- Uses rtems_global_user_env. Switch to POSIX Keys?
We can use POSIX keys, or do some optimization:
Since applications using a file system will very likely also enable the Newlib
re-entrancy we can re-use the __getreent() function for the file system
environment. In newlib_create_hook() we create a structure
struct S {
struct _reent reent;
rtems_user_env_t *env;
}
and assign it to thread->libc_reent;
The file system can then use
(struct S *) __getreent()
to get its file system environment. This approach allows a slightly faster
lock-up compared to POSIX keys and uses less memory.

/**

*/
SCORE_EXTERN void *rtems_ada_self;
This should be replaced with a function:
void *rtems_ada_self(void)
{
return _Thread_Get_executing()->rtems_ada_self;
}
