I think yes..

% gcc a.c -MF a.d -c -o a.o
cc1: error: to generate dependencies you must specify either -M or -MM
% clang a.c -MF a.d -c -o a.o
clang-9: warning: argument unused during compilation: '-MF a.d'
[-Wunused-command-line-argument]


% clang a.c -M -MF a.d -c -o a.o
# a.d generated
% gcc a.c -M -MF a.d -c -o a.o
# a.d generated
