== Issue ==
* none
== Progress ==
* [TCWG-762] - GCC Maintenance (9/10)
- PR65648 (ARMv6 IRA clobbering issue): Worked on a testcase that exhibit
the issue and don't conflict with various multilib configs.
Generic part of the
patch accepted, ARM related part needs to be reviewed by a ARM maintainer.
- PR65710 (LRA ICE in Thumb1): Proposed a quick workaround for this bug,
Proper fix was committed by Vlad.
- PR65729 (LRA ICE on arm-linux-gnueabhif): Proposed a fix, which is a stage1
material. Issue workarounded on trunk to avoid extensive
validation for the RC.
* [TCWG-702] Merge FSF 4.9 branch
- Merged up to revision 221939
- Will do another one to include needed LRA fixes.
* Misc (1/10)
- Various meetings
== Plan ==
- FSF branch merge #2
- Back on a Thumb2 insn fix
catomics - TCWG-436 [4/10]
* Fiddled with SPEC runs with unstripped binaries on tiny Juno discs
* Got a run for the interesting subset of SPEC, non-atomic catomics
still show no effect
* Tried a few catomics variations with the glibc malloc
microbenchmark, here non-atomic catomics show a significant effect
* Tried firing a perf shotgun at the malloc microbenchmark to see if
it suggests anything - results pending
Benchmark automation - TCWG-360 [3/10]
* Fixed Jira benchmarking
* Flushed some of the backlog out of my 'small fixups' branch
Misc [1/10]
Holiday [2/10]
catomics - TCWG-436 [4/10]
* Fiddled catomics to not use atomics at all, set off a new SPEC run
* Not using atomics seems wrong in general, but OK for malloc/free
Benchmark automation - TCWG-360 [1/10]
* Quick look at Tyler's LAVA console streamer
* Ported benchmark scripts to work on Debian
** Turns out there are two versions of netcat and Debian and Ubuntu
default to different ones
* Checked lab transition plan for benchmark-affecting points
Misc [1/10]
Holiday [4/10]
== Progress ==
* Public holiday (2/10)
* Sick (2/10)
* TCWG-620 (4/10)
- regression tested a version of patch
- few regressions lead to reworked it
- have a version that passes regression
* TCWG-753 and Bug 1373 (1/10)
- Al the Back-ports committed
- closing the card
* Misc (1/10)
- gcc-patchs and gcc-bugs list
== Plan ==
* Start with the RA issue during vectorization
* TCWG-521
== This Week ==
* TCWG-619
* V8
- aarch64 v8 LTO build with different options
- found workaround for v8 LTO build on ARM
* Chromium
- statically linking libstdc++ works for building chromium with
linaro-4.9-branch
- patched cp/typeck2.c to shut up on narrowing conversion errors to build
chromium with master branch.
- weird issue, chromium build hangs consistently at:
AR obj/components/libomnibox.a
due to patch to WebGLRenderingContextBase.idl, reverting that worked fine.
* PR49551
- git bisect shows ICE cannot be reproduced after r221297.
* Misc
- Preparatory Leave from college, semester ended.
== Issues ==
- ABE bugs: 1362, 1439, 665
- Can't access BlueJeans from Firefox on pc, gets stuck on
"Initialization" window.
== Next Week ==
- Complete LTO build v8 with different options on ARM, AArch64 and x86.
- Chromium LTO build on x86 with different LTO options.
- Chromium LTO and non LTO build on ARM.
- PR 49551.

# Progress #
* arm gdb test fail fixing. [4/10]
** TCWG-767, patch is committed.
** TCWG-769, patch is posted upstream for review.
** TCWG-765, triaged this issue. It is a test case or test harness
bug, rather GDB's. Need more time to investigate how to run "echo"
command on remote target through dejagnu.
** Fix a bug in my ARM displaced stepping code written in 2011.
** TCWG-509, patch is approved upstream, but will be combined into
other's patches.
** TCWG-567, Skip incorrect tests in gdb.base/watchpoint-reuse-slot.exp
for arm. Patch is committed.
* FSF GDB patch review. [3/10]
Test Pedro's "all-stop on top of non-stop" patch series on both arm
and aarch64. Some regressions are found and exchange thoughts on
them.
* meeting, [1/10]
# Plan #
* Test fails fixing for arm and aarch64 gdb.
* Upstream patches review.
