af2503e223 Fix bug in libunwind-ptrace which can cause reading of random data. 
(maps_next): After reading less than a full buffer of data, copy
remaining data to the top of the buffer so as to maintain the
invariant that all data between mi->buf and mi->buf_end is valid.
This avoids maps_next() parsing uninitialized data.

cbd8648b33 Make libunwind compile with recent versions of GAS. 
Don't test read-only access to F0 and F1 registers --- according to
the SCRA manual, those locations cannot even be expressed in SPILL
descriptors and newer versions of GAS (as well as IAS) won't accept
.spillreg directives targeting those registers.

f176ad6fc6 Bring git v0.98.5 tree in sync with released v0.98.5. 
Sadly, the conversion from Bitkeeper -> CVS -> git wasn't perfect.  Or
so it seems.

4479427266 ia64: Fix off-by-one bug reported by Todd L Miller. 
The rationale for this fix is as follows: for the ALIAS directive, RLEN
specifies the number if instructions for which the region behaves like
the aliased code.  For example, if RLEN=1 then the code follows the
aliased region for 1 instruction and the valid WHEN values should be 0
and 1.  However, with the unpatched code, we would have allowed for -1
and 0, which is wrong.

7e57252750 Don't check for libatomic_ops for now. We don't really need it for 
x86 and ia64 and checking for it causes a dependency for libunwind
on libatomic_ops.so, which is not what we want.

3c12faa059 Fix build of static libunwind.a: turns out libtool doesn't like 
full-path archive library names.  Instead, we need to use -lgcc
(and hope that GCC doesn't pick up the dynamically-linked version!).

Longer term, a better solution might be to drop the -nostdlib linker
option and to use --as-needed instead to avoid recursive references
to -lunwind.
