t = build_target_option_node (opts);
opts->x_ix86_arch_string = orig_arch_string;
opts->x_ix86_tune_string = orig_tune_string;
opts_set->x_ix86_fpmath = orig_fpmath_set;
/* Free up memory allocated to hold the strings */
for (i = 0; i < IX86_FUNCTION_SPECIFIC_MAX; i++)
free (option_strings[i]);
Indeed. We saved current options in build_target_option_node, where only
*pointers* to strings were saved. We should not free the memory, pointed by the
saved pointer.
