This sinks the two stores in this example into a single store in cond_next. In this case, it allows elimination of the load as well: store double 0.000000e+00, double* @s.3060 %tmp3 = fcmp ogt double %tmp1, 5.000000e-01 ; <i1> [#uses=1] br i1 %tmp3, label %cond_true, label %cond_next cond_true: ; preds = %entry store double 1.000000e+00, double* @s.3060 br label %cond_next cond_next: ; preds = %entry, %cond_true %tmp6 = load double* @s.3060 ; <double> [#uses=1] This implements Transforms/InstCombine/store-merge.ll:test2 llvm-svn: 36040 |
