<pre>While debugging <a href="https://github.com/CraneStation/wasi-sdk/issues/30">https://github.com/CraneStation/wasi-sdk/issues/30</a>, I had a
testcase that was linking in `__cxa_demangle`, and I wanted to know what was
pulling it in. The `--trace` option told me this:
/opt/wasi-sdk/share/sysroot/lib/wasm32-wasi/libc++abi.a: lazy definition of
__cxa_demangle
/opt/wasi-sdk/share/sysroot/lib/wasm32-wasi/libc++abi.a(cxa_demangle.cpp.o):
definition of __cxa_demangle
This doesn't actually indicate where the symbol is referenced from.
The answer turned out to be that it was referenced from
cxa_default_handlers.cpp.o in the same libc++abi.a file.
I can provide my lib++abi.a if that helps.</pre>
