Delphi Arm64EC Native Compiler Toolchain
Target the next generation of Windows on Arm devices with your existing codebase
RAD Studio 13.1 and Delphi 13.1 introduce a new native target platform for the Delphi compiler: Windows on Arm. Delphi can now generate native Arm binaries that run on Windows Arm devices (including Windows on Arm virtual machines on Arm-based Macs), without relying on Intel emulation.

The new target is available in the IDE’s Platform Manager and allows developers to further expand their native Windows support, building applications for Win32, Win64 (Intel), and Win64 (Arm) from the same codebase. Existing Delphi applications can generally be recompiled for the new platform with minimal changes.

From a technical standpoint, Delphi generates Arm64EC binaries. Arm64EC (Emulation Compatible) is a Windows on Arm ABI introduced by Microsoft that enables native Arm64 code to interoperate seamlessly with emulated x64 code. This approach allows mixing Intel libraries with an Arm-based executable and supports incremental migration by preserving x64 calling conventions and register usage.
