[Libunwind-devel] PowerPC64 Support finished

[Jose Flavio Aguilar Paulino]

Hi People,

Well, finally I finished the libunwind patch for Power64!
First, 

- I have to create a new kind of registers VREGS, because PowerPC has
vector registers (Special ones 128bits longs only for special
instructions) and the libunwind has General Use Registers and Flating
Pointer Registers. So I had to create a dummy register array in x86.

- Second, in some functions I had to add the a void pointer to ARGs,
because I need in some cases to pass special parameters.

- Third, I had to add new generic file for function pointer translate:
Gget_func_addr.c. This is necessary because functions are called
indirectly in Power. So, as in GDB, I need to create a dummy function
for x86.

- Fourth, I add some Power specific tests

Well, I thinks thats all..
One last thing, I have corrected the libunwind for x86 because its the
only one Arch that I have available besides Power64, so problems will
occur in other Archs, I can work with you to solve them.

Thanks,
Jose Flavio Aguilar Paulino

Ps: Its a big patch, more than 400kb.
