This is a common pattern coming out of simplifycfg generating gross code. a: ; preds = %entry %sel = select i1 %cmp1, double %add, double 0.000000e+00 br label %b b: %cond5 = phi double [ %sel, %a ], [ %sub, %entry ] %cmp6 = fcmp oeq double %cond5, 0.000000e+00 br i1 %cmp6, label %if.then, label %if.end becomes a: br i1 %cmp1, label %b, label %if.then b: %cond5 = phi double [ %sub, %entry ], [ %add, %a ] %cmp6 = fcmp oeq double %cond5, 0.000000e+00 br i1 %cmp6, label %if.then, label %if.end Skipping block b completely if possible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187880 91177308-0d34-0410-b5e6-96231b3b80d8 |
