Hello, I am experimenting with function reordering using PGO. I am looking at ordering functions based on the Last time of execution. For example, if the sequence of calls from profile feedback is: func1() -> func2() -> func3() -> func1()->func4() I would like the reordering in the binary as follows: func2 func3 func1 func4 The closest option I see is -fprofile-reorder-functions but it reorders based on the first time of execution. -fprofile-reorder-functions Function reordering based on profile instrumentation collects first time of execution of a function and orders these functions in ascending order. Is there any similar option that can help me achieve this? Thanks in advance.
