It's required for LDC's custom TLS emulation for Android, see 1st point in https://wiki.dlang.org/Build_D_for_Android#Directions_for_future_work. lld supports custom linker scripts AFAIK, so that should get it to work as well (putting the two sections adjacent to each other). There's a runtime check making sure the executable has been linked as expected.

I got it working, kind of. I just needed to use a different ndk version. There's a lot of problems with the NDK, the latest one doesn't appear to have the bfd linker anymore. Does anyone know why the bfd linker is needed and why the gold linker doesn't work for the emulated TLS?

If you're linking manually, make sure that `-ldruntime-ldc` comes *after* `-lphobos2-ldc`, and that your druntime lib has been compiled for the appropriate arch. CPU_COUNT is a druntime symbol too. Yes I tried changing the order, it seems like I am getting all unresolved symbols for D. Including _d_assert, but only when I use the --no-undefined flag. I have no idea why it is spitting out so many unresolved references.

There should be linker errors I'm expecting but if I take out that flag then I don't get any...
