I'm currently using Windows Notepad to program my Raspberry Pi in assembly language and I run it through 'as' and 'ld' to create the binary output. I would like to use an editor that has syntax highlighting specific to the version of ARM I'm using (in my case ARMv8) and don't mind paying but the IDE's I see out there such as Keil MDK, CodeWarrior, and others are a few thousand dollars and I'm not looking for all that extra functionality they provide. Is there anything out there, free or reasonably priced for the hobbyist, that can provide a more pleasant editing experience and has specific support for the ARMv8?
Okay, downloaded DS-5, it does have highlighting for Armv8!
