Subject: If a function is external, do not output a FunctionBlock for the function
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=86c936576150295078ce1e468d8800e6d62614e0;p=oota-llvm.git

If a function is external, do not output a FunctionBlock for the function
AT ALL.  This saves 11 bytes per external function from the bytecode file,
and is also required to make GhostLinkage work.
