2003-06-18  Jakub Jelinek  <jakub@redhat.com>

	* dw2gencfi.c (EH_FRAME_ALIGNMENT): Define if not defined.
	(output_cie): Don't pad.
	(output_fde): Add align argument.  Pad to align if not 0.
	(cfi_finish): Set .eh_frame alignment to EH_FRAME_ALIGNMENT.
	Pad just last FDE to EH_FRAME_ALIGNMENT.

	* gas/cfi/cfi-i386.d: Regenerated.
	* gas/cfi/cfi-common-1.d: Regenerated.
	* gas/cfi/cfi-common-2.d: Regenerated.
