; This test was originally for testing references to non-TU types from TUs, but
; it's currently too complicated to get that right reliably - non-TU types may
; have local linkage so declaring them in a TU is unreliable (consumers would
; have to be context-dependent to know which CU the TU is referenced from to
; know which type definition to match the declaration in the TU up to)

; Might as well keep the complex cases here in case we revisit this (with a flag
; on the type to indicate whether it should be in a type unit or not, distinct
; from the mangled name indicating whether the type has linkage or not perhaps
; (rather than checing the namespace scopes to see if any are internal (which
; doesn't handle the linkage of, say, a template instantiated with an internal
; type))

; Built from the following source, compiled with this command:
; $ clang++-tot decl.cpp -g -fdebug-types-section -c
; And modified (as noted in the comments) to produce some "simplified" and "mangled"
; simplified template names, to ensure they get template parameters in declarations
; created in type units.
