How to handle the -mieee SIGFPE problem in normal Debian packages
Please respect the Mail-Followup-To, as I'm not subscribed to this
list, and the discussion is relevant to #203722.
I'm currently looking at the following bug report
about a frequent SIGFPE on an alpha machine. I guess we all know the
cause of this bug, namely the non-standard alpha FPU semantics.
My question is about how to handle this bug:
IIUC, there are the following options:
1 Fix upstream FP calculations to not trigger SIGFPEs. this is
unfortunately not an option imho, because of lack of interest of
2 make all KDE programs install a SIG_IGN SIGFPE handler. This can be
done in kdelibs, and would be little work.
3 make upstream configure detect alpha and compile with -mieee if so.
4 wait for the gcc alpha patch to be included into gcc, which was
posted on this list recently.
What option would you suggest the Debian KDE packages take ? I don't
think there is any very FP-intensive code in the KDE packages, so
performance is not really that much of an issue.
