Microsoft Contributes Windows On ARM64 "aarch64-w64-mingw32" Support To GCC 15

Microsoft engineers have contributed Windows On ARM64 support to the upstream GNU Compiler Collection (GCC) with the new "aarch64-w64-mingw32" target.

With GCC 14 released and GCC 15 in its early stage of development, one of the new targets to be introduced for this next compiler version is aarch64-w64-mingw32 for targeting Microsoft Windows on ARM64 platforms.

This support has been a long time coming as can be tracked via this Bugzilla ticket.

Microsoft engineers pulled everything together and as of a short time ago the aarch64-w64-mingw32 target is merged into GCC Git ahead of next year's GCC 15.1 stable release. The open-source LLVM/Clang compiler has already supported Windows on ARM while now the GNU compiler is joining the party too.
