2814 | ||
2815 | The target-specific code can define OPTION_DEFAULT_SPECS: | |
2816 | default command options in the form of spec macros for the | |
2817 | driver to expand (). | |
2818 | ||
2819 | For cc1 etc, the driver processes OPTION_DEFAULT_SPECS and, | |
2820 | if not overriden, injects the defaults as extra arguments to | |
2821 | cc1 etc. | |
2822 | For the jit case, we need to add these arguments here. The | |
2823 | input format (using the specs language) means that we have to run | |
2824 | part of the driver code here (driver_get_configure_time_options). | |
2825 | ||
2826 | To avoid running the spec-expansion code every time, we just do | |
2827 | it the first time (via a function-static flag), saving the result | |
2828 | into a function-static vec. | |
2829 | This flag and vec are global state (i.e. per-process). | |
