I have recently been working on improving the performance of some VMS
FORTRAN programs. I have found some really interesting things (for instance:
in read(lu)(x(i),i=<st>,<end>) if st is an expression, the compiler
generates code for writing one element of x at a time. If st is a constant
or a single variable, the compiler generates code for one single write of the
appropriate size.).
If anyone has any other good info, I would sure apreciate hearing it:
it is a real pain to keep generating "machine" listings and looking at the
code.
Thanks,
john
