~ Progress ~

* TCWG-965, Investigate doing unit tests in GDB. [3/10] Done. The first unit test to AArch64 prologue analyser is pushed. The unit test is running on GDB buildbot on different hosts (x86, s390, etc). The patch review takes a while because it is my first patch written in C++11. Need some unit tests to ARM prologue analyser too.

* TCWG-416, Improve GDB performance in remote debugging. [4/10] Use code cache in AAarch64 prologue analysis, and it is improved from 10s to 3s!

* TCWG-333, Fix gdb.base/func-ptrs.exp fails in thumb mode. [1/10] Preparatory patches are committed. Think about the next step. I have to change expression evaluation in GDB.

* Misc, [2/10] ** Upstream patches review. Reviewed OpenRISC and FreeBSD/mips patches. ** GDB linux kernel awareness discussion. GDB is unable to access kernel memory when program stops in user space (by ctrl-c). Discussed some ways to avoid teaching GDB setting MMU. ** Some input and discussion on SVE.

~ Plan ~

* TCWG-964, more unit tests on ARM prologue analyser, * TCWG-416, measure performance improvement with -fstack-protector on ARM (with both -marm and -mthumb). * TCWG-333,
