Features:

• All GCC 9.2 features, plus latest mainline features.

Known Changes and Issues:

• Doing IPA on CMSE generates a linker error:
  The linker will error out when resulting object file contains a symbol for the clone function with the __acle_se prefix that has a non-local binding. Issue occurs when compiling binaries for M-profile Secure Extensions where the compiler may decide to clone a function with the cmse_nonsecure_entry attribute. Although cloning nonsecure entry functions is legal, as long as the clone is only used inside the secure application, the clone function itself should not be seen as a secure entry point and so it should not have the __acle_se prefix. A possible work around for this is to add a ‘noclone’ attribute to functions with the ‘cmse_nonsecure_entry’. This will prevent GCC from cloning such functions.

GNU Arm embedded toolchain for Windows

The GNU Embedded Toolchain for Arm is a ready-to-use, open source suite of tools for C, C++ and Assembly programming targeting Arm Cortex-M and Cortex-R family of processors. It includes the GNU Compiler (GCC) and is available free of charge directly from Arm for embedded software development on Windows, Linux and macOS operating systems.

This repository is the original Windows version of the GNU Compiler from Arm packaged for Visual Studio Code:

Install

In Visual Studio Code goto extensions (Shift+Ctrl+X), search for ‘metalcode-eu‘ and install the extension that is suited for your operating system.

The extension has four paths for the toolchain. You can use this in the tasks.json.

• arm-none-eabi.bin
• arm-none-eabi.include
• arm-none-eabi.lib
• arm-none-eabi.libgcc

Here is an example of tasks.json for GNU make.

With the following makefile:

Release Notes

Version 0.1.6

Version 8-2018-q4-major for Windows
Released: December 20, 2018

Version 0.1.2

Fixed typo in path to repository causing a wrong link in the marketplace.

Added a path to the libgcc files.

When you do bare metal development, you often exclude all standard libraries but you still need libgcc.a for integer division etc. The path to this file contains a version number that changes with every release of the toolchain. Using this variable you do not need to update your makefiles with every new release of the toolchain.

Version 0.1.0

Version 7-2018-q2-update for Windows

Version 0.0.5

Operating system specific PATH environment variable.

Version 0.0.2

Version 0.0.1
