re PR middle-end/39443 (Builtin redirection no longer working for memcmp)
PR middle-end/39443 * optabs.c (set_user_assembler_libfunc): New function. * expr.h (set_user_assembler_libfunc): New prototype. * c-common.c: Include libfuncs.h. (set_builtin_user_assembler_name): Call set_user_assembler_libfunc for memcmp, memset, memcpy, memmove and abort. * Makefile.in (c-common.o): Depend on libfuncs.h. * gcc.dg/pr39443.c: New test.
