Stop mapping _UC_MACHINE_FP() to a register as it is not supported by CPU.
There is need to use in code __builtin_frame_address() inlined in the code
to get the frame pointer.

Return a constant value 0 instead. New value does not pretend to return
a meaningful value.

While there, fix the definition of _UC_MACHINE_SET_PC as it didn't contain
the pc argument in the definition.

Update some of the _UC_MACHINE* macros even though gregs[] aren't tied to anything yet

Add a dummy implementation of _UC_MACHINE_INTRV() for ia64

This fixes a build problem in src/tests/lib/libc/sys/t_ucontext.c.

This needs to be revisited once the port will get more mature.

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@.
