[VIRT-327 # Richard's upstream QEMU work ]
More time than I expected on float128_muladd, adjusting the codebase to share
code with float64_muladd.
[VIRT-339 # ARMv8.5-BTI, Branch Target Identification ]
Posted v12, adjusting one of the smoke tests vs a distro linker bug (fixed in
mainline).

Hi,
I am new to toolchains. I would like to know information on building
toolchains for different architectures.
My objective is to build a cross compiling toolchain for AARCH64 BE
target on the RHEL7.6 build system. It would be great if you can give me
pointers on how to compile toolchains. Do we have any Wiki pages on
building linaro toolchains for different architectures?
Appreciate your help.
Regards
Suresh

Progress:

+ another round of code review and target-arm queue wrangling
+ found and fixed an edge-case bug in setting Q flag in SMLAD insn
+ fixed a GICv3 emulation bug where we didn't ever raise
maintenance interrupts
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
+ went through Arm ARM and identified exactly what the "v8.1M changes
which aren't part of a named architectural feature" are (for
QEMU-409 subtask)
+ implemented some parts of NOCP handling that were left as TODO comments
for being v8.1M-specific
+ implemented conditional-select insns (CSEL, CSINC, CSINV, CSNEG)
+ implemented low-overhead-loops and branch-future (in the 'trivial'
don't-cache-anything way the architecture permits)
thanks

Progress:
* VIRT-65 [QEMU upstream maintainership]
+ Got a v6 series sent to the list of the conversion of QAPI
doc-comments into rST/Sphinx. This took most of the week,
following Markus' detailed review on the v5 (and involved
some wrestling with Meson). Optimistic that this can get into
master now...
thanks

[VIRT-327 # Richard's upstream QEMU work ]
Send out tcg patch queue.
Prototype a disassembler using llvm. Not ideal.
If we proceed with this further, we should probably
schedule time for it, because the job is not small.
Updating the capstone submodule; a couple of rounds
converting that to meson.

Hello Linaro Toolchain Working Group,
Do you plan to bring linaro-tk1-03 back online soon?
If not, I'll remove it from the LLVM buildbot this Friday.
Thanks
