(Upgraded my laptop to Fedora 28, which lead to...)
Posted a patch for gcc 8 Werrors.
Posted patches for clang 6 Werrors.
Sent pull for Emilio's TranslateOps patches.
Sent pull for my openrisc decodetree patches.
Sent pull for tcg-next.

Posted two rounds of fp16 patches.
[VIRT-198 # QEMU: SVE Emulation Support ]
Most of this week's work was on indirectly related patch sets. In particular,
fp16 and atomics. The last round of check-gcc testing had
FAIL: gcc.dg/vect/slp-multitypes-2.c execution test
FAIL: gcc.target/aarch64/advsimd-intrinsics/vldX.c -O0 execution test
FAIL: gcc.target/aarch64/advsimd-intrinsics/vqtbX.c -O0 execution test
as the only remaining (relevant) failures. I believe that the latter two are
generic tcg failures that are cured by this week's tcg-next pull, but have not
yet re-based everything to be sure.

[TCWG-1236] Android on LLD
Android team have switched to LLD by default for most modules. Looking
to switch over the course of a release.
I've been looking at the list of modules that don't work with LLD and
investigating.
- Sent some patches upstream to add some missing features needed by
Android such as --keep-unique
[Other]
Reviewed some patches for LLD and MC
Sent a patch upstream for support of the "S" constraint in AArch64
inline assembly.
Progress: [short week, 3 days]
* VIRT-65 [QEMU upstream maintainership]
+ code review
- RTH's FP16 bugfixing patchset
- Alex's float-to-float conversion patchset
- fixes to SD card CRC checking
- various minor linux-user cleanups
* VIRT-164 [improve Cortex-M emulation]
+ working on emulation of Memory Protection Controller: have a working
prototype that needs a few loose ends tidied up
thanks

Hi, Maxim
Do we have any build for native aarch64 toolchain GCC 7.3?
I checked snapshots.linaro.org:
https://snapshots.linaro.org/components/toolchain/gcc-linaro/7.3-2018.04/
But it only has x86 versions.
Somebody pinged me from the 96boards community to ask for that. He
asked for GCC 7.3. What being used in ERP 17.12, as I checked, is GCC
6.3.
Thank you very much.
Best regards,
Guodong Xu
Progress:
[Upstream]
* Push tcg patch queue
* Posted v2 of ARMv8.2-FP16 fixes
[VIRT-243 # ARMv8.1-Atomic instructions ]
* Posted v3 of the patch set.
Passes the gcc testsuite.
[VIRT-198 # QEMU: SVE Emulation Support ]
* I now have a set of gcc testsuite failures
that are unequivocally SVE vector issues.
