Karthik Bhat b20d3957b6 Add support for cross block dse. ... This patch enables dead stroe elimination across basicblocks. Example: define void @test_02(i32 %N) { %1 = alloca i32 store i32 %N, i32* %1 store i32 10, i32* @x %2 = load i32, i32* %1 %3 = icmp ne i32 %2, 0 br i1 %3, label %4, label %5 ; <label>:4 store i32 5, i32* @x br label %7 ; <label>:5 %6 = load i32, i32* @x store i32 %6, i32* @y br label %7 ; <label>:7 store i32 15, i32* @x ret void } In the above example dead store "store i32 5, i32* @x" is now eliminated.
