Subject: [PATCH] gas/config/ 	* tc-xgate.h: Defined tc_frob_symbol. 	*
 tc-xgate.c (xgate_frob_symbol): Wrote new function to mark 	  symbols as
 being XGATE by setting st_target_internal value.

bfd/
	* elf32-xgate.c (elf32_xgate_add_symbol_hook): Added a temp patch
	  that forces st_target_internal to equal 1, since tc_frob_symbol
	  seems to need adjusting.
