--- Comment #3 from Wouter van Oortmerssen <aardappel at gmail.com> ---
Thanks for reporting, and figuring out the problem!

The point of MachineSymbolsUsed is that they are indeed all collected before
emitExternalDecls ever gets called, but that wasn't happening, because the pass
that does so, WebAssemblyMCLowerPrePass, was a FunctionPass which can get
scheduled interleaved with the AsmPrinter.

This patch changes it to a ModulePass to fix that:
