All,
During Connect the suggestion was made that each working group should have
its own IRC Channel for discussions and topics relating to the group in
particular (as opposed to #linaro which is 'generic' Linaro conversations).
Therefore I have just set up #linaro-tcwg on Freenode for the Toolchain
Working Group.
This channel is public and open to anyone who wants to talk with the TCWG
group about anything toolchain related.
Thanks,
Matt

Toolchain Working Group, Linaro
== Progress ==
o GCC dev. (7/10)
* Remote validation sanitizing:
- Implemented and tested a pure dejagnu fix (the actual
implementation works fine for GCC but might be an issue in a different
context, a cleaner fix almost done)
- Found a latent issue in GCC profiling test harness
* ARM and AArch64 backends LRA cleanup:
- Looked at the remaining artifacts, will prepare a patch for GCC 7
o Misc (3/10)
* Various meetings
* internal discussions

# Progress #
* Support range stepping on arm-linux. TCWG-518. [5/10]
Post patch series about "the thread is stepping over breakpoint but
it spawns child thread". The fix is OK but the test case changes are
being reviewed.
The more I test my range stepping patches, the more existing bugs I
find. Looking at the bug "software single step the instruction
branch to self."
* AArch64 linux syscall for record/replay. TCWG-532. [1/10]
Patch is out for review.
* Fix some ARM reverse debugging bugs. TCWG-183. [1/10]
Patch is pushed in. The original implementation wasn't carefully
reviewed, so I am sure there are bugs somewhere else.
* Patch review on arm tracepoint support. [1/10]
One patch is approved but I insist that another patch should be done
in generic part instead of ARM specific part, but the author wants do
it in ARM specific part because he things it is simpler.
* Misc [2/10]
** Go through the Linux kernel awareness GDB patches quickly, the first
reaction is "split your patch, please".
** Go to London to collect my passport.
# Plan #
* Support range stepping on arm-linux. TCWG-518.
* TCWG-167, TCWG-532.
* Prepare for the Linaro Connect travel.

Hi All,
Does linaro distributes arm-gcc as a pre-built static tool chain
distribution? If yes, where can i download them from. Please point me some
location from where i can download.
