Subject: Let '^' through the lexer
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f6f78318fca803c4907fb8d7f6ded8295f1947b1;p=binutils-gdb.git

Let '^' through the lexer

so that the (existing) code in parser and expression evaluator
actually get to see it and handle it as XOR.  Also adjust docu
to match what's there.
