WebFind changesets by keywords (author, files, the commit message), revision number or hash, or revset expression. WebCompact unwinding has a mode where it can fallback on DWARF CFI (X86, AArch64), and it is used for cases where the information can't be encoded in that format. I guess this can take a similar path. When CFI instructions are inserted in epilogue, wrong compact unwind encoding is generated.
