2447 6206 d 16 h jermar /trunk/kernel/generic/src/main/ Split accidently joined lines.  
2446 6206 d 16 h jermar /trunk/kernel/generic/ More efficient and simpler task termination.

Based on the assumption, that after its creation, only the task itself can create more threads for itself,
the last thread with userspace context to execute thread_exit() will perform futex and IPC cleanup. When
the task has no threads, it is destroyed. Both the cleanup and destruction is controlled by reference
counting.

As for userspace threads, even though there could be a global garbage collector for joining threads, it is
much simpler if the uinit thread detaches itself before switching to userspace.

task_kill() is now an idempotent operation. It just instructs the threads within a task to exit.

Change in the name of a thread state: Undead -> JoinMe.
 
2445 6206 d 17 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2444 6207 d 8 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...
 
2443 6207 d 9 h jermar /trunk/ sscc -> suncc  
2442 6207 d 9 h jermar /trunk/ Add dummy option for Sun Studio C Compiler.
For each architecture, offer only compilers that support the target.
 
2441 6207 d 10 h decky /trunk/kernel/ fix ICC compilation  
2440 6207 d 10 h jermar /trunk/kernel/generic/ Fix the problem with sys_thread_create() by splitting the create and attach functionality of
thread_create(). Now it is possible to specify a flag that will cause thread_create() to only allocate and
initialize the thread structure. A call to thread_attach() will make the thread visible to the system.
This arrangement makes it easier to undo creation of a thread in case of a failure in sys_thread_create().
 
2439 6207 d 10 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2438 6207 d 10 h decky /trunk/ update for new compiler configuration scheme  
2437 6207 d 10 h decky /trunk/ experimental support for ICC
(the sources has to be modified to avoid ICC compiler warnings)
 
2436 6208 d 12 h jermar /trunk/ Fix two memory leaks.

In kernel, kernel_uarg structure needs to be deallocated when a thread
with userspace context is destroyed.

In userspace, the return value of the SYS_THREAD_CREATE must be checked
for error conditions and in case of error, uarg and stack must be freed
up.
