Why arlo_reg into just adc & adcs? Why not adc_reg and adcs_reg (with equivalent changes for arlo_imm? Why is adr factored out of arlo_reg rather than arlo_imm? adr is an add immediate using the PC register as a base. Finally, please, please, please(!) generate your .md file diffs with gnu diff's '-F ^(define' option. This makes it *much* easier to identify which pattern is being modified.
