Hi.

It's quite obvious documentation patch does:
./xgcc -B. --help=target  2>&1 | grep mpri
  -mprioritize-restricted-insns=<0,2> Specify scheduling priority for dispatch slot restricted insns.

gcc/ChangeLog:

2018-04-10  Martin Liska  <mliska@suse.cz>

	* config/powerpcspe/powerpcspe.opt: Add IntegerRange.
	* config/rs6000/rs6000.opt: Likewise.

Showing this as a range is misleading, it's really more like an enum
(but not implemented that way).  And 1 is _higher_ priority than 2.

Ok, understood.
