Subject: Fix a compile crash building MultiSource/Applications/d with the new front-end.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c9a5ef524a9f461717bbf647b2d3da061aed720d;p=oota-llvm.git

Fix a compile crash building MultiSource/Applications/d with the new front-end.
The PPC backend was generating random shift counts in this case, due to an
uninitialized variable.
