--- Comment #4 from lucier at math dot purdue.edu --- Thanks for the explanation. Now that I understand the issue better, this whole approach---hijacking and hacking the PRE infrastructure to elide unnecessary reads and writes of a new, very special use, status register even when -fno-gcse is specified---seems unnecessarily heavy-handed and ill judged. But that's just me.
