# REQUIRES: lld, target-windows

# Test that functions have the correct types.
# This uses the same input as SymbolFile/PDB/func-symbols.test. However, DIA 
# creates one named `Type` per function and uses identical UIDs for `Type` and
# `Function`, whereas native creates one unnamed type per signature and has different UIDs.
