Progress:
[VIRT-349 # QEMU SVE2 Support ]
10 of N insn groups implemented.
Annoyingly, there doesn't seem to be a summary of new insns, so confirming that
all of the insns have been implemented.
[VIRT-327 # Richard's upstream QEMU work ]
Patch review. Mostly Phil's arm --disable-tcg set.
Cleanup for some of the new Coverity reports.
Flush tcg patch queue.
[GCC]
Two revisions improving TImode comparisons for aarch64 (PR94174).
https://gcc.gnu.org/pipermail/gcc-patches/2020-March/542447.html
[Kernel]
Follow-up on a discussion a few weeks ago re __range_ok. The gcc cmpti patch
set is in support of that, but I also found a much better solution for constant
sized checks.

* BFD Linker:
- GNU-629: non-contiguous memory support: minor follow-ups
* GCC upstream validation:
- reported a couple of failures/regressions
- PR90378 working on reproducing a non-functional code problem with spec2006
on arm with LTO and -Os. Looks like a stack corruption issue
* GCC:
- comparing testsuite results for cortex-m3 and cortex-m33 with
cortex-a9 to check what cortex-M problem there are.

- infra fixes / troubleshooting / reviews

* FDPIC GDB
* GCC/cortex-M
Progress:
* VIRT-65 [QEMU upstream maintainership]
- Softfreeze this week, so a lot of pull request handling, and
one last small arm pullreq to put together and send out
- Our Coverity Scan setup was broken (the person who usually does
the builds updated his machine to a newer Fedora which broke the tool).
I pulled up an old patchset I had from a year ago which scripts things
so you can do a build-and-upload automatically via Docker so that
we're not dependent on one person for this. This took longer than I
expected as there were a bunch of things that needed fixing both in
the scripting and in bits of the codebase that the tools warned about.
Patch series sent.
- When we did get a Coverity run through, it reported 112 new issues;
spent some time going through and triaging them (lots of false positives
but also lots of real bugs)
thanks

Howdy,
1st post on this list.
I just tried the windows binaries found on the latest-7 release site,
namely of:
gcc-linaro-7.5.0-2019.12-i686-mingw32_arm-linux-gnueabihf
When I go into the bin folder and enter:
.\arm-linux-gnueabihf-gdb.exe --version
It outputs nothing, just returns. The version I used prior, 7.3.1, still
works as supposed.
Notable is that from 7.3.1 to 7.5.0, the gdb.exe size grew from ~96MB to
~128MB.
I re-downloaded the whole tar again and replaced the bin folder, no change.
I can actually *build* a C++ project with those binaries, though, and
the output executable works.
Only GDB seems to be affected so far.
[VIRT-344 # ARMv8.5-MemTag, Memory Tagging Extension ]

Updated a forgotten patch vs sve fmla/fcmla.
Oodles of patch review.

Progress:
* VIRT-65 [QEMU upstream maintainership]
- More documentation cleanup (splitting the Arm boards section
up into one page per board)
- Various patch review
- Put together last large pull request before softfreeze hits next week
- Fixed the Windows installer generation, which I broke in the
process of moving the HTML docs around
- Fixed read buffer overrun in i82596 device model spotted by coverity
- Fixed a user-experience papercut that's been bothering me for years:
for arm you needed to specify '-M virt' to avoid an error even if all
you wanted was the '-cpu help' or '-device help' output.
* VIRT-241 [QEMU ISA Support for A-profile]
- Jira gardening: split out the optional parts of each architectural
tick sub-epic, and added the new 8.6 tasks
thanks
