+
+ openVMS/Alpha: Provide filename and case_hack flags via
+ symbol table from gas.
+ Add case_hack code for symbol output from vax/vms.
+ * evax-alpha.c (evax_initialize): Remove filename handling,
+ filename is provided via symbol table.
+ (evax_get_symtab): Use local symbol count when setting up table.
+ * evax-egsd.c (_bfd_evax_slurp_egsd): Print correct name when
+ debugging.
+ (_bfd_evax_write_egsd): Skip file name symbol.
+ * evax-emh.c (get_vms_time_string): Local function now.
+ (_bfd_evax_write_emh): Extract source filename and case_hack flags
+ from symbol table.
+ * evax_write_etir (_bfd_evax_write_etir): Pass all symbol names
+ through _bfd_evax_case_hack_symbol.
+ * evax-misc.c (hash_string, _bfd_evax_case_hack_symbol): New
+ functions.
+ (_bfd_evax_basename): Removed.
+ (_bfd_get_vms_time_string): Moved to evax-emh.c.
+ * evax.h (evax_private_data_struct): Remove filename.
+ (flag_hash_long_names, flag_show_after_trunc,
+ flag_no_hash_mixed_case, vms_name_mapping): New flags for
+ vms_case_hack.
