--- Comment #3 from Frederic Riss <frederic.riss at gmail dot com> 2011-03-28 09:58:50 UTC --- In bug #34678 I thought you were agreeing with Joseph that -frounding-math had a more general meaning than the one you are expressing here, but I get your point that a more general solution should be implemented. Regarding the validity of the testcase, I took glibc's implementation of fesetround that I inlined. I did that because I saw that /usr/include/fenv.h has provisions for including inline versions of the fenv routines, although it's not the case yet for x86. So I guess it's possible that someday you get exactly that situation even though people are using the standard routines to switch rounding mode. In fact my private port does exactly this. Can you think of other places than CSE that would exhibit these issues? Unfortunately, I have to put some band-aids into place for our numerical analysts to be able to do their jobs.
