...nable-cxx11 However, I found that the clang++ did not build my project with the " -std=c++" option[1]. Could anyone kindly show me how to enable C++11 in a LLVM project, please? Thank you.

Nevertheless, I tried to enable it explicitly: $ ../configure --enable-targets=cbe It occurred the error: "*configure: error: Unrecognized target cbe*" Any clue?

The C Backend was remove in 3.1 (http://llvm.org/releases/3.1/docs/ReleaseNotes.html): "Major Changes and Removed Features ... The C backend has been removed.

It's supposed that we can iterate the instructions reversely and the first one who has attached metadata should be treated as the end of the function. Unfortunately, there is no reverse iterator of a function. Any idea?

Dear John, Now, I want to do dynamic analysis by dynamic slicing based on LLVM. I just see that you have implemented dynamic slicing for LLVM. I also check the Giri project, and I don't find the code. I hope I can learn something from your code. I am very appreciated if you can tell me how to get the code or send me one copy. Thank you very much! Pengfei -- View this message in context:

...deployment. The dynamic slicing can help a lot since the input is the key factor to locate errors. We have not a concrete plan for this project, but the dynamic slicing is heavily needed. Regards.

Hi, While looking over the IR generated by my source code, I came across the following: %arr = alloca [30 x i8], align 1 In the source code this particular line of code is represented by: int arr[30]; I was wondering how I could change the capacity of arr from 30 to any other integral value via a function-pass. I know that 'alloca' can be used for reserving space on stack; further,
