...?? If you want to pass a value to a function that doesn't match the type, you will need to insert a cast instruction to cast the value to the correct type. Which cast instruction you insert will depend on the value's type and the type you want it to be.

Hello, I need create a CallInst to this function define i32 @function(i32 %n, i8 %m){ ... } I now how get argument's type but I do not know how to create arguments that meet these types. For example, if the argument is long, accurate pass CallInst an integer argument, however, if a Char, Char must pass an argument. How to get the type of the argument of the function definition and create the

We have a bitwidth analysis that can be downloaded. It is not in LLVM. There should be a link in the paper: http://www.cs.utah.edu/~regehr/papers/pldi075-cooprider.pdf John Regehr

Hi, LLVMers, has someone implemented bitwidth analysis for LLVM? I was looking for something similar to the bitwise compiler described in "Bidwidth analysis with application to silicon compilation, by Mark Stephenson, Jonathan Babb and Saman Amarasinghe" e.g.: http://portal.acm.org/citation.cfm?id=349299.349317 all the best, Fernando
