* very short week: off Monday/Tuesday
== Progress ==
* FDPIC
- uClibc-ng: patches committed upstream
- GCC: handling feedback on v2 patches
* GCC upstream validation:
- trunk build broken for a while on RHEL6 (gcc-4.4.7)
- fixed upstream just before I reported the problem
- my scripts now use gcc-5.4.0
* misc (conf-calls, meetings, emails, ....)
- book hotel/plane for GNU Cauldron and Connect
== Next ==
FDPIC:
- GCC: handle v2 patches feedback
- uclibc-ng: look at how to test fdpic mode with openadk
- Connect: prepare hacking room presentation
- GNU Cauldron 2018

+ finished testing and submitted for external review
* TCWG-1428 (Support arithmetic on FileCheck regex variable): address comments
+ continue to rework patch
* Regression testing of LLVM release process:
+ Add support to build from a branch (incl. trunk)
+ Make weekly regression testing from trunk
+ start enabling regression testing of Linaro LLVM release process
when scripts it use change
* Prepare for becoming a line manager next week
=== Plan for week 36 ===
* Welcome new starter

* Try to reproduce perf issue mentioned in week #30s weekly report on
latest perf
[VIRT-249 # SVE system mode emulation ]
Fixed a bug in last week's reorg, reported by Laurent.
Fixed a bug in our risu scripts for generating sve memory ops;
I was able to replicate Laurent's failure in risu, finally, and
then fix it. Still need to clean up the risu patch for submission.
[Upstream]
Reviewed mips mxu tcg patch set.
Reviewed s390 afp tcg patch set.

== This Week ==
* TCWG-1234: Hoisting and register pressure (4/10)
- Came up with another heuristic to avoid spill
- Verified it does not regress other test-cases (testsuite + private benchmarks)
* TCWG-319: Use vrecpe / vrecps to implement division (1/10)
- Rebased patch and validated it
- Seems like the issue of bad data alignment is also now seen with
armhf. Investigating
it further.
* PR83661 (2/10)
- Finished with patch prototype
* Public Holiday (2/10)
* Misc (1/10)
- Committed a typo fix in r263819
- Meetings
== Next Week ==
- Continue ongoing tasks
o LLVM
* Machine Outliner on ARM prototype:
- stack fixup support on-going
- test coverage in machine IR
* Buildbots babysitting
o Misc
* Jira gardening
* Various meetings and discussions.
[VIRT-198 # QEMU: SVE Emulation Support ]
Adjusted patch set based on Peter's review and upstreaming.
We talked about a method to initialize cpu config registers.
[Upstream]
Review:
nanomips round 11, now mostly pushed to master.
MPS2 patch set
raspi frame buffer patch set
Partway through a round 6 of the do_syscall split.
r~
Investigated yet another sanitizer related buildbot failure. This time
it looks like latent problems in the compiler-rt/cfi implementation
and tests provoked by the introduction of the Arm LLD bot.
- cfi requires LTO so it requires a bot using LLD or a bot configured
to run gold with the LTO plugin. Raised upstream PR on cfi.
[Linaro Connect]
Made some more progress on a clang-tool example to use for my
presentation on how to build a clang tool. Learned quite a bit more
about ast-matchers and the clang-ast.
[LLD]
Committed support for Armv5 and Armv6 in LLD.
[Miscellaneous]
Quite a heavy patch review week.
Planned absences:
On holiday on Tuesday
Progress:
* VIRT-65 [QEMU upstream maintainership]
+ put some reviewed MPS device patches into master, did a v2 of the
rest and sent them out again; these are now in master
+ ditto with patches for missing AArch32-Hyp features
+ code review:
- rth's patchset fixing float/int-with-scaling conversion
- rth's patchset adding system mode support for SVE
- linux-user: netlink fixes
+ sent out a patchset that wires up the GICv2 virtualization
memory regions and IRQs on the remaining boards that need it;
got this into master
thanks
