Description

This option enables the use of profiling information (including function splitting and function grouping) during optimization. It enables option -fnsplit (Linux) or /Qfnsplit (Windows).

This option instructs the compiler to produce a profile-optimized executable and it merges available profiling output files into a pgopti.dpi file.
