/* Initialize the record of emitted frame related registers. */
Don't use this macro to turn on various extra optimizations for
@option{-O}. That is what @code{OPTIMIZATION_OPTIONS} is for.

+If you need to do something whenever the optimization level is
+changed via the optimize attribute or pragma, see
+@code{TARGET_OVERRIDE_OPTIONS_AFTER_CHANGE}
@end defmac
+@deftypefn {Target Hook} void TARGET_OVERRIDE_OPTIONS_AFTER_CHANGE (void)
+This target function is similar to the macro @code{OVERRIDE_OPTIONS}
+but is called when the optimize level is changed via an attribute or
+pragma or when it is reset at the end of the code affected by the
+attribute or pragma. It is not called at the beginning of compilation
+when @code{OVERRIDE_OPTIONS} is called so if you want to perform these
+actions then, you should have @code{OVERRIDE_OPTIONS} call
+@code{TARGET_OVERRIDE_OPTIONS_AFTER_CHANGE}.
