alexcrichton opened PR #13010 from alexcrichton:fix-winch-table-fill to bytecodealliance:main:

Note: this is a fix for GHSA-q49f-xg75-m9xw

This commit fixes a possible panic when a Winch-compiled module executes the table.fill instruction. Refactoring in #11254 updated Cranelift but forgot to update Winch meaning that Winch's indices were still using the module-level indices instead of the DefinedTableIndex space. This adds some tests and updates Winch's translation to use preexisting helpers.
