X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9e4f353ca9d4f4ae70ce76ae704e5686d47e2f63;p=binutils-gdb.git

Factor out struct and union printing code from c_val_print

gdb/ChangeLog:

	* c-valprint.c (c_val_print): Factor out struct and union
	printing code to ...
	(c_val_print_struct): ... this new function ...
	(c_val_print_union): ... and this new function.
