[PATCH] D99887: [lld][WebAssembly] Add `--export-if-defined`

[Derek Schuff via Phabricator via llvm-commits]

dschuff added a comment.

Pre-existing, but what does `--export` plus `--allow-undefined` do?



================
Comment at: lld/wasm/Driver.cpp:890
   // Handle the `--export <sym>` options
   // This works like --undefined but also exports the symbol if its found
+  for (auto &iter : config->exportedSymbols)
----------------
should this comment no longer say "if its found"? If it's not found, the whole process should error, right?
