== This Week ==
* PR88833 (4/10)
- Started investigating the issue, it seems one of the code-movement
RTL passes like cse2
do not remove identical register copies resulting in extra register move.
* PR88837 (5/10)
- Patch almost approved offline by Richard, suggested me to move
discussion upstream.
- Observed "strange" issue with return value vectors on qemu for
run-time tests for fixed-length vectors. Turned out due to mismatch
in vector-length at compile and run time -;)
- Trying to run SVE tests with qemu.
* Misc (1/10)
- Meetings
== Next Week ==
- Continue ongoing tasks
[LLVM-122] BTI and PAC support in LLD
Implementation now working, have written BTI tests, next step is
finishing off PAC tests.
[Misc]
Helped out debugging an asm-goto problem on ARM targets.
Investigated a GNU ld LMA overlap when VMA and LMA got out of sync.
Helped out with CMSIS use of ld scripts when using a fast-model,
needed to get LMA == VMA for program header covering BSS.
QEMU Tooling ([VIRT-252])

Progress:
* VIRT-65 [QEMU upstream maintainership]
+ sent patchset fixing a handful of simple GICv3 bugs
+ usual codereview work
+ sent out a sketch of how we can transition our documentation
from the current texinfo manual to a set of sphinx manuals
+ had a look at the practicalities of converting our hand-written
VFP decoder to 'decodetree' -- this may be the easiest way to
support FPU configs which only support single-precision, like Cortex-M33
thanks

== Progress ==
* FDPIC
- GCC: Updated patch 03/21 with changes in the handling of -static
