One further thought, why not init the reserved register in assembly and remove the gd relevant code in C? But that bears some risk if the register is changed and the assembly is forgotten to adapt..
No, I think this is to risky ...
It is absolutely not risky.
It is simply infeasible. :)
Different ARM toolchains use registers in different ways. Go from one toolchain to another, or from one *version* of a toolchain to another, and your "reserved" register is not any more.
