f4a8df5f4f338f1a12c25213227e98b34b42447f 08-Mar-2014 Christopher Ferris <cferris@google.com> Fix maps caching for local processes.

It is possible for the map to change while running libunwind. For example,
if lots of threads are doing local unwinds at the same time. Allow the
cached map to regenerate when it detects this case.

Included in this change is a refactor of all of the os code so that it can
also be used to do caching. This is a prelude to being able to attempt to
push the code upstream.

Also, this moves the code back closer to the original upstream code.
Hopefully, this will allow me to upstream all of these changes.

16b95a68caaa7e021209e2cd6a877ae1e558f740 23-Jan-2014 Christopher Ferris <cferris@google.com> Add speed-ups to libunwind.

Add caching of /proc/self/maps data structures.

Add caching of elf image maps attached to the maps data structure.

Add a set of new map api functions to handle creation/destruction of the
maps by external code.

Remove the creation of the maps data structure in the local address space
init.

7d46a21e0a2cb561e4cad57b101a7137e01023dc 14-Nov-2013 Christopher Ferris <cferris@google.com> For current process, check memory accesses.

When attempting to unwind the current process, the library simple reads and
writes to memory for memory accesses. Unfortunately, if an unwind winds up
with invalid data, then the process can segfault. Add a guard to all memory
accesses that verifies that reads/writes are valid before attempting them.

For now, this guard is a nop on all systems except linux systems.

Also, modify the adjust_ip function to use the access_mem function
so that all reads go through the right function.

- Add tdep macro for {dwarf,ia64}_find_unwind_table so that ia64
doesn't try to use dwarf code.
- Fix extraneous #if.
- Fix mistyped filename in Makefile.am.
- Link ia64-specific tests with correct libraries.

e2962af9d31266761700b431da894421c0d757ec 06-Apr-2011 Arun Sharma <asharma@fb.com> Implement a cheaper getcontext()

Since the fast unwinding code path doesn't need the full context,
a faster target dependent getcontext is implemented.

5f38f35d5d6c78aafa6da20845d9ceff74af00f8 01-Apr-2011 Lassi Tuura <lat@cern.ch> Drop a call frame in tdep_trace and avoid a call to unw_step.

Dropping the extra frame for unw_backtrace itself using unw_step is
approximately 15% slower than skipping the frame in tdep_trace. So
drop the frame in the latter, and make the function a private
implementation detail for libunwind, not an exported interface.

Also moves unw_getcontext call back into unw_backtrace to avoid an
extra call frame in case slow_backtrace does not get inlined into
unw_backtrace.

Adds new function to perform a pure stack walk without unwinding,
functionally similar to backtrace() but accelerated by an address
attribute cache the caller maintains across calls.
