I'm writing an application in which I want to obtain the code of a particular function during runtime. Obtaining the code of a function is not a problem, as I just used function pointer to obtain the start address of the function. However, I'm not able to determine the end of the function. I can solve this if I can obtain the size of the function and store it at a known memory location.
Is it possible to accomplish the above using:
1. ASSEMBLY: Use labels in assembly code to find the size of the function. 2. LINKER SCRIPT/SCATTER FILES: Use linker scripts or scatter files to find the size of the function.
Any help in this regard is highly appreciated.
Thanks, I'll look into .MAP file. Can you give some more details on how to do it in assembly?
