== This week ==
- Completed merge of crypto backports 206128, 206130, 206131, 206132 and
206149 from trunk to Linaro 4.8 branch
- Out sick Friday
== Next week ==
- Build and test crypto backports
- Begin merging aarch64 crypto backport to Linaro 4.8 branch
== Future ==
== Progress ==
* Cbuildv2 fix for *_release() functions which were changing out of
the build directory but then not changing back to the builddir, which
caused problems with paths relative to the builddir. (1/10)
* TCWG-340 Enable Glibc remote testsuite integration - (7/10)
- Working with upstream community on scoping and designing remote
testsuite integration.
- Setting up arm chroot environment on chromebook with documentation
on how to make this reproduceable.
* TCWG-352 AArch64 clone is missing some CFI markup - (2/10)
- Setup aarch64 environment for testing and built static clone tests
to test the patch.
== Plan ==
* Start implementing (code) for glibc remote testsuite integration.
== Issues ==
None
== Progress ==
* Buildbots
- Odroid U2 died after a few days on USB stick, too. (I guess we're stuck
with Chromebooks)
- Upgrading chromebooks (to Saucy) due to a new GCC/libstdc++ 4.7+
restriction
- Shuffling chromebooks, we now have three buildbots:
- llvm-chrome-01: quick-build+check
- llvm-chrome-02: self-host+check
- llvm-chrome-03: test-suite
* MCJIT Remote
- Re-factored the communication protocol of MCJIT for remote processes
- Still seeing one random failure on ARM, investigating
* Compiler-rt
- Investigating how to get it compiling all libraries and sanitizers on ARM
* Background
- Patch reviews, especially IAS and EH
* Time
- CARD-862 8/10
- Others 2/10
== Plan ==
* Continue MCJIT and Compiler-RT investigations
* Continue reviewing IAS and EH patches
* Try to run the EH tests on the test-suite with the current changes
== Progress ==
* Add support for AArch32 ARMv8 VRINT to QEMU (4/10, TCWG-50)
* Add support for AArch32 ARMv8 VCVT to QEMU (4/10, TCWG-49)
* Add support for AArch32 ARMv8 16<->64bit VCVT to QEMU (1/10, TCWG-51)
* Fixed gas ARM VCVT encoding bug (1/10)
== Issues ==
* None
== Plan ==
* Complete outstanding QEMU work
* ARM setjmp/longjmp SystemTap probes
* malloc

Toolchain Working Group, Linaro
Hi,
I've been playing with linux-linaro-tracking and the 2013.12 (and
2013.10, 2013.11) toolchain release and when turning on the NEON in
kernel option I get:
CC lib/raid6/neon4.o
lib/raid6/neon4.c: In function 'raid6_neon4_gen_syndrome_real':
lib/raid6/neon4.c:113:1: internal compiler error: in
dwarf2out_frame_debug_adjust_cfa, at dwarf2cfi.c:1078
}
^
Use the attached .txt as .config and do 'make zImage' to replicate the
problem. You will probably need to attached patch as well since some of
the linaro patches break namespace support :(
regards,

== Progress ==
* ARM Process Record:
- Follow up on patches, almost all patches accepted. [0.5/10]
- Got GDB committ rights and set up git for pushing patches. [0.5/10]
* Spent time to read through fortran functions prologue to find a new fix
for TCWG-267. [1/10]
