All,
During Connect the suggestion was made that each working group should have
its own IRC Channel for discussions and topics relating to the group in
particular (as opposed to #linaro which is 'generic' Linaro conversations).
Therefore I have just set up #linaro-tcwg on Freenode for the Toolchain
Working Group.
This channel is public and open to anyone who wants to talk with the TCWG
group about anything toolchain related.
Thanks,
Matt

Toolchain Working Group, Linaro
== This Week ==
* GNU-659 (LTO calculix regression)
- Started upstream discussion
* LLVM-611 (Tune lowering heuristic to blx for code size)
- Addressing upstream feedback for patch to fold tLDRpci, tBLx -> tBL
in foldMemoryOperand hook
- Added new heuristic to ISel, for follow up patch.
* LLVM-639 (Better idiom for comparing 32-bit values on arm)
- Started working on patch
== Next Week ==
- Continue ongoing tasks
1 day off
== Progress ==
* GCC upstream validation:
- reported several regressions
- committed testcase fixes
* GCC
- patch for PR94758 (-mpurecode and cortex-m23) applied to
thunk/gcc-10/gcc-9. Bug closed, but opened several others to track
performance improvements with -mpurecode
- PR96768: switch tables for thumb-1 with -mpure-code. Patch sent,
discussion on-going
- PR96769: WIP
- PR71233: missing ACLE intrinsics. I will first have to update the list
* benchmarking:
- Scripts to run coremark on stm32 now merged, working on using them
in production
* misc:
- infra patches/reviews
- internal support, leading to GCC testsuite cleanups for cortex-m
== Next ==
* GCC/cortex-M testing improvements & fixes
* cortex-m benchmarking
Progress:
* VIRT-65 [QEMU upstream maintainership]
+ Just the usual code review and pull request work.
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
+ I have all fp16 insns (both VFP and Neon) implemented now, and the
VFP patches have been reviewed. Just need to track down a few last
test failures and then I can send the Neon patches out for review.
thanks

Progress (short week, 2 days):
* VIRT-65 [QEMU upstream maintainership]
+ We got 5.1 out the door. I think this is the first release
in the many years I've been handling them where we managed to
avoid needing an rc4.
+ Spent a fair amount of time helping Paolo to debug his conversion
of the QEMU build system to Meson. We managed to land that today.
+ First of the KVM Forum programme committee meetings
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
+ More progress with fp16 support work; another handful of insns done.
thanks
