2460 6186 d 15 h jermar /trunk/kernel/ Better infrastructure for building with different compilers.
Separate ICC_CFLAGS added, SUNCC_CFLAGS extended.
 
2459 6186 d 18 h jermar /trunk/kernel/arch/ Fix a bug in ia32 and ia32xen Sun Studio builds.
In arch Makefile.inc, SUNCC_CFLAGS can only be appended via the += operator.
 
2458 6186 d 18 h jermar /trunk/kernel/arch/mips32/ Fix mips32 build script.
Replace CFLAGS with GCC_CFLAGS.
 
2457 6186 d 18 h jermar /trunk/kernel/arch/ia32xen/src/smp/ Fix ia32xen so that it can be built.  
2455 6187 d 13 h jermar /trunk/kernel/ Some non-C files (e.g. .S and linker scripts) must be still "compiled" with gcc and GCC_CFLAGS.  
2454 6187 d 14 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 6187 d 19 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 6187 d 21 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 6188 d 15 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2449 6191 d 2 h decky /trunk/uspace/rd/ remove unnecessary includes  
2447 6191 d 19 h jermar /trunk/kernel/generic/src/main/ Split accidently joined lines.  
2446 6191 d 19 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 6191 d 21 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2444 6192 d 11 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...
 
2443 6192 d 12 h jermar /trunk/ sscc -> suncc  
2442 6192 d 13 h jermar /trunk/ Add dummy option for Sun Studio C Compiler.
For each architecture, offer only compilers that support the target.
 
2441 6192 d 13 h decky /trunk/kernel/ fix ICC compilation  
2440 6192 d 14 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 6192 d 14 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2438 6192 d 14 h decky /trunk/ update for new compiler configuration scheme
