2015-09-14Support inline functions symbolization in Addr2Line symbolizer.Alexey Samsonov

2015-02-16[asan] Support 'su' rooted devices in ASan setup script.Evgeniy Stepanov
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.

asan_symbolize.py isn't needed on Windows, but it's nice if asan has a unified UI on all platforms.

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.

2014-02-27[asan] Install asan_device_setup to bin/ when targetting Android.Evgeniy Stepanov
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. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@202362 91177308-0d34-0410-b5e6-96231b3b80d8
