I've found a declaration for thread_data in thread.hxx, and the code to
clear it out in thread.cxx, along with the code to allocate slots in it. But
where is the code that actually accesses this array? I'm looking for the
source for Cyg_Thread::get_data, etc., but a global text search didn't turn
it up. Where is it?

packages/kernel/current/include/thread.inl:486:
inline CYG_ADDRWORD Cyg_Thread::get_data( Cyg_Thread::cyg_data_index index )
{
CYG_ASSERT( index < CYGNUM_KERNEL_THREADS_DATA_MAX,
"Per thread data index out of bounds");
CYG_ASSERT( (thread_data_map & (1<<index)) == 0,
"Unallocated index used");
return self()->thread_data[index];
}
