Subject: [PATCH] parisc: prefer _THIS_IP_ and _RET_IP_ statement expressions
Date: Wed,  1 Aug 2018 11:22:56 -0700	[thread overview]
Message-ID: <20180801182258.17834-1-ndesaulniers@google.com> (raw)

As part of the effort to reduce the code duplication between _THIS_IP_
and current_text_addr(), let's consolidate callers of
current_text_addr() to use _THIS_IP_.
