     Optimization selections make your program smaller or faster by
     eliminating unnecessary instructions and rearranging code.
 
     Option     Description
 
     ◄/Oa►      Specifies that aliases do not exist in your code;
                you must ensure that they do not
     ◄/Ow►      Specifies that aliases might occur across function
                calls
     ◄/Oc►      Enables block-level common subexpression optimization:
                allows the compiler to calculate the value of a common
                subexpression once (default)
     ◄/Og►      Enables global-level common subexpression optimization:
                allows the compiler to calculate the value of a common
                subexpression once
     ◄/Od►      Disables optimization
     ◄/Oe►      Disables register keyword and allows storage of
                frequently used variables and subexpressions in
                registers
     ◄/Ol►      Enables loop optimizations: allows moving or rewriting
                code so that it executes faster
     ◄/Op►      Improves floating point consistency; allows better
                tests for equality and inequality
     ◄/Or►      Enables single exit point from functions; useful when
                debugging with CodeView
     ◄/Os►      Minimizes executable file size
     ◄/O, /Ot►  Minimizes execution speed (default)
 
     Miscellaneous
 
     ◄/Ob<n>►   Controls inline expansion, where <n> is a digit from 0
                through 2
     ◄/Oi►      Generates intrinsic functions
     ◄/On►      Turns off potentially unsafe loop optimizations
     ◄/Oz►      Turns on potentially unsafe loop optimizations
     ◄/Oo[-]►   Turns on [or off] post code-generation optimizing
                (/Oi-, p-code default)
     ◄/Ox►      Maximizes optimization
 
     P-Code
 
     ◄/Oq►      Turns on p-code optimization
     ◄/Of[-]►   Turns on [or off] p-code quoting (default)
     ◄/Ov[-]►   Controls frame sorting (default)
 
     The letters following the /O, including the digits in b<n>, can
     appear in any order. When there is a conflict, the compiler uses
     the last /O option given. Each option applies to all source files
     following it on the command line.
 
     NOTE: If you are using the debugger, you may want to set the /Od
           option. If you don't specify /Od, some forms of the compiler
           perform optimizations that move code, possibly making it
           difficult for you to follow your program in the debugger.
