Subject: 	* libaout.h (struct aoutdata): Add line_buf field.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f1c6dd5d163360c9dadd850ebe0069e1774cb8c9;p=binutils-gdb.git

	* libaout.h (struct aoutdata): Add line_buf field.
	* aoutx.h (NAME(aout,find_nearest_line)): Remove statics buffer
	and filename_buffer.  Instead, use a malloc buffer stored in the
	new line_buf field.  Remove length restrictions.
