Subject: Correctly propagate the storage class to function template instantiations.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=459ef03126f9f0420efb3355e3b2ed3c1fdfb38a;p=clang

Correctly propagate the storage class to function template instantiations.

This fixes pr15753. This is another case of the fuzzy definition of the
"as written" storage class of an instantiation.
