BRKPA

Break after first true condition, propagating from previous partition

If the last active element of the first source predicate is false then set the destination predicate to all-false. Otherwise sets destination predicate elements up to and including the first active and true source element to true, then sets subsequent elements to false. Inactive elements in the destination predicate register are set to zero. Does not set the condition flags.

if !HaveSVE() && !HaveSME() then UNDEFINED; constant integer esize = 8; integer g = UInt(Pg); integer n = UInt(Pn); integer m = UInt(Pm); integer d = UInt(Pd); boolean setflags = FALSE;
