A.2.164 -xpec[={yes|no}]

Generates a Portable Executable Code (PEC) binary. PEC binaries can be used with the Automatic Tuning System (ATS) which works by rebuilding the compiled PEC binary for tuning and troubleshooting - the original source code is not required. More information about the ATS is available at http://cooltools.sunsource.net/ats/index.html.

A binary that is built with -xpecis usually five to ten times larger than if it is built without -xpec.

If you do not specify -xpec, the compiler sets it to -xpec=no. If you specify -xpec, but do not supply a flag, the compiler sets it to -xpec=yes.
