Update to the GCC 8.4 release which fixes at least 209 bugs compared
to the previous.

Multilib support on amd64 has been merged upstream, thus obsoleting
files/patch-amd64-gcc-multilib-support .

Update to the GCC 8.3 release which fixes more than 153 bugs compared to
the previous release, with a focus on regressions.

Pet portlint as it comes to the patch format of files/patch-fuse-ld=lld .

Update to the GCC 8.2 release, the second in the GCC 8 series.

This fixes more than 99 bugs, among others a performance regression
with -mtune=native on Intel Skylake chips has been fixed.

This also fixes a bug introduced in GCC 8.1 affecting passing or
returning of classes with a deleted copy constructor and defaulted
trivial move constructor (GCC bug c++/86094). GCC 8.2 introduces
-fabi-version=13 and makes it the default; ABI incompatibilities
between GCC 8.1 and 8.2 can be reported with -Wabi=12.

Welcome GCC 8.1, the first release of the GCC 8 series!

https://gcc.gnu.org/gcc-8/changes.html has a comprehensive overview of
many changes in this release and https://gcc.gnu.org/gcc-8/porting_to.html
addresses issues you may encounter porting to this new version.

To provide a brief overview of some of the more noticable changes:

On the optimization front inter-procedural optimizations (IPO) and profile
driven optimizations (PDO) have been further improved and some classic loop
nest optimization passes have been added: -floop-unroll-and-jam performs
outer loop unrolling and fusing of the inner loop copies, while
-floop-interchange exchanges loops in a loop nest to improve data locality.
These, as well as an improved -ftree-loop-distribution pass are enabled by
default at -O3 and above.
