> It's out of scope for this patch, but there is definitely a delta here between how we emit thread-local (to .tbss) and non-thread local uninitialized data (i.e. to regular data section instead of bss) beyond just the thread-local part. Not sure if that's something we should address.
As a follow on, as discussed offline, using common for uninitialized data may have linkage considerations. We should consider if this applies to `.tbss` data as well before using `.comm` directives.
