C++ module scanning for named modules is now available, based on the format described in P1689R5, Format for describing dependencies of source files. The -fdeps-format=, -fdeps-file=, and -fdeps-target= flags may be used to generate dependency information. In GCC 14 p1689r5 is the only valid argument for -fdeps-format=.
