be230add88 Rename test-varargs' to Ltest-varargs' 
This testcase only uses the local-only `unw_backtrace()' from libunwind,
and a "generic" build of this test case would not be interesting.

c2d6f85a0a Use __sync builtin atomics on all architectures if available 
We can use the __sync builtin atomics also on other architectures than
IA64. GCC 4.7 documentation notes that these builtins are ``legacy'' --
adding support for the newer GCC __atomic atomics should be fairly easy.

9a3565ddc1 Simplify `sos_alloc()' implementation 
Instead of maintaining a pointer to the `sos_memory' array, maintain an
index that tells the next free position. When atomic operations are
available, the allocation boils down to a single fetch-and-add
operation.

26fc1563fb Align `sos_memory' to MAX_ALIGN 
We give aligned pointers from the `sos_memory' array, so any non-aligned
bytes are only wasted.

c36a14f245 Workaround non-power-of-two i386 sizeof(long double) in src/mi/mempool.c 
To ensure that we return properly aligned pointers from sos_alloc(),
MAX_ALIGN must be a power-of-two. On i386 the power-of-two assumption
fails as sizeof(long double) = 12. Fix this by rounding up to 16.

e6edad069c Use GCC __BIGGEST_ALIGNMENT__ for sos-pool MAX_ALIGN 
Use the __BIGGEST_ALIGNMENT__ macro provided by GCC for sos_alloc()
allocation alignment. The macro gives ``the largest alignment ever used
for any data type on the target machine you are compiling for.''

__BIGGEST_ALIGNMENT__ also has some other nice properties, e.g. it is
power-of-two on all architectures (note that on i386, sizeof(long
double) = 12), and on some architectures (e.g. SuperH) the alignment
requirement can be lower than sizeof(long double).

9184535486 ptrace: add more Debug to access_reg 
This was useful in debugging issues with the libunwind-ptrace code on
ppc64.

3d6f7479b0 ptrace: check for NULL arg. 
tdep_get_func_addr in ppc64 passes NULL for the last argument of
as->access_mem.  tdep_get_func_addr is called by elf_w(lookup_symbol),
which in turn is called by elf_w(get_proc_name_in_image).

elf_w(get_proc_name_in_image) is part of the API, and is only passed an
unw_addr_space_t, not a unw_cursor_t, meaning that we cannot recover the
UPT_info on the PPC64 platform.

This could be fixed by giving libunwind the knowledge to perform
relocations itself, thus not needing to look at the running image to
determine function addresses.
