Code generators are are powerful enough to handle most complex addressing
modes in a locally optimal fashion.  However, if we're doing lots
of global optimization, the need for complex addresssing modes
doesn't arise (very often, when you've got enough registers, ...)

My small bet for the 90's is lots more work on using dependence
analysis for scalar machines, particularly managing memory
hierarchies.  Everybody who optimizes languages with arrays
is going to have to get into dependence analysis.

More work in software pipelining, interprocedural analysis and
optimization, pointer analysis???  Tools for writing parallel
and distributed code??  Minimizing TLB misses?
