Phobos2 in GDC is mostly a mirror of phobos hosted on dsource, with some GDC-specific changes here and there to emphasize on the different implementation details ie: most functions in core.stdc.math are all aliases to GCC builtins. A recent changeset made it possible for all GCC builtins to be CTFE'able now too, so as well as enum FOO = sqrt(2) now working (thus meeting an expected requirement), you can go a little more wild and throw other functions into the mix: enum BAR = lround(sqrt(2)). To note some of the bad things. Varargs are still a problem. And though InlineAsm is getting there, with most problems with codegen pretty much sorted, we still suck at outputting labels. As far as I'm aware, Phobos will be 64bit-friendly in time for the 2.051 roll out. But that is no good when other architectures still bare the brunt of things. :~) Regards
