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.

lwp.h file.

Clean up the <sys/ucontext.h> <-> <machine/mcontext.h> interface up
a little:
- Define _UC_MD_BIT* constants for the available machine-dependent bits,
and use those constants to define the machine-dependent bits as well
as the machine-independent bits that have machine-dependent values.
- Explicitly generate an error if _UC_TLSBASE, _UC_SETSTACK, or
_UC_CLRSTACK are not defined by <machine/mcontext.h>.

thorpej | Implement _UC_SETSTACK / _UC_CLRSTACK.

Harmonize the namespace of fast TLS base pointer getter functions
Protect __lwp_getprivate_fast() with _RTLD_SOURCE, _LIBC_SOURCE and
__LIBPTHREAD_SOURCE__.
Include in this namespace <sys/tcl.h> and use __BEGIN_DECLS/__END_DECLS
for the sake of consistency.

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@.

For fast lwp_getprivate, just do the chmk $SYS_lwp_getprivate inline.
|

| 07-Jan-2012 |
chs | define _UC_TLSBASE and use it to pass the TLS pointer to setcontext().
since there is no available space in ucontext_t on vax, pass the
TLS pointer on the stack referenced by the ucontext_t instead.
suggested by joerg.

- 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];

--
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.
