--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- Hm, but the COLLECT_GCC_OPTIONS variable is only used for communicating between the driver and the linker, the options therein are individually passed to the program execved? You are maybe looking for the -f*-map options to take a file as input containing multiple mappings?
