In place in/out element

Careful.

 

I've had cases where I want my code to be portable and have had serious issues with "smart" compilers on Real-Time systems.  I ended going back and putting in a load of IPEs to get my performance back.

 

Not all of NIs compilers for different targets are created equal.  Just because it works like a dream on one target, doesn't mean it'll do the same on all.

Speaking of in place structures, is there much point cascading them (top) or is all data inside an in place structure automatically acted upon in place (bottom)?

 

As drawn, there is not much point of doing the upper version.  No need to do a meaningless index operation and incur the small but measurable performance hit of the IPES to do a simple replace.  If I am actually going to perform an index+do something+replace operation then I prefer the IPES.
