Subject: 	* ch-exp.y (match_simple_name_string):  Don't lower-case here.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ad86f717998e7dfe321dd21bdd4d3a8005db9c4e;p=binutils-gdb.git

	* ch-exp.y (match_simple_name_string):  Don't lower-case here.
	* ch-exp.y (yylex):  First try name lookup using exact name
	typed by user;  if that fails, try lower-cased name.
