Never mind, I used ExecutionEngine's InstallLazyFunctionCreator and DisableSymbolSearching to cause malloc and free calls to be handled by my logging functions. Sorry for the unnecessary list mail. Is it possible to find out the size and beginning pointer of the current stack frame, from a function operating outside of the virtual machine, but called by a function within it? Thanks, Daniel

Hello, I'm writing a virtual machine that functions as a sandbox based on llvm. In order to prevent programs from accessing memory that has not been allocated to them, I want to replace calls to malloc and free with calls to a logged functions that will record the memory that is being allocated to the program. Is it possible to cast/convert a MallocInst or FreeInst to a CallInst? Thanks,
