The Linaro Toolchain Working Group (TCWG) is pleased to announce the 2017.11
snapshot of Linaro GCC 6 and 7 source packages.
o The GCC 7 series introduced an ABI change for ARM targets by fixing a bug
(present since GCC 5, see link below) that affects conformance to the procedure
call standard (AAPCS). The bug affects some C++ code where class objects are
passed by value to functions and could result in incorrect or inconsistent code
being generated. If the option -Wpsabi is enabled (on by default) the compiler
will emit a diagnostic note for code that might be affected by this ABI change.

[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.

- 6.4 and 7.2 ready to be deployed
o LLVM ramp-up
* Upstream BZ 32999:
- Struggled to construct the testcases which
produce the DAGs needed for a good coverage

# Progress #
* TCWG-1040, [6/10]
Update my patches to remove the last use of MAX_REGISTER_SIZE.
Post the whole patch series as an RFC. There are 15 patches, but I
rewrote them in seven times. This version is quite satisfying.
Targeting to GDB 8.2. One patch can't be merged until 8.1 is
branched.
* TCWG-1125, ARMv8 tagged address support in GDB.
Writing v3. [2/10]
* Misc, [2/10]
