/* Some machines may desire to change what optimizations are
performed for various optimization levels. This macro, if
defined, is executed once just after the optimization level is
determined and before the remainder of the command options have
been parsed. Values set in this macro are used as the default
values for the other command line options.
LEVEL is the optimization level specified; 2 if `-O2' is
specified, 1 if `-O' is specified, and 0 if neither is specified.
You should not use this macro to change options that are not
machine-specific. These should uniformly selected by the same
optimization level on all supported machines. Use this macro to
enable machbine-specific optimizations.
*Do not examine `write_symbols' in this macro!* The debugging
options are not supposed to alter the generated code.
