Log:
  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.

  A new pragma "GCC unroll" has been implemented in the C family of languages
  as well as Fortran to provide finer-grained control over loop unrolling.

  DWARF debugging information in the presence of link-time optimization now
  properly preserves language-specific information.  The -gcolumn-info
  option is now enabled by default, so column information is part of DWARF
  debugging information in addition to filenames and line numbers.

  The C family compilers have gained options -Wmultistatement-macros
  (warning about unsafe macros expanding to multiple statements used
  as a body of a statement such as if, else, while, switch, or for),
  -Wstringop-truncation (warning for calls to bounded string manipulation
  functions such as strncat, strncpy, and stpncpy that might either truncate
  the copied string or leave the destination unchanged), -Wcast-function-type
  (warning when a function pointer is cast to an incompatible function pointer,
  enabled by -Wextra), and -Wsizeof-pointer-div (warning for suspicious
  divisions of the size of a pointer by the size of the elements it points
  to, which usually is an indication of a mistaken way to calculate the
  number of elements in an array, enabled by -Wall), among others.

  The existing -Warray-bounds and -Wrestrict options have been enhanced to
  detect many more instances, as have -Wformat-overflow and
-Wformat-truncation.

  Error messages and warnings better highlight the locations of issues in
  many cases, and helpful "fix it" hints are provided more often.

  The C++ ABI (-fabi-version=12) introduces minor changes in a few fringe
  cases.  The GCC 7 ABI can still be selected with -fabi-version=11.

  The C++ frontend as well as libstdc++ feature experimental support for
  many C++2a features and Fortran has seen a large number of improvements.

  Lots and lots of improvements for Arm and AArch64 targets, as well as
  the usual dose on x86 and powerpc.
