@MichaelEngel Not OP, but I'm also seeing this in the main() function of an executable that was compiled using CodeWarrior. It does the same thing as OP's function: the SP is copied to r31, and r31 is used as the SP in the rest of the function.

So it might help to specify which platform the code you are analyzing is supposed to run on. | |
