Sure, gfortran can be modified. The nontrivial part is that there are very few active contributors to gfortran. I suspect your patch would be much appreciated. Until then, you can modify your Makefile with very minor changes to stuff intermediate files into subdirectories. % ls Makefile a1.f90 b1.f90 c1.f90 d1.f90 % cat Makefile FC = gfortran11 PP = preprocessed/ FF = -c -cpp -save-temps -dumpdir ${PP} IN = f90 NAMES = a1 b1 c1 d1 all: mkdir -p ${PP} .for i in ${NAMES} ${FC} ${FF} $i.${IN} .endfor clean: @rm -rf ${PP} *.o % make mkdir -p preprocessed/ gfortran11 -c -cpp -save-temps -dumpdir preprocessed/ a1.f90 gfortran11 -c -cpp -save-temps -dumpdir preprocessed/ b1.f90 gfortran11 -c -cpp -save-temps -dumpdir preprocessed/ c1.f90 gfortran11 -c -cpp -save-temps -dumpdir preprocessed/ d1.f90 % ls Makefile a1.o b1.o c1.o d1.o a1.f90 b1.f90 c1.f90 d1.f90 preprocessed/ % ls preprocessed/ a1.f90 a1.s b1.f90 b1.s c1.f90 c1.s d1.f90 d1.s
