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.
