== This Week ==
* GCC:
(i) PR86753 - Addressing upstream suggestions, pivoted to another approach.
(ii) PR91272 - Patch fixes issue but not correct approach, need to rework it.
(iii) PR78736 - Submitted patch upstream.
== Next Week ==
- Continue ongoing tasks.
== Progress ==
* Investigate running benchmarks in containers [TCWG-1513]
- Cleaned and uploaded scripts for comments
- mcf still hangs, but only when run with clang; investigating root cause
* SVE IR fuzzer [LLVM-586]
- Made some progress with the prototype but it still needs work
* Re-running 8.0.1 release on AArch64 since the archive on
llvm.org/releases seems to be broken
[VIRT-263 # ARMv8.1-VHE Virtual Host Extensions ]
Reorg ARMMMUIdx again; this time, do not overlap
EL1&0 and EL2&0 mmu_idx. This makes debugging a
bit easier.
Fix one more bug in EL2&0 selection. This was not
the last, because a nested kernel does not yet boot.
[VIRT-327 # Richard's upstream QEMU work ]
Another round of aa32 decodetree patches.
Another round of arm hflags patches.
Review of and some patches for cpu watchpoints.

Progress:
* VIRT-65 [QEMU upstream maintainership]
+ sent fix for LP:1840922 (incorrect handling of branches to
M-profile exception-return magic addresses in linux-user mode)
+ some more work on requirements for JIRA KVM related issues
+ started reviewing RTH's monster decodetree conversion patchset
(and made it nearly halfway through it)
thanks

== Progress ==
* GCC:
- FDPIC: handling feedback.
* GCC upstream validation:
- no issue to report this week.
* Binutils:
- Non-contiguous memory regions support in the BFD linker: not started yet.
* misc:
- infra fixes / troubleshooting
- qemu-4.1 confirmed OK for GCC validations
- trying validations for cortex-m33, found a few issues in GCC and a
small one in QEMU
- a bit of Jira
== Next ==
GCC:
- handle feedback on FDPIC patches
- binutils/linker support for non-contiguous memory regions
- GNU-583
- GCC upstream validation: Add a config for cortex-m33 (v8-m)
- Reorganised buildbots to remove some of the duplication between v7
and v8 AArch32 to free up more v7 hardware.
- Got final code-size information and wrote my slides for Linaro Connect
- Track down an AArch64 specific LLD problem due to a recent change,
now resolved.
- Wrote worst case thunk/veneer convergence patch to help move through
an iterative symbol assignment algorithm.
UK Bank Holiday Monday
== This Week ==
* GCC :
(i) PR83756: Addressing feedback from upstream.
(ii) PR90724: Committed to trunk.
(iii) PR91272: Started working on patch.
(iv) PR88839: Merged fix from sve-acle-branch to trunk.
* Validation
(i) Patch to separate build and test steps in tcwg_gnu.
(ii) SVE validation
== Next Week ==
- Continue ongoing tasks
== Progress ==
* Investigate running benchmarks in containers [TCWG-1513]
- Discussed the noise levels with the team and we decided to
continue with this
- mcf hangs, need to investigate the cause
- WIP: cleaning up the scripts so I can send a sensible patch for review
* IR SVE reviews [LLVM-545]
- Looked at some patches but didn't have much to add to what other people said
* SVE IR fuzzer [LLVM-586]
- Started prototyping
- The fuzzer relies a lot on inserting constants, and since we can't
produce SVE constants yet I'll have to dig in and get it to also use
function parameters
- Need to add operation descriptions for SVE
* Buildbot babysitting
- Reported an issue
