Subject: [PATCH 09/10] testing for sym->op is unneeded for lookup_keyword()
Date: Sun, 9 Aug 2020 22:53:28 +0200 [thread overview]
Message-ID: <20200809205329.42811-10-luc.vanoostenryck@gmail.com> (raw)
In-Reply-To: <20200809205329.42811-1-luc.vanoostenryck@gmail.com>
All symbols returned by lookup_keyword() are of type SYM_KEYWORD,
because either:
1) it's in NS_KEYWORD (and all symbol in NS_KEYWORD are SYM_KEYWORD)
2) it's in NS_TYPEDEF and all *keywords* in NS_TYPEDEF are reserved
and so can't be user defined and so must be SYM_KEYWORD.
Thus, they all have a symbol_op associated to them and it's
unneeded to test it.
So, remove the unneeded test.
