[cxx-abi-dev] abi_tag mangling

[Richard Smith]

Thank you for writing this up!

If a type is not part of the regular mangling, and it contains an ABI tag
in its mangling but not as part of its type (for instance, a dependent
expression in a template argument references an entity with an ABI tag),
does that appear in the resulting mangling?

(That is, is an implementation required to effectively mangle the return
type and throw it away, or is some walk over the top-level type required
instead?)
