According to the ARM manual, it should be possible to access the banked registers for a specific CPU mode as, for instance, "r13_svc". When I try to do this gcc yells at me with the following error:

immediate expression requires a # prefix -- `mov r2,sp_svc'

What's wrong?

Why is this, and how can I get my file. makefile CC= /home/eclipse/ReidTest/cc/cross-toolchains/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-gcc… >>> More
