Dimitry Andric 2d82f915c2 For the asan_symbolize.py script, use addr2line as the default system 
symbolizer on FreeBSD too.  This allows the asan-symbolize-bad-path.cc
test to succeed.

Alexey Samsonov 1b76da6a6c Support inline functions symbolization in Addr2Line symbolizer. 
Patch by Maxim Ostapenko!

Summary:
Right now, Addr2Line symbolizer in asan_symbolize.py doesn't support inline functions symbolization. This might be a useful feature for using ASan on embedded systems.

Test results:

$ cat test.c

static inline void FooBarBaz() {
  __sanitizer_print_stack_trace();
}

int main() {
  FooBarBaz();
  return 0;
}

$ clang  test.c -fsanitize=address -g -O2 -o test.x && ./test.x &> /tmp/test.log
$ ./projects/compiler-rt/lib/asan/scripts/asan_symbolize.py  -l /tmp/test.log

Evgeniy Stepanov 84d30ba43a [asan] Support 'su' rooted devices in ASan setup script. 
Android devices may not support 'adb root', but be rooted with 'su'
binary. This patch makes it possible to install ASAN to such
devices. When --use-su flag is specified, most 'adb ...' commangs are
changed to 'adb su -c "..."'.

Some other notes:
 * 'readlink' changed to 'ls -l', since not all devices have readlink
   in their firmware.
 * removing ASan library step moved to very end, because 'su' may not
   run properly without this library until shell will be restarted.

Nico Weber 406f640a68 Make asan_symbolize.py not crash on Windows. 
asan_symbolize.py isn't needed on Windows, but it's nice if asan has a unified
UI on all platforms. So rather than have asan_symolize.py die on startup due to
it importing modules that don't exist on Windows, let it just echo the input.

Alexander Potapenko 7a0f81a9b7 [ASan] Allow the users of SymbolizationLoop to make use of the --dsym_hint option in llvm-symbolizer 
Let the users of SymbolizationLoop define a function that produces the list of .dSYM hints (possible path to the .dSYM bundle) for the given binary.
Because the hints can't be added to an existing llvm-symbolizer process, we spawn a new symbolizer process ones each time a new hint appears.
Those can only appear for binaries that we haven't seen before.

Evgeniy Stepanov 9e922e7d24 [sanitizer] Android build cleanup. 
* Detect Android toolchain target arch and set correct runtime library name.
* Merged a lot of Android and non-Android code paths.
* Android is only supported in standalone build of compiler-rt now.
* Linking lsan-common in ASan-Android (makes lsan annotations work).
* Relying on -fsanitize=address linker flag when building tests (again,
  unification with non-Android path).
* Runtime library moved from lib/asan to lib/linux.

Alexey Samsonov 968a358974 [ASan] Add new options for asan_symbolize.py script. 
The patch adds new features in asan-symbolizer script which are helpful for using ASan on embedded systems:

1) add cross-compile prefix for binutils
2) define path to sysroot with sanitized binaries

Features are enabled by command line options.
The patch also extends command line interface with help option.

Evgeniy Stepanov 322e89c4e2 [asan] Install asan_device_setup to bin/ when targetting Android. 
asan_device_setup is a utility that prepares a device to run code built with
ASan. Essentially, it installs ASan runtime library into the system. For this
reason, it has to be at a predictable relative path from the runtime library
itself. We also plan to distribute this utility, packaged with runtime library
and maybe llvm-symbolizer, to the users.
