* Two days off [4/10]

# Progress #

* TCWG-685, GDB 7.12 release. [3/10] Fix one bug that AArch64 GDB doesn't recognize new "STP with base register" instruction in prologue. Recent GCC https://gcc.gnu.org/ml/gcc-patches/2016-07/msg01933.html starts to generate that instruction in prologue. Fix it in both master and 7.12. Successfully build armhf toolchain with latest gcc/glibc. Run GDB tests with the new toolchain. Test results are OK, except fails when tests are compiled with -march=cortex-a15. It isn't a release blocker. Open TCWG-756 for it and will look into these fails later.

* GDBserver build failure. [1/10] Review the patch fixing GDBserver build failure with latest glibc. Patch is OK, but make sure it can be merged to master/7.12/7.11, as we are still using GDB 7.11.

* Prelink. [1/10] prelink causes some GDB tests failures, so I look at it. prelink isn't active, because I can't see any mails in archive since 2013. ARM is supported, but AArch64 isn't.

* Misc, [1/10]. Set up email 2fa.

# Plan # * GDB 7.12 release. * Upgrade the linux kernel on my juno board.
