Subject: 'bx lr' vs 'mov pc,lr'
Date: Mon, 14 Sep 2009 00:55:24 +0300 [thread overview]
Message-ID: <94a0d4530909131455x7a33cbaaw402642fb2e63c6d6@mail.gmail.com> (raw)
Hi,
I noticed that in 'arch/arm/lib/delay.S' we are using 'mov pc, lr'
instead of 'bx lr'. Why? It looks like 'mov pc, lr' is used all over
the place, but I can't find out what's the reason.
