Wasmtime GitHub notifications bot (Dec 06 2020 at 02:09):cfallin opened PR #2482 from fix-indirect-br-branch-dest-accessor to main:
Found via fuzzing: the
branch_destination_mut()accessor on
InstructionDatawas missing a case forIndirectJump. As per the
doc-comment, this should returnNone. Note that thematchin
branch_destination()does haveIndirectJumpin the analogous place;
this appears to just have been an oversight.Adding an LICM test from the fuzzer (minimized) because this is how it
was triggered; it's somewhat difficult to write a more direct test than
this.<!--
