--- Comment #4 from Iain Buclaw <ibuclaw at gdcproject dot org> --- (In reply to G. Steinmetz from comment #3) > > Commit was from 2018-01-14, i.e. over a year ago. > That makes me wonder, when will gdc be synchronized with dmd ? > The main dmd branch has been converted over to D as of v2.069. Whereas gdc is a continuation of the old C++ branch, with new features and bug fixes converted back to C++. Its equivalence is v2.076, with a few extra regression patches. Reason for staying with the C++ branch is so that gdc 9 release can be ported to as many platforms as possible. Then switch over to the D branch and be in lock-step with upstream dmd with regards to the latest implementation.
