Explicitly naming loop labels

Hello.

I was wondering if it is possible to explicitly attribute name to the 
labels that mark a loop entry.

By default, those are named something like ".L2".

What I would like is to be able to do something like

asm ("my_loop_label")
for(i=0...)

and the compilation would yield ARM assembly with that label name at the 
loop entry point.

Is something like that possible?

If not, do you happen to know a way to detect loops in ARM assembly?

Thank you.
