# Progress #

* TCWG-1050, GDB 8.0 release. [4/10]
** Fix the new fails about the size of wchar_t on aarch64, by setting
it to 4 in default. Patch is pushed to master and 8.0 branch.
** Intel btrace python api patches are ready to commit. No idea why
he doesn't push yet.

* TCWG-1040, Review SVE patches. [4/10]
** Review some SVE GDB patches, and approved part of them. Leave the
controversial part there. Some of them are blocked by my Class-fy
regcache patches.
** Class-fy regcache. Patches are approved. Will push them in later.
Then, I'll update my unit test to value/register conversion gdbarch
hooks, and post them next week.
** GDB target description change, the preparation for adding more
hardware features, like PAUTH and SVE, and their arbitrary
combinations.
GDB side changes are done, and take i386-linux as an example to
demonstrate the the benefit of the changes.

* Misc, [2/10]
** Rebase my GDB disassembler patch, which unify the disassembler
selection in both gdb and objdump.

** Explain the GDB behavior to Linaro kernel guy who is working on
single-step in kgdb.

** Read some paper on dynamic slicing, and think about how to do it on
GDB for aarch64/arm.

# Plan #
* Holiday on Monday.
* Review kernel-awareness patches,
* Upstream my patches about unit test to value/register conversion
gdbarch hooks.
* Post my GDB target description change as an RFC, collect comments,
and think about the changes in GDBserver side (which is harder).
