What did you do?

Trying to build plugin with the following code:
Go playground: https://go.dev/play/p/D0QJ0S09DX7?v=goprev

Ran go build -buildmode=plugin --ldflags '-s -w' -o plugin.so .

What did you expect to see?

Expect plugin.so to be built.

What did you see instead?

The following error:

go build -buildmode=plugin Output

Previously, the package attributesprocessor was being used in our main executable. We started seeing this error when we moved the code to build as a plugin.

Hmmm, I guess this may be due to that the external linker doesn't like certain characters in the symbol names. Previously only type symbols can contain weird characters, and we mangle them in plugin mode to avoid problems. With generics, function symbols can has well, because it contains the instantiation type, like the case above, which is probably instantiated this type https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/pkg/ottl/grammar.go#L26 , which does contain weird characters in the struct field tag.

I guess we may need to mangle more symbol names. Or, the compiler could drop at least the struct field tags from the shape name (which don't affect GC shape), probably field names as well.
