I have the following code: static inline void foo() __attribute((always_inline)); int a; static inline void foo() { a++; } int main(int argc, char *argv[]) { foo(); return 0; } However, the code generated by llvm 2.4 toolchain does not inline this function. opt retains the function call. Here is the output when I try to compile with -debug-only=inline:

I want to be able to do two things with LLVM (both just before code emission): 1. Insert a MachineBasicBlock just before a MachineBasicBlock. There is a function called AddPredecessor(). However, the comment says that it does not update the actual CFG. I want to redirect all CFG edges that are incoming to this MachineBasicBlock to the new one I create, and add just one outgoing edge (no branch)

Hello: I am new to llvm. I am looking for an example somewhere, or a walkthrough/guide on how to do runtime optimization using llvm. Ideally, I would like to: 1. Compile the program from C to LLVM or native with LLVM information embedded in the binary. 2. Run the binary under LLVM's interpreter, and profile the data. I hope LLVM has support for all this, and I don't have to insert my own

Hello: I am following the example code in BasicBlockPlacement.cpp. That transformation relies on basic block execution frequencies that have been read from a profile file. This is how it loads the profile data: 1. In getAnalysisUsage, it calls addRequired<ProfileInfo>(), and 2. In the runOnFunction, it calls getAnalysis<ProfileInfo>() which returns a ProfileInfo object pointer.

Hello: I have been able to successfully add a profiling pass to my PassManager. I now want to dump this profile information arbitrary (like maybe after 1 second of running the program). The problem is that the profile functions are in a separate library which is loaded dynamically. I cannot call: EdgeProfAtExitHandler(); directly because of linker problems (EdgeProfAtExitHandler() is
