Commit Message

Sandra Loosemore April 4, 2026, 4:05 p.m. UTC 
  The CX16 extension seems to have been omitted from the documentation
entries for a couple of early CPUs that supported it, which were
subsequently cut-and-pasted for newer models.  I checked the code
against the list of CPUs in the issue and found one more (novalake)
affected CPU that was added since then.

gcc/ChangeLog
	PR target/107337
	* doc/invoke.texi (x86 Options): Add CX16 feature to nocona,
	alderlake, arrowlake, arrowlake-s, pantherlake, novalake,
	bonnell, sierraforest, grandridge, clearwaterforest, and amdfam10
	family processors.
