I think one thing some early compilers did was read the source serially in one pass and write the output serially in one pass. If you were doing multiple passes you had do that for each pass. That means your compiler speed is IO bound. So one pass is faster. My cousins ex had a workflow in the late 70's that involved two floppy drives and a little dance to compile and link. Later he got a 5M hard drive which improved things a lot. |
