# Progress #

* TCWG-984, PR 20939, GDB aborts if there is an error in disassembly. Done. All patches are committed to mainline. [3/10]

* Patch reviews, a lot, [5/10] ** Hold one of ILP32 BFD patch because it may affect aarch64 GDB, Reviewed ILP32 GDB patch, and convince them not to add new target descriptions for ILP32, to make our life easier in the future. Otherwise, we need two copies of target description for each new hardware feature, such as v8.3, SVE, etc. ** Try to hold one disassembler options patch, which affects ARM and GDB. Gave some comments on the interface design, but looks I am late. ** Finish the review on DW_OP_implicit_value. Met some grey area in DWARF spec.

* Atomicity of concurrent modification on ptrace. [1/10] It is unclear weather debugging can modify memory for one thread while other threads are running. After the discussions with some kernel guy, PTRACE_POKETEXT is atomic, but GDB use it in a non-atomic way when writing 2-byte aligned 32-bit thumb-2 instruction. Suggested a workaround upstreams.

* Misc, meeting [1/10]

# Plan #

* ILP32 patch review. * Carefully read IBM's kernel debugging patches. * Set up AArch64 bare debugging with GDB, OpenOCD, JTAG and HiKey. Soldering is needed.
