Subject: This fixes ! to work as documented in a memory region attribute list.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=aa8804e46ee31cc1d2e00f57467c8e5a4a84a273;p=binutils-gdb.git

This fixes ! to work as documented in a memory region attribute list.
	From Thomas Zenker <thz@lennartz-electronic.de>:
	* ldgram.y (attributes_opt): Use attributes_list instead of NAME.
	(attributes_list, attributes_string): New nonterminals.
	* ldlang.c (lang_set_flags): Add invert parameter.  Don't handle
	'!'.
	* ldlang.c (lang_set_flags): Update declaration.
