Hi Gabor,

The full example code and the generated assembly for GCC and for LLVM is in the Bugzilla issue.
I notice that this discussion seems focused around ARM-mode instructions. Is that intentional? In my experience everyone that actually cares about code size is using Thumb mode (mostly because they're on M-class CPUs).
It might be intentional, but I just wanted to make sure before a lot of effort was spent on marginal cases.
Cheers.
Tim.
