For my bounds-checking in C, there are no syntactic changes to C.
But how efficient is it? Those research papers I mentioned reported
being able to get the execution overhead in Pascal down to something
like 5-10%.
Also somewhere around a 10% slowdown in this case, but this was with
dedicated ISA level support and various specialized helper instructions
(to check/set/adjust the pointer bounds bits).
Yeah, see, Pascal was able to do it without all that.
