No objections from me. I would prefer there not to be a difference for assembly
at different optimisation levels.
I can't find any evidence that this affects Arm (Thumb to be precise) assembly
at all. For example:
```
.text
b dest // b.n 2-byte branch
b dest2 // b.w 4-byte branch
nop
dest:
nop
.space 2048
dest2:
nop
```
Regardless of what -mrelax-all is (or the llvm-mc equivalent) the first `b
dest` is always the smaller branch.
