ee_boot.s questions for MPC5644a
Posted: Mon Oct 03, 2016 3:57 am
Hi,Guys.I am pretty new to Erika OS. Lately, I'm reading source code of ee_boot.s, I notice there are some lines like "blt 1b" and "beq 2f". What are "1b" and "2f"? are those lable? or relative address offset? I search ee_boot.s over and over again and don't see any lable as "1b" or "2f".
My second question is also in this file "ee_boot.s", there are multiple instances of lable "1" , "2". Is this a special usage ? i read PowerPC assembly manual and find no similar usage.
Anyone can help me answer those questions?
Thanks a lot for your help!
