I have never found them difficult to regenerate, but if you have only a non maintainer build, it is a pain to have to make a new maintainer build for a minor change.

Moreover, our m4 code is particularly painful to use and unreadable. I have been wondering for some time: should we switch to simpler Python scripts? It would also mean that we would have fewer files in the generated/ folder: right now, every time we add new combinations of types, we have a combinatorial explosion of files.

$ ls generated/sum_*
generated/sum_c10.c generated/sum_c17.c generated/sum_c8.c  generated/sum_i16.c generated/sum_i4.c  generated/sum_r10.c generated/sum_r17.c generated/sum_r8.c
generated/sum_c16.c generated/sum_c4.c  generated/sum_i1.c  generated/sum_i2.c  generated/sum_i8.c  generated/sum_r16.c generated/sum_r4.c

We could imagine having a single file for all sum intrinsics.

How do Fortran maintainers feel about that?
