PREFETCH_COMMENT :: ""+
	"The `prefetch_*` intrinsic are a hint to the code generator to insert a prefetch instruction if supported; otherwise, it is a no-op. Prefetches have no affect on the behaviour of the program but can change its performance characteristics.\n\n"+
	"The `locality` parameter must be a constant integer, and its temporal locality value ranges from `0` (no locality) to `3` (extremely local, keep in cache)."



VOLATILE_COMMENT :: ""+
	"Tells the optimizing backend of a compiler to not change the number of 'volatile' operations nor change their order of execution relative to other 'volatile' operations. "+
	"Optimizers are allowed to change the order of volatile operations relative to non-volatile operations.\n\n"+
	"NOTE: This has nothing to do with Java's 'volatile' and has no cross-thread synchronization behaviour. Use atomics if this behaviour is wanted."

NON_TEMPORAL_COMMENT :: ""+
	"Tells the code generator of a compiler that this operation is not expected to be reused in the cache. The code generator may select special instructions to save cache bandwidth (e.g. on x86, `movnt` instruct might be used)."
