Attached is a file that contains sorted and uniq-ed runtime icall errors. We need to clean these up. Bug 1468382 tracks removing -fsanitize-cfi-icall-generalize-pointers which currently silences ~70 startup lines (which are _not_ included in the attached log). Bug 1465863 tracks fixing _in the correct way_ dynamically resolved cross-DSO calls. These errors _are_ included in the attached log. So to close out this bug we have the following options for each icall error we generate: 1: Allow it through without protection using the CFI blacklist (generally going to be our best option for third party code) 2: Allow it through using __attribute__((no_sanitize("cfi-icall"))) (this is ugly, better to use the blacklist) 3: If it's a dynamically-resolved cross-DSO call, develop a solution in/for Bug 1465863 and use it (this will be our preferred solution for Mozilla code, but as a stopgap we may choose to do Option 1 temporarily) 4: Fix whatever strange and potentially incorrect behavior we're doing (If it's Mozilla code and #3 doesn't apply, #4 should.) I believe the majority of our issues here are going to be dynamically resolved cross-DSO in third party code and we'll use Option 1.
