I ran into the problem of that newlib did not implement most of the
C99 math functions or macros. I ran into the problem that FP_ILOGB0
was not defined and I was wondering if anyone is working on adding any
of the C99 math functions to newlib?
Also is there a bug system for newlib because it would be great to file bugs about the problems I ran into.
Thanks, Andrew Pinski
Well, newlib's printf() does not support "%a"/"%A" which are required by C99, so my observation of the C99 support at least is "spotty at best".
Meanwhile, I'll wait anxiously to see you get any more attention from the 'official' folks than I've gotten so far.
Now that we know you're here, do you know if anyone is working on adding C99-conformance to newlib? ;-)
I don't think that newlib has a roadmap. Any changes would come from either contributions or talking very nicely to Jeff. Since newlib isn't Jeff's full-time job, I would imagine that adding major new functionality won't be high on his to-do list.
This seems as good a place to jump in as any now that I am back from my vacation.
2. There is no roadmap in place to be fully C99 or POSIX-compliant. Newlib is still targetted at embedded systems with a minimal set of syscalls. That said, I have no problem with adding C99 and POSIX features to newlib that are helpful in getting more applications to run. I recently added hex floating-point support to strtod for example.
