Example 10. Moving a Function from Slow to Fast Memory at Run Time

* Define a section to be copied from load to run address
        .sect  ".fir"
        .label fir_src
fir:
*        < code here>      ;code for section

        .label fir_end

* Copy .fir section from load address to run address
        .text
   
        MOV    &fir_s,R11
        MOV    &fir_e,R12
        MOV    #fir,R13
LOOP:   CMP    R11,R12
        JL     Copy_Done
        MOV    @R11+,0(R13)
        INC    R13
        JMP    LOOP
Copy_Done:

* Jump to fir routine, now at run address

        JMP    fir

fir_s   .word  fir_src
fir_e   .word  fir_end
