by Yao Qi

# Progress # * TCWG-162, Aarch64 non-stop debugging (or displaced stepping). [4/10] After testing, patches are posted upstream. * In order to review one c++ debugging patch, learn some C++ abi, vtable and VTT, etc. Understand gcc dump by -fdump-class-hierarchy. [3/10] * Fix GDB cxx build breakage caused by my patch. [1/10] * Ask the effect of -fstack-check=specific to AArch64 prologue. GDB needs update. [1/10] * Misc, email, meeting. [1/10]. # Plan # * TCWG-162, commit patches if no objections. * TCWG-387, use libopcodes to decode instructions in GDB. -- Yao
