It is interesting to note that the Pascal compilers don't seem to be
as bad.  In a time-critical loop, I found that writing an explicit
array addressing calculation in MPW Pascal produced code only one
instruction away from my optimal assembler (a register transfer). I
promptly switched to using the Pascal, since it didn't have the
parameter passing overhead of the quasi-inline assembler inserter.

Can someone with MPW please dump and annotate the inefficencies
in the Pascal compiler, please? pretty please?
