Hi Nathan,
Hi,
I had a need to add a new type of informative message on the modules
branch, with an option to enable it. The message is not a warning or an
error, but just 'hey, you asked if X happens. It happens just here'. This
is emitted as a note. I chose -fnote-$NAME for the option, but that wasn't
a very satisfactory solution.
I have learnt that clang has -R$NAME options for exactly this kind of
informative note. Presumably with -Rno-$NAME negation.
Presumably we could also use this for optimization notes -- 'I failed to
vectorize this loop because ...'
thoughts?
this would be very bad on Solaris: it's been using -R (the native form
of GNU ld -rpath) for ages; changing this now would cause much breakage.
oh gosh, I remember that :) thanks for the reminder!
