Subject: When we resolve the type of an 'auto' variable, clear out the linkage
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ee18803f163c4ffcbc8f55a1aae48514d4f80521;p=clang

When we resolve the type of an 'auto' variable, clear out the linkage
of that variable; it will need to be recomputed with the resolved
type.
