9de666d141 Simplify DWARF source handling 
Build DWARF source files into automake convenience libraries to
eliminate duplication in arch-dependent library build rules.
Adds a configure-time check to determine whether to use them.

54752e0df0 Implement getcontext for x86 
Greetings,

Attached patch implements getcontext for x86.

Motivation is the same as:
http://lists.nongnu.org/archive/html/libunwind-devel/2008-06/msg00009.html

This also fixes check-name-space on x86.

Tested on Linux/86 with no new failures.

Thanks,

4b8404d153 Remove the special casing of ia64 for GetIPInfo() 
This rule (no IP adjustment on ia64) may be correct for locating the right FDE.

Unfortunately the same adjusted/unadjusted return address is being used also by
__gxx_personality_v0() to locate the right call-site (the try {} block) for
unwinding.  And this case is already sensitive for off-by-one PC values.
Unlike the FDE location where the function prologue + epilogue make it immune
against off-by-one PC calculations.

Therefore suggesting to unify it with non-ia64 case.

2fce54102c Implement _Unwind_GetIPInfo() as required by the C++ ABI 
Provide a special implementation for ia64, because the unwind
information is such that an IP adjustment is not necessary before
looking up unwind info.

Bad things happen if libunwind only provides parts of the ABI and
the rest come from libgcc.

ef29eade44 This patch eliminates one system call per unwind by not using the 
getcontext in libc.

Also cleanup the namespace (check-name-space passes on x86_64 now).
Replace uses of offsets.h with ucontext_i.h.
Rename _x86_64_setcontext to _Ux86_64_setcontext.

TBD: Add CFI annotations for get/setcontext.

e6b9f350f7 Introduce a tdep_get_func_addr_hook() in the ELF lookup_symbol() 
routine and add address-space argument.  This is needed because on
PPC64, a the function-name symbol refers to a function descriptor
(unlike, for example, on ia64, where the @fptr() operator is needed to
refer to a function descriptor).  Thus, in order to look up the name
of a function, we need to dereference the function descriptor.  To
make matters more "interesting", the function descriptors are normally
resolved by the dynamic linker, so we can't get their values from the
ELF file.  Instead, we have to read them from the running image, hence
the need for the address-space argument.
