All tiers should compile with these scripts. But support will only be given if the OS vendor supports the platform.
For example, these tools should work on Windows XP but support will only be given to Windows 8.1 or newer. The same logic applies for macOS and Ubuntu.
| OS | Arch | Known to work on |
|---|---|---|
| Windows | x86_64 | Windows XP |
| Linux | x86_64 | Ubuntu 20.04 |
| Mac | x86_64 | macOS 10.9 |
| Mac | ARMv8 | macOS 11.0 |
Tier 2 is used for select targets on an as needed basis.
| OS | Arch | Known to work on | Note |
|---|---|---|---|
| Linux | i686 | Ubuntu 20.04 | Only for Raspberry Pi OS targets |
Tier 3 is not built in CI nor is tested, but bugs or merge requests will be addressed.
| OS | Arch | Known to work on |

| Linux | ARMv7 | Ubuntu 20.04 |
| Linux | ARMv8 | Ubuntu 20.04 |
| Architecture | Operating System | Version |

NOTE: Refer to the text in COPYING for the full legal statement. The text written
below is made from a very basic understanding of GPLv3 (and its exceptions).
As per GPLv3 (snippet below) all scripts to build the GNU toolchain must be provided under the same license. So, the scripts in the repository are released under GPLv3.
For an executable work, complete source code means [...], plus the scripts used to control compilation and installation of the executable.
The GCC exception still applies so the toolchain built with these scripts can still be used for any project as per the exception. A copy of this exception can be found here.
The files under patches/ are released under the same license as the project in which
it targets. As of April 2022, all projects are currently GPLv3 so the patches are also
released under GPLv3.
