Hello, Before I start to write code to reinvent the wheel, I would like to know if there's something already out there to do context dependent expression simplification. What I need is to simplify an expression at a given point in a BB.
For example: bb2: r1 <- 2 if r2 != 0 goto bb3 else bb4 bb3: r3 <- r2 << 1 goto bb4 bb4: ... ... if ... goto bb4 else bb5 Is there any way already implemented to find the value of (and (plus r1 r3) (const_int 1)) at the end of bb4 and simplify it to (const_int 0)? Cheers, Paulo Matos
