27// All of the extension source files have the same function name (_init). Since we don't support
28// per-file cflags that upstream uses, instead:
29//
30//  1. Rewrite the source files with filter_init to have per-file function names. (libext*_srcs)
31//  2. Create a new source file that defines a function (init_extensions*) with gen_init that calls
32//     all of the renamed _init functions (libext*_init)
33//
34// This all happens three times -- once each for libext, libext4, libext6
