Subject: Object, COFF: Don't consider AuxFunctionDefinition for getSymbolSize
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c4e8fb94df7bc4fdc2b5dfaeaa68f0838edfdb09;p=oota-llvm.git

Object, COFF: Don't consider AuxFunctionDefinition for getSymbolSize

mingw lies about the size of a function's AuxFunctionDefinition.  Ignore
the field and rely on our heuristic to determine the symbol's size.
