Subject: [PATCH] [SFrame-V3] sframe: gas: libsframe: remove padding field from
 FDE

Remove the unused sfde_func_padding2 member from the
sframe_func_desc_entry_v3 structure.

A later patch in this series reorganizes the members of the FDE
structure in a way explicit padding is no longer necessary to keep
natural alignment.  So remove the explicit padding now.

include/
	* sframe.h: Remove sfde_func_padding2 from
	sframe_func_desc_entry_v3.
gas/
	* gen-sframe.c (output_sframe_funcdesc): Stop writing
	sfde_func_padding2.
libsframe/
	* sframe.c (sframe_encoder_write_fde): Stop writing
	sfde_func_padding2.
	* testsuite/libsframe.decode/DATA2: Regenerate binary test data.
