Subject: [PATCH] perf tools: Kill off -Wcast-align
Date: Mon, 26 Oct 2009 14:40:01 +0900 [thread overview]
Message-ID: <20091026054000.GA13517@linux-sh.org> (raw)
The present use of -Wcast-align causes the build to blow up on SH due to
generating a "cast increases required alignment of target type" error on
each invocation of list_for_each_entry().
It seems that this was previously reported and killed off in the ia64
support patch, but nothing seems to have happened with that. Presumably
the same problem still remains there, too.
