[ACTIVITY] 20th - 24th March

[Yao Qi]

~ Progress ~

* TCWG-1050, GDB 8.0 release. [6/10]
** Pushed a fix to AArch64 process record bug on PRFM instruction.
AArch64 native test looks good now.
** Start to look at ARM native test, triage the fails in
watch-bitfields.exp. Test doesn't fail on old Linux kernel, likely
a kernel bug. Further analysis is needed.
** Request reverting Intel btrace python interface before release, as
they are too btrace-specific.
** Fixing a bug about thread_info refcount issue. Testing the patch.

* Discussion on RTOS awareness in debugging. OpenOCD people want GDB
aware more about different RTOSes. [1/10]

* TCWG-1040, SVE patches review, [2/10]

* Misc, [1/10]

~ Plan ~

* Take a look at native ARM testing, and cross testing.
* Post my fix to thread_info refcount issue.

Achievements:
[TCWG-614] Range extension Thunks
- About 3 hours in total of rebasing due to upstream refactoring
- Have finished the non-linkerscript tests and fixed all the bugs
detected by them
- Started the linkerscript tests, no problems found so far

[TLS]
- Some explanation to upstream of how ARM TLS works
- Discovered that upstream have broken TLS global-dynamic for
executables, I have a fix but will need to write a test case.

Plans for next week:
- Euro LLVM Monday, Tuesday
- Continue with TCWG-614
-- Try and link clang (> 30 Mb) to test range thunks on some real programs
-- Aim to get something ready for upstream review by end of week, may
slip to beginning of next week depending on if I find any hard to
debug problems.
