I'm using bdwgc on iOS8 and later (including arm64). You need development
HEAD.

Hi Shiro,

RoboVM is a Java compiler for iOS.
They have a repo (github.com/robovm/bdwgc), a fork of official (
github.com/ivmai/bdwgc)

They have solved many issues using the collector on iOS (32, 64, and 32 on
64).
Like this one:
https://github.com/robovm/bdwgc/commit/330797462474976093d631058f784c843040e294

Does it mean that I will face all that issues on iOS using original bdwgc
code ?

Thanks,
-Kirill

Could be the case; my use was limited so it's very likely that I haven't
stepped
on to those nasty issues. Hopefully those fixes will get merged
into the upstream. The arm64 support is pre-release anyways, so YMMV...

Hello Kirill,
GC scans registers of other thread. This is a very target specific part - e.g. in case of Windows and iOS it uses context structure which contains all registers of the suspended thread.
I see, thanks
Unfortunatelly RoboVM have closed sources and we will not be able to see any further bugs fixed.
I have one more question about the GC,
What if one thread call gcalloc and have the result on a register for some time, how come the collecting thread (another one) can see this pointer ?
Thanks
