== This Week ==
* LTO (7/10)
a) TCWG-548 (2/10)
- Fixed a minor bug in the patch
- Results of variable partitions with chromium: http://pastebin.com/fLD2JzgP
- Significant difference in size of last partition could probably
indicate sth wrong with
patch (all unpartitioned variables go to last partition).
b) TCWG-528 (3/10)
- Posted upstream after bootstrap+test passed on ppc64le-linux-gnu
- Addressed Richard's comments.
c) TCWG-299 (2/10)
- Firefox built on aarch64 natively (r1-a12) non LTO with gcc-5 branch
- Fails to build with trunk due to issues in firefox codebase (PR70722)
- Fails to build on armhf with following error: http://pastebin.com/9xydVtjj
* TCWG-72 (2/10)
- Rebased patch
- Addressed Ramana's comments
* Misc (1/10)
- Meetings
== This Week ==
- LTO: benchmark section anchors patch, submit patch for
increase_alignment upstream, firefox
- TCWG-72: Test and submit upstream
* Monday off [2/10]
# Progress #
* TCWG-468, ldr rt, =immediate
Have a feature complete implementation. Passes existing regression tests.
Still need to add more tests for new functionality and see if
implementation can be tidied up a bit
* Setting up a local chromebook to run the regression-tests. Should
now be able to run test suite on ARM relatively easily.
# Plan #
* Complete TCWG-468 and send upstream for review.
* Pick something else up.
* Monday off [2/10]
# Progress #
* TCWG-518, arm linux range stepping patches. [5/10]
Tried different ways to manage breakpoints, but the program still
gets SIGILL from time to time. Post my WIP patches upstream to see
if people have some ideas on this.
* TCWG-547, [1/10].
Try two approaches but give up due to the quite aggressive interface
changes. Fortunately, the change in the third approach is quite
small, testing the patch.
* Misc, meeting, [2/10]

* Public holiday (2/10)
== Plan ==
* Attend to pending stage1 patches
o 1 day off (2/10)
== Progress ==
o Extended validation (2/10)
* Extended validation now operational,
reporting enhancements investigations.
* Looked at gdb/guality unstable results.
* Reviewed some jobs.
o Linaro GCC (2/10)
* Scripted new Linaro development branch process.
o Upstream GCC (1/10)
* Digging in libatomic code.
o Misc (3/10)
* Various meetings and discussions.
== Plan ==
o 2 days off (Thu/Fri)
o Continue on validation and upstream work.
== This Week ==
* LTO (6/10)
a) TCWG-128 (1/10)
- committed patch for adding param lto-max-partition, which
can now be used as workaround for building chromium with minimal
number of required partitions.
- committed patch for setting default value of lto-min-partition to 10000.
b) TCWG-528 (1/10)
- Patch: http://people.linaro.org/~prathamesh.kulkarni/patch_increase_alignment.diff
- Cross tested on arm*-*-*, aarch64*-*-* and bootstrapped and tested
on aarch64-linux-gnu
- I want to cross test once for ppc64 since that's also affected.
c) TCWG-548 (4/10)
- Patch: http://people.linaro.org/~prathamesh.kulkarni/patch-vars-3.diff
- Cross tested for arm*-*-* and aarch64*-*-*
* TCWG-319 (2/10)
- Comparing diff's of vect for arm and armeb shows, armeb not
supporting unaligned access
- Looking thru arm backend code to see why this happens.
* Validation (1/10)
- Script to build chromium
* Misc (1/10)
- Looked at PR70848, PR60172
- Meetings
== Next Week ==
LTO: section anchors, increase_alignment pass
TCWG-319: Continue investigation
Validation: Try to get the script merged to tcwg-buildapp repo.
# Progress #
* TCWG-466, ADRL pseudo instruction support in integrated assembler. I
couldn't find a way of putting ADRL into the assembler in a
maintainable way. Managed to work out a pretty close approximation of
ADRL in a macro so I added it to upstream PR. Put the results of the
my investigations into TCWG-466. Agreed with Renato's initial
diagnosis of won't fix.
* TCWG-468, Transform LDR rn, =expr pseudo instruction into MOV. I'm
more hopeful with this one. I've got a prototype that delays the
emission of the constant pool entry to a point where the
transformation can occur.
* Try out the build and push scripts. Had a frustrating day of chasing
down missing dependencies from my Ubuntu 12.04 machine while building
lldb. Should be resolved now.
# Plan #
* UK national holiday on Monday.
* Continue with TCWG-468. I've got a tablegen prototype that treats
LDR rd,= as a real pseudo instruction. Need to finish Thumb and
Thumb2. Next step after that is to do the transformation to MOV.
* Will spend any other time investigating LLD
# Progress #
* TCWG-518, range stepping on arm-linux. Rebase my patches, and choose
a different approach which is better. However, GDBserver crashes in
some cases, and I am investigating the crash. [5/10]
* TCWG-547, make some progress on the upstream discussion. We agree to
do it in a cleaner way but some GDB internal interface needs some
changes. [2/10]
* Read some articles about exception handling, this one is quite useful,
https://gcc.gnu.org/ml/gcc/2002-07/msg00391.html [1/10]
* Meeting, upstream patch review. [2/10]

== Progress ==
* Rework LLVM helper scripts [TCWG-571] [4/10]
- Code review + minor improvements to the scripts
- Started a discussion about the interfaces of some of the scripts
(llvm-projs, llvm-sync)
* Inline assembly constraints support for ARM [TCWG-560] [3/10]
- More investigations for PR24071
- Discovered that the assert is only triggered for
aarch64-linux-gnueabi, whereas arm-linux-gnueabi behaves as expected
(prints the error but doesn't assert afterwards). This has proven
useful for figuring out the intended behavior of the code.
* Move buildbots to CMake 3.4.3 [TCWG-573] [1/10]
- Helped move some of the bots (llvm-a15-*) to CMake 3.4.3
* Misc [2/10]
- Buildbot monitoring
- Meetings
== Plan ==
* Inline assembly constraints support for ARM [TCWG-560]
- Come up with a fix for PR24071
* Rework LLVM helper scripts [TCWG-571]
- Start a review for the new interface to llvm-projs/llvm-sync, so
we can have some concrete support for further discussion
- Investigate git worktree and how it could be factored into our
scripts (llvm-projs, llvm-build)
* Move buildbots to CMake 3.4.3 [TCWG-573]
- Help with the llvm-chrome-* bots if necessary
* OOO on Monday
