* Infrastructure:
- TCWG-1335: updated builder dockerfiles with postfix config. ABE
patch under review to send test results. Sent a patch for
contrib/test_summary script.
- Enabling use of Linaro binary release on old distro: unsuccessful
experiment with LD_PRELOAD so far.

== Next ==
* GCC/FDPIC
* GCC upstream validation
* Off on Friday afternoon.
# Progress #
* Fix non-gdbserver issue and GDB buildbot issue.
Intel people committed a patch breaks every non-x86 gdbserver. Test
with GDBserver is slowed down from 20~40 minutes to 6~12 hours.
The fix is pushed in,
requested upstream GDB buildbot maintainer to get rid of pending
builds until the fix.
# Plan #
* Review Alan H.'s patches.

- Meetings
- Slides
== Next Week ==
- Continue ongoing tasks.
Note: working for Linaro every other week
* start looking at fix for PR34170 / TCWG1137 (cannot select truncate in
ARMv7 backend):
+ inline asm with >=64bit floating-point output is not handled
+ wrote a tentative patch which crashes later in the code, need to
investigate
* Start slides for technical talk in TCWG room @ Linaro connect:
+ bswap done, started to refamiliarize myself with store merging pass and
its latest improvement
* Merge the two patches for TCWG-1308 (missing pseudo expansion + crash in
instruction selection of vector load/store with register writeback)
=== Plan for next Linaro week (week 10) ===
* finish fix for PR34170 / TCWG1137 (cannot select truncate in ARMv7
backend)
* finish slides for bswap/store merging passes presentation in hacker room
at Connect HK2018
* Off on Monday [1/5]
# Progress #

* Infrastructure:
- tcwg-buildapp + lava now triggered daily, to check lava/lab reliability.
- updated builder dockerfiles with postfix config. Patch under review
- some progress on enabling use of Linaro binary release on old
distro. My proposal was rejected, but the discussion moved forward.
- fixed toolchain build not to ship 'runtest' anymore, and moved
gdbserver from bin/ to sysroot dir

== Progress ==
* GCC
- FDPIC
- rebased GCC and GDB patches on top of recent master branches.
- adjusted some of the GDB (gdbserver) patches to cope with gcc-8
complaints.
- adjusted CI testsuite to cope with gcc-8
* GCC upstream validation:
- no regression to report this week :-)
- still checking go/libgo random results on some tests
* Infrastructure:
- improved tcwg-buildapp (Using Lava, thanks to Remi). Now retries
lava job several times if needed.
- managed to configure postfix to send emails from our build
containers (thanks Ben). Once this is properly configured/deployed,
we'll finally be able to send GCC validation results to the
appropriate list
- resurrected my old work to force use of the old memcpy version
such that our binary toolchains work on older distros (such as
RHEL6...)
* misc (conf-calls, meetings, emails, ....)
== Next ==
* GCC/FDPIC
* GCC upstream validation
== This Week ==
* Code hoisting (TCWG-1234) (6/10)
- Working on approach to add basic block info to ANTIC sets
* GCC bugs (3/10)
- Extend sincos to handle sin 2x (PR83661): Patch completed.
* Misc (1/10)
- Meetings
