@conservancy @theregister I read this as a German court requiring that not only must the GPL'ed code itself be handed over, but also the toolchains needed to build it.
That seems odd to me, especially if the GPL code uses toolchain components with a different license, or even a proprietary license, to generate.
Given that building toolchains often requires, potentially multiple, deeper levels of toolchains, one might begin to wonder how far this decision requires one to unravel the build system.
In theory this could mean that even the methods and masks to fab-build the chipsets for the underlying ARM or X86-64 processors must be handed over.
