3.4.154 -xpec[={yes|no}]

Generate a PEC (Portable Executable Code) binary.

PEC binaries may be used with Automatic Tuning System, ATS. More information about ATS is available at http://cooltools.sunsource.net/ats/index.html.

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.
