This change
+ /* The N_FUN tag at the end of the function is a GNU extension,
+ which may be undesirable, and is unnecessary if we do not have
+ named sections. */
+ if (!use_gnu_debug_info_extensions
+ || NO_DBX_FUNCTION_END
+ || !targetm.have_named_sections
+ || DECL_IGNORED_P (decl))
+ return;
+
/* The Lscope label must be emitted even if we aren't doing anything
else; dbxout_block needs it. */
function_section (current_function_decl);
breaks -gstabs output for the very reason mentioned in the above
comment: dbxout_block will emit references to the Lscope label,
which is now undefined after your change ...
This causes gcc.dg/20041216-1.c to fail on s390.
Bye,
Ulrich
