Hello,

In general, does version 4.x ARM generate better optimized smaller code than the older 2.x ARM Crossworks?

Regard,

Jim Norton

  Hi Jim,

  This is application dependent - you'll need to try it. The v4 software has options to select the clang compiler rather than gcc. The clang compiler sometimes does better (smaller/faster) sometimes worse (larger/slower) than gcc. Getting your code working with a couple of different compilers at varying levels of optimization (including optimize for size) is a good thing.

  Regards

  Michael
