Subject: [PATCH v1 13/13] Add aarch64-w64-mingw32 target to libgcc
Reuse MinGW definitions from i386 for libgcc. Move reused files to
libgcc/config/mingw folder.
libgcc/ChangeLog:
* config.host: Add aarch64-w64-mingw32 target. Adjust targets
after moving MinGW files.
* config/i386/t-gthr-win32: Moved to...
* config/mingw/t-gthr-win32: ...here.
* config/i386/t-mingw-pthread: Moved to...
* config/mingw/t-mingw-pthread: ...here.
* config/aarch64/t-no-eh: New file. EH is not yet implemented for
the target, and the default definition should be disabled.

This doesn't match the glob pattern you added to config.gcc in an earlier patch, but see my comment on that. The two should really be consistent with each other or you might get build failures late on.
R.
The target will be adjusted to aarch64-*-mingw* in config.gcc. This
change will ensure consistency with the target in libgcc.

Evgeny
