Subject: objcopy of archives tidy
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c1eb3cd205921fb7af668f2032ab2c7142c4f24c;p=binutils-gdb.git

objcopy of archives tidy

This makes sure the input element bfd is closed before exiting the
loop copying elements.

	* objcopy.c (copy_archive): Rename output_bfd to output_element.
	Localise last_element.  Close this_element in more error cases.
