Subject: 	* stabsread.c (define_symbol):  If REG_STRUCT_HAS_ADDR is non-zero,
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=19406903ab6849e34361a3a0c2aabbf46cd029fc;p=binutils-gdb.git

	* stabsread.c (define_symbol):  If REG_STRUCT_HAS_ADDR is non-zero,
	follow typedefs before checking TYPE_CODE for structures and unions.
