With planned removal of Thread:: exceptions, we need to consider that a 'Thread' object may exist without a valid 'Stack' and therefore without a valid 'Native_thread', which is hosted as part of the 'Stack'. This patch reworks the code that accesses the 'Native_thread' to use the new 'Thread::with_native_thread' interface. Within the local scope, the native thread is referred to as 'nt'. The _init_platform_thread and _deinit_platform_thread() have been replaced by _init_native_thread and _deinit_native_thread, which take a 'Stack &' as argument. As a safety caution, 'Native_thread' objects can no longer be copied. Issue #5245

|
|
* framework. However, on Fiasco.OC, we make the type publicly available to
|
|
* expose the low-level thread-specific capability selectors to L4Linux.
