Dan Gohman ce947366ec When complicated expressions are broken down into subexpressions ... with multiplication by constants distributed through, occasionally those subexpressions can include both x and -x. For now, if this condition is discovered within LSR, just prune such cases away, as they won't be profitable. This fixes a "zero allocated in a base register" assertion failure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96177 91177308-0d34-0410-b5e6-96231b3b80d8		2010-02-14 18:50:49 +00:00
