill  <jason@yorick.cygnus.com>

	Support for nested exceptions.
	* tinfo2.cc (__is_pointer): New fn.
	* exception.cc (struct cp_eh_info): Define.
	(__cp_exception_info, __uncatch_exception): New fns.
	(__cp_push_exception, __cp_pop_exception): New fns.
	* except.c: Lose saved_throw_{type,value,cleanup,in_catch}.
 	Lose empty_fndecl.
	(init_exception_processing): Likewise.  __eh_pc is now external.
	(push_eh_info): New fn.
	(get_eh_{info,value,type,caught}): New fns.
	(push_eh_cleanup): Just call __cp_pop_exception.
	(expand_start_catch_block): Use push_eh_info.  Start the eh region
	sooner.
	(expand_end_eh_spec): Use push_eh_info.
	(expand_throw): Call __cp_push_exception to set up the exception info.
	Just pass the destructor or 0 as the cleanup.  Call __uncatch_exception
	when we rethrow.
	(expand_builtin_throw): Don't refer to empty_fndecl.
