The gcc 6.3-1 compiler has been out for a while. Is there a target date for it's arrival in Tumbleweed?

I just want to clarify one point

If I create an object file with Tumbleweed's gcc 6.2 compiler, and that from another distribution, the object modules are identical in size.
a Diff on the modules just shows the difference as "date compiled".

I ran with gcc -v to produce reams of logging info. It generates many many lines, I decided to just compile my programs on another system and bring them over to tumbleweed.
