[1] Source package snapshots are defined when the compiler is only
put through unit-testing and full validation is not performed.
[2] Stable source package releases are defined as releases where the
full Linaro Toolchain validation plan is executed.
~ Progress ~
* TCWG-1050, GDB 8.0 release. [4/10] Release branch is not created,
but test result
looks good.
** Fix PR 19942, patch v2 is OK. Need to fix some nits before check
in.
** Intel btrace python interface discussion. Good to see that Intel
people accept my suggested new interface, and finalize the details of
the new interface.
* TCWG-1040, Review SVE patches. [4/10]
The overall goal is to remove MAX_REGISTER_SIZE.
Reviewed some Alan's patches, and wrote two patches to remove
MAX_REGISTER_SIZE in frame.c and regcache.c.
* Misc, meeting, [2/10]
~ Plan ~
* More remote tests for GDB 8.0 release.
* SVE patches review, and start to think about GDB target description
changes for SVE.
* Public holiday on Friday and next Monday.

[TCWG-614] Long Range Thunks
- Posted for upstream review. I may have to do some refactoring of the
address allocation first to unify the linker-script and non
linker-script cases.
- Started work on a prototype that fabricates linker script commands
for the default non linker-script case. Failing 7 tests of 1007 and it
is a mess so some work to do here.
[TLS] Fixed recent breakage in ARM TLS caused by change in the way
that values are written to the GOT.
== Plans ==
Progress the prototype address allocation far enough to post upstream
for comment, I think that this is likely to take a few iterations to
get right.
