an optimization

[Guy Laden <laden@math.tau.ac.il>]

Hi,

A recent thread in comp.compilers brought up the idea of compiling
RECORDS's into simple scalar variable.
This brings more opportunities for optimizations. eg: record elements can
be assigned to registers, potentially more dead-code can be found, etc...
Such an optimization should probably only be used when the RECORD as a whole
isnt needed (eg: its on the stack and isnt passed as a VAR parameter. record
assignment and nesting also needs thinking about)
It is my understanding that support for complex numbers in ooc is done
somewhat like this- Michael has mentioned that the backend will only see the
complex broken up into reals.
Perhaps it'd be worth considering implementing this optimization more
generally.

Guy.

just for the record, this post definitely doesnt mean
I'm for complex support in ooc ;-)
