Why does GCC14 matter when we are using a much older ARM cross compiler chain? Or is this an attempt to move the cross compile chain to a more recent version? |

Yeah exactly, this enables us to upgrade the compiler later. Also it's more semantically correct anyway, so it's a win-win |

Great, thank you for those changes! Are there any other change needed before we can upgrade the compiler?

No other changes I think. Been using GCC 14.2 locally without problems (14.3 out now but should be fine as well) |

One exception: newer compilers generate the linker warnings about the function stubs. These stubs are later removed by linker stripping as they're unused, but there's no way to disable the warning without either:
or we could just put up with them |
First commit fixes build for GCC 14
Second one adds nano specs to the compiler flags (needed as it sets compiler options) and uses nosys specs rather than linking manually. This made the group entries redundant also. Nice explanation of the spec files: https://metebalci.com/blog/demystifying-arm-gnu-toolchain-specs-nano-and-nosys/
