Re: The tale of -mrtd in GCC and Clang



Hi,

very interesting. Somewhere deep in my memory I have the idea that the mrtd option or rtd instruction was designed for Modula 2 which was modern at that time. It was probably pretty useless for a classical K&R c compiler that didn't even understand prototypes until 1989 or so... I assume GCC -mrtd predated c prototypes.
