Bill Wendling e1196d6d3e Instcombine was illegally transforming -X/C into X/-C when either X or C ... overflowed on negation. This commit checks to make sure that neithe C nor X overflows. This requires that the RHS of X (a subtract instruction) be a constant integer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60275 91177308-0d34-0410-b5e6-96231b3b80d8		2008-11-30 03:42:12 +00:00
