[vms/committed] Do not create anymore dummy sections


Hi,

there was code in vms-alpha.c to generate dummy sections in object files in case of non-consecutive
sections index.  Although I never saw such sections, this code can be removed by using target_index instead.

Committed.

Tristan.

2010-06-25  Tristan Gingold  <gingold@adacore.com>

	* vms-alpha.c (_bfd_vms_write_egsd): Set target_index field of
	sections.  Mark .vmsdebug section as SEC_DEBUGGING.  Do not create
	dummy psect anymore.  Adjust.
	(_bfd_vms_write_eeom): Adjust (use target_index instead of index)
	(_bfd_vms_write_etir): Ditto.
	(start_etir_or_etbt_record): Test for SEC_DEBUGGING instead of
	section name.  Adjust.
