== This week ==
* Linaro bugzilla 331 - [4.9 Regression] ICE in final_scan_insn, at
final.c:2952 [4/10]
- Triaged and investigating

emit-rtl.c:2019 [1/10]
- Unable to validate. Further investigation before closing
* TCWG-515 - Neon intrinsic bug testing [5/10]

tests from running

- Continue investigation into resolution for Linaro bugzilla 331
== Progress ==
* Fixed aarch64_be-none-elf builds and cross tests. (2/10)
* Forked ancient RSH support in DejaGnu to be more SSH aware. SSH
is now takes 1/4 of the time it used to for each remote execution test
case. (TCWG 512 - 4/10)
* Stabilized new ZSSH protocol in DejaGnu, also much faster than the
current RSH/SSH support. (TCWG 512 - 3/10)
* Meetings and Misc. (1/10)
== Plan ==
* Get my D01 board working finally, since I killed my Odroid U2.
* Review benchmarking patches.
* Do more thorough testing of SSH performance improvements.
== Progress ==
* TCWG-180 Debugging - LTO bootstrap failure in Aarch64 with GCC 4.9. (6/10)
Tried to recompile object files that showed differences in GCC trunk
on amd64 machine.It turned out that GCC make system always builds LTO
files in “gcc” directory and uses prev-gcc/xg++ to build them.
No differences when building stage2 and stage3 objects under same
directory “gcc” in FSF trunk.
Doing the same experiment with gcc 4.9 branch shows failure both in
x86_64 and aarch64.
Communicated the issue to Richard Beiner. Got some feedback on
debugging from Honza and Richard.
Tried passing –save-temps to BOOT_CFLAGS using FSF trunk, getting
assembler errors. Need to come back to this problem after finding root
cause.
Read about LTO passes and wpa (partitioned ) vs non portioned mode.
* Others (2/10)
* Upstream patch review.
* 1-1 Meeting Christophe.
* Misc and internal meeting.
* setup LLVM.
* Friday off (2/10).
== Plan ==
* Continue LTO bootstrap issue.
* Benchmark Core mark with LTO.
* Upstream patch review.
== MISC ==
* National holiday on 15th August .
== Progress ==

* Closed the card.
TCWG-413 - Release benchmarking (2/10)
