   I have a problem that might be amenable to machine solution, can anyone advise me on practicality?

   I desire to have a usable, running copy of a very small compiler, for the PL/M-80 language. 1970s microcomputer stuff.

   I have access to the source code for the compiler, in an ancient FORTRAN dialect, and a binary of it that runs on an ancient OS (ISIS).

   From this I would like to produce a translation of the source code into C, specifically a pre-standard 1970s C or close enough for me to work with.

   Any suggestions?

     @aarbrk @tomjennings LLVM doesn't produces C, but using a Fortran compiler is probably easier, GCC also comes with one (gfortran) but doesn't seems to have full support for Fortran 77.

     @tomjennings Isn't it the case that “LLVM Flang” can compile Fortran into the “intermediate representation” from which LLVM produces C?Unless I misunderstand terribly.

     @lanodan @aarbrk

     My target host is an 8080. Fortran won't be directly useful. But I do have a very efficient c compiler for the 8080.

     I'm wanting to write 8080 (cp/m 80) tools natively in PL/M, not emulated.

     I have an alleged ISIS (old Intel OS) emulator/extension for CP/M that allegedly runs the ISIS PL/M compiler on CPM. I'm gonna try that but it sounds like a house of cards.
