Given a module +and a function name, it extracts just the specified function from the +module, with a minimum of related cruft (global variables, function +prototypes, etc). + +This is useful because often something will die (for example SCCP +miscompiles one function of a large benchmark), and so you want to just +cut the testcase down to the one function that is being a problem. In +this case, 'extract' eliminates all of the extraneous global variables, +type information, and functions that aren't neccesary, giving you +something simpler. + +This is just an FYI, because I've found it useful and thought you guys +might as well. + |
