https://issues.dlang.org/show_bug.cgi?id=13517 Issue ID: 13517 Summary: Only touch .di generated file if changed Product: D Version: D2 Hardware: x86 OS: Mac OS X Status: NEW Severity: enhancement Priority: P1 Component: DMD Assignee: nobody puremagic.com Reporter: andrei erdani.com Running dmd -H always generates a fresh .di file, even if an existing .di file exists and has identical content. This confuses build tools - such as make and derivatives - that rely on file timestamp to assess what needs to be rebuilt. The compiler should generate the header in e.g. xyz.di.tmp file. Then, if xyz.di exists, compare the content of xyz.di with xyz.tmp. If they compare equal, remove xyz.di.tmp and otherwise rename it to xyz.tmp. --
