Section 14,92: global_optimization

 global optimization

 A level of optimization enabling code motion, strength reduction,
 split life analysis, instruction scheduling, and inlining of
 arithmetic functions.  Global optimization can be thought of as
 optimization within a program unit, that is, across statements.

 "Additional global optimization" is a level of optimization that
 improves speed at the cost of increasing the size of the VMS object
 module or U*X object file.  This optimization includes
 interprocedural analysis, inlining procedures, multiplication and
 division expansion, loop unrolling, and code replication.
 Additional global optimization can be thought of as optimization
 across program units.  See also optimization.
