2455 6204 d 9 h jermar /trunk/kernel/ Some non-C files (e.g. .S and linker scripts) must be still "compiled" with gcc and GCC_CFLAGS.  
2454 6204 d 9 h jermar /trunk/kernel/ A bit of infrastructure for building with different compilers.
CFLAGS split into GCC_CFLAGS and SUNCC_CFLAGS.
As of now, there are no separate ICC_CFLAGS, but can be easily added.
 
2453 6204 d 15 h jermar /trunk/kernel/ More suncc fixes.
- remove more empty declarations
- add options to turn errors on empty structs into warnings and options to
silence these warnings
 
2452 6204 d 17 h jermar /trunk/kernel/ More suncc fixes.
- Removed extra semicolons after function declaration.
- Sun Studio recognizes only C99 __func__ and no gcc-specific __FUNCTION__.
In this case, a simple -D option can fix the problem.
 
2451 6205 d 11 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2450 6206 d 13 h mencl /branches/rcu/kernel/ Repaired avl and extavl tree timeout unregister and delete_min. These
faults caused problems with initializing cpus and they appeared only in
multi processor systems.
 
2449 6207 d 22 h decky /trunk/uspace/rd/ remove unnecessary includes  
2448 6208 d 14 h jermar /branches/arm/kernel/arch/arm32/src/cpu/ Start the CPU identification string with cpu[0-9].  
2447 6208 d 15 h jermar /trunk/kernel/generic/src/main/ Split accidently joined lines.  
2446 6208 d 15 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 6208 d 17 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2444 6209 d 7 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...
 
2443 6209 d 8 h jermar /trunk/ sscc -> suncc  
2442 6209 d 9 h jermar /trunk/ Add dummy option for Sun Studio C Compiler.
For each architecture, offer only compilers that support the target.
 
2441 6209 d 9 h decky /trunk/kernel/ fix ICC compilation  
2440 6209 d 9 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 6209 d 9 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2438 6209 d 10 h decky /trunk/ update for new compiler configuration scheme  
2437 6209 d 10 h decky /trunk/ experimental support for ICC
(the sources has to be modified to avoid ICC compiler warnings)
 
2436 6210 d 11 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.
