[PATCH] D155524: [-Wunsafe-buffer-usage] Ignore the FixableGadgets that will not be fixed at an earlier stage

[Artem Dergachev via Phabricator via cfe-commits]

NoQ added inline comments.


================
Comment at: clang/lib/Analysis/UnsafeBufferUsage.cpp:1095-1102
   // Gadgets "claim" variables they're responsible for. Once this loop finishes,
   // the tracker will only track DREs that weren't claimed by any gadgets,
   // i.e. not understood by the analysis.
   for (const auto &G : CB.FixableGadgets) {
     for (const auto *DRE : G->getClaimedVarUseSites()) {
       CB.Tracker.claimUse(DRE);
     }
----------------
Let's also skip this part when there are no warning gadgets? Your initial patch was clearing the `FixableGadgets` list so it was naturally skipped, but now it's active again.
