Re: GNU ARM Assembler - no support for SRS and RFE instructions?

The GNU ARM assembler doesn't appear to support SRS and RFE which are
supported in ARM6 and higher I believe (I get "bad instruction"). I'm
using version 2.16.1 with the option -marm7tdmi when I assemble. Any
help would be greatly appreciated.

The ARM7 doesn't support these instructions. I guess you are
confusing ARM6 with ARMv6.

Wikipedia has a table showing which cores implement which revision of
the ARM architecture, e.g., the ARM7DTMI core implements the ARMv4T
architecture.

http://en.wikipedia.org/wiki/ARM_architecture#ARM_cores

According to that table, ARMv6 architecture is only used in the ARM11
and Cortex-M1 cores, so you won't get SRS and RFE instructions in an
ARM7DTMI.
