@zygoloid, that is a fair question. My original intent had been to make the behavior contingent on driver mode. I switched to tying it to `-fms-compatibility` because other preprocessor behavior is contingent on that option and because that would be a less invasive change. Duplicate search path pruning is currently done by cc1 and I don't think that should be moved to the driver. I could be mistaken, but I don't think driver mode is exposed to cc1 (and that is probably a good thing). We could introduce a new cc1 option to opt-in to Microsoft style search path pruning. I'm not opposed to that. https://github.com/llvm/llvm-project/pull/105738 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
