This is off topic territory but as an example many early compilers generated

Gcc did not have this problem however and when I worked a bit with a play version of quake ported by Samuel Devulder on my 1200 in the 90's I recall that the generated assembly code was not too bad. It could be improved obviously but it was far from horrible. Samuel's "popt" peephole optimizer (on Aminet) managed to squeeze a few more cycles out of it but not an enormous amount.

Addendum: when I say "far from horrible" I'm not comparing to assembly experts output, but medium range assembly coders. Anyone can outclass a 68k on a few routines given enough time.
