[ACTIVITY] 22 - 26 August 2016

[Diana Picus]

== Progress ==

* [AArch64] Support for label arithmetic in the assembler [TCWG-710] [9/10]
- Patch in upstream review
- While adding more tests for the patch above, I noticed that we're not
encoding the lsl #12 on add/sub immediates correctly
- Submitted a patch to fix that as well

* Misc [1/10]
- Ran more precommit tests for last week's reverted revisions

== Plan ==

* Handle special cases in AArch64InstrInfo::GetInstSizeInBytes [TCWG-757]

[Peter Smith]

== Progress ==

- Got back from Sabbatical and caught up with email/events

- TCWG-610 Support for ARM Exceptions in lld.
Implemented support for SHF_LINK_ORDER and .ARM.exidx in lld, have
this working and tested for
images (both with default and linker scripts) and relocatable ld -r
with the default layout. Currently it looks like relocatable outputs
with linker scripts aren't working at all right now.

== Plan ==
- Hope to send to upstream review next week.
- Write the first pass of the LLVM Cauldron presentation.

== Planned absence ==
Monday 29th August is UK national holiday

# Progress #

* TCWG-685, GDB 7.12 release. [4/10]
Finish all native testing on ARM. Triaged tests result. Only find
one fail that test assumes HW watchpoint is always available.
Reported it upstream, but need more thoughts on how to fix it.
Both AArch64 and ARM GDB is in a good state, in terms of test results.

* TCWG-533, Remove global variable arm_override_mode. [2/10]
It is paused by 7.12 release, and work on it again. 10 patches are
ready. Being regression tested.

* Analyse the kernel behaviour on single step over fork. [4/10]
Upgrade juno kernel to 4.7.0-rc4+, and verified Will Deacon's patch.
http://lists.infradead.org/pipermail/linux-arm-kernel/2016-August/451711.html
With the patch, GDB can correctly single step over fork, however,
GDB is still broken if there is a breakpoint. Write a small
reproducer, but doesn't trigger the problem. It might be a GDB bug
or kernel bug.

# Plan #

* Resume works interrupted by 7.12 release.
