IIRC, it was a 53-pass compiler.
- Someone 2y ago63, according to the paper they wrote about it in 1965. https://ibm-1401.info/1401-IBM-Systems-Journal-FORTRAN.html https://ibm-1401.info/1401-IBM-Systems-Journal-FORTRAN.html: “The 1401 FORTRAN compiler has 63 phases, an average of 150 instructions per phase, and a maximum of 300 instructions in any phase.” The phases aren’t all what I would call a compilation phase, though. For example, phase zero: “Phase 00 - Snapshot. Loads a snapshot routine into 350 positions of core storage. This routine lists a specified amount of core storage.”
