Subject: 	* config/obj-som.h (obj_set_symbol_type): Define a hook so GAS
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e75acd689b12126432ca1ef8659d388475f12473;p=binutils-gdb.git

	* config/obj-som.h (obj_set_symbol_type): Define a hook so GAS
	can properly set all the SOM symbol types.
	* config/tc-hppa.c (pa_symbol_type): New enum to represent the
	symbol types which can be set from an IMPORT/EXPORT statement.
	(pa_export_args): Set the pa_symbol_type type based on arguments.
	If defined, call obj_set_symbol_type to pass this information on
	to the BFD backend.
