Generate a PEC (Portable Executable Code) binary.
This option puts the program intermediate representations in the object file and the binary. This binary may be used later for tuning and troubleshooting.
A binary built with -xpec is usually 5 to 10 times larger than if it is built without. The default is -xpec=no.
Without an argument, -xpec is equivalent to -xpec=yes.
