== This Week ==
* TCWG-835 (2/10)
- Testing on SPEC CPU2006
- Found ICE while testing on spec unrelated to my patch, created
reduced test-case.
* TCWG-777 (2/10)
- Working on RTL pass - enhanced it so it only replicates insn when required.
- Prototype patch works for the test-case but ICE's during toolchain build.
- Trunk generates expected output for -O2, git-bisect shows from r226516
* TCWG-871 (1/10)
- Built for x86_64 non LTO
- Trying to cross compile for ARM
* Sick Leave (2/10)
* Public Holiday (2/10)
* Misc (1/10)
- Meetings
== Next Week ==
- Continue with TCWG-777, TCWG-835, TCWG-871
# Progress #
* TCWG-806, aarch64 remote debugging multi-arch
support. Patches are pushed in. Done. [2/10]
* TCWG-857, HW breakpoint/watchpoint in multi-arch. [3/10]
Both GDB and linux
kernel needs some fixes. Fix one bug in GDB. Read ARMv8 manual about
byte address select for thumb code (2-byte aligned instruction) and
the implementation in kernel.
* TCWG-757 some patches review, [1/10]
* Misc [4/10]
** ARM new starter training on Wed. afternoon and Thu.
** Read early-debug https://gcc.gnu.org/wiki/early-debug
# Plan #
* TCWG-857.
* Update the state of some old linaro tickets on GDB.

Hi,
I compiled the Linaro cross tool chain for arm v7 SOC and using the buildroot to create the images. When I use the downloaded precompiled tool chain from linaro releases, I am not facing any issues. But with compiled tool chain, multiple packages are failing with similar to below mentioned error. I tried building cross tool chain on both redhat and Ubuntu machines. When I see the difference of gcc -v, the cross compile is with "--host=x86_64-build_unknown-linux-gnu" and the pre compiled is with "--host=i686-build_pc-linux-gnu". I tried with "crosstool-ng-linaro-1.13.1-4.9-2014.08.tar.bz2" and "crosstool-ng-linaro-1.13.1-4.9-2014.09.tar.bz2".

Can somebody help me here.

Hi Linaro Toolchain Group,
I am trying to compiling cross aarch64-linux-gnu toolchain using local
directory (tar file) for gcc.
I am using file:/// as mentioned in the https://wiki.linaro.org/ABE.
../abe/abe.sh --target aarch64-linux-gnu --build all --release
20150819 --tarbin
gcc=file:///home/vpathak/arm/toolchain/build/snapshots/gcc-2015.11-5.tar.bz2
But I get following error:
ERROR (#146): get_URL (not supported for .tar.* files.)
ERROR (#533): get_source
(file:///home/vpathak/arm/toolchain/build/snapshots/gcc-2015.11-5.tar.bz2
not a valid sources.conf identifier.)
TRACE(#190): checkout ()
ERROR (#193): checkout (No URL given!)
ERROR (#161): checkout_all (Failed checkout out of gcc.)
Am I missing something ? How can we use a local directory (e.g. gcc
source code) for building toolchain using abe ?
Please help.
Thanks.
