/* Enable or disable target specific optimizations.
Not all targets have optimizations to enable.
Normally these optimizations are disabled by default but some targets
prefer to enable them by default. So this field is a tri-state variable.
The values are:
zero: Enable the optimizations (either from --relax being specified on
the command line or the backend's before_allocation emulation function.
positive: The user has requested that these optimizations be disabled.
(Via the --no-relax command line option).
negative: The optimizations are disabled. (Set when initializing the
args_type structure in ldmain.c:main. */
