[vms/committed]: Decode but ignore SPSC and EIDC sub-records.

Tristan Gingold gingold@adacore.com
Mon May 17 08:06:00 GMT 2010


Hi,

these both subrecords aren't frequent.  This patch will make them ignored while reading them; they are
also decoded and displayed by objdump -p.

Tristan.

2010-05-17  Tristan Gingold  <gingold@adacore.com>

	* vms-alpha.c: Include esgps.h and eidc.h.
	(_bfd_vms_slurp_egsd): Ignore SPSC and IDC sub-records.
	(evax_bfd_print_egsd_flags): New function, extracted from ...
	(evax_bfd_print_egsd): ..., calls evax_bfd_print_egsd_flags.  Handles
	EGSD__C_SPSC and EGSD__C_IDC.
