Subject: In PowerPC as, allow a lonely lo16 without hi16 or ha16.
X-Git-Url: https://git.ndcode.org/public/gitweb.cgi?a=commitdiff_plain;h=a9d305f3d84c4ae7dfac39abf0d629319b388078;p=ack.git

In PowerPC as, allow a lonely lo16 without hi16 or ha16.

The intent is to assemble code like

    lis r3, ha16[_sym]
    lwz r4, lo16[_sym](r3)
    addi r4, r4, 1
    stw r4, lo16[_sym](r3)
