christos | Create a new header lwp_private.h to contain _lwp_getprivate_fast,
_lwp_gettcb_fast, _lwp_settcb and remove them from mcontext.h, so that:
1. we don't need special hacks to hide them
2. we can include <lwp.h> where needed to get the necessary prototypes
without redefining them locally.

kamil | Introduce _UC_MACHINE_FP() as a macro
_UC_MACHINE_FP() is a helper macro to extract from mcontext a frame pointer.
Don't rely on this interface as a compiler might strip frame pointer or
optimize it making this interface unreliable.
For hppa assume a small frame context, for larger frames FP might be located
in a different register (4 instead of 3).
For ia64 there is no strict frame pointer, and registers might rotate.
Reuse 79 following:
./gcc/config/ia64/ia64.h:#define HARD_FRAME_POINTER_REGNUM LOC_REG (79)
Once ia64 will mature, this should be revisited.
A macro can encapsulate a real function for extracting Frame Pointer on
more complex CPUs / ABIs.
For the remaining CPUs, reuse standard register as defined in appropriate ABI.
The direct users of this macro are LLVM and GCC with Sanitizers.
Proposed on tech-userlevel@.

joerg | Allow storing and receiving the LWP private pointer via ucontext_t
on all platforms except VAX and IA64. Add fast access via register for
AMD64, i386 and SH3 ports. Use this fast access in libpthread to replace
the stack based pthread_self(). Implement skeleton support for Alpha,
HPPA, PowerPC, SPARC and SPARC64, but leave it disabled.
Ports that support this feature provide __HAVE____LWP_GETPRIVATE_FAST in
machine/types.h and a corresponding __lwp_getprivate_fast in
machine/mcontext.h.
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

- Introduce _UC_MACHINE_FP(). _UC_MACHINE_FP() is a helper
macro to extract from mcontext a frame pointer.
- Add new tests in lib/libc/sys/t_ucontext:
* ucontext_sp (testing _UC_MACHINE_SP)
* ucontext_fp (testing _UC_MACHINE_FP)
* ucontext_pc (testing _UC_MACHINE_PC)
* ucontext_intrv (testing _UC_MACHINE_INTRV)
Add a dummy implementation of _UC_MACHINE_INTRV() for ia64.
Implement _UC_MACHINE_INTRV() for hppa.
Make the t_ucontext.c test more portable.
We now have _UC_MACHINE_FP.

Improve _UC_MACHINE_FP() for SPARC/SPARC64
Introduce a static inline function _uc_machine_fp() that contains improved
caluclation of a frame pointer.
Algorithm:
uptr *stk_ptr;
# if defined (__arch64__)
stk_ptr = (uptr *) (*sp + 2047);
# else
stk_ptr = (uptr *) *sp;
# endif
*bp = stk_ptr[15];
Noted by <mrg>
--
Make _UC_MACHINE_FP() compile again and fix it so that it does not add
the offset twice.
--
fix _UC_MACHINE32_FP() -- use 32 bit pointer value so that [15] is
the right offset. do this by using __greg32_t, which is only in
the sparc64 version, and these are only useful there, so move them.
--
Add new tests in lib/libc/sys/t_ucontext
New tests:
- ucontext_sp
- ucontext_fp
- ucontext_pc
- ucontext_intrv
They test respectively:
- _UC_MACHINE_SP
- _UC_MACHINE_FP
- _UC_MACHINE_PC
- _UC_MACHINE_INTRV
These tests attempt to access and print the values from ucontext, without
interpreting the values.
This is a follow up of the _UC_MACHINE_FP() introduction.
These tests use PRIxREGISTER, and require to be built with -D_KERNTYPES.
