Hi. I'm trying to ensure my complied code is optimal but the disassembly seems only part complete. Is there anyway to reveal the true compiled code or otherwise find the missing instructions?

eg. this asm

        // turn on H bits
        PORTA|= HA;
        PORTC|= HC;

Seems to be missing any IOR instructions in the disassembly

356:                   // turn on H bits
357:                   PORTA|= HA;
1030  504C     MOVF HA, W, ACCESS
358:                   PORTC|= HC;
1034  504D     MOVF HC, W, ACCESS

 

For some reason, it often happens. The command is there - at address 1032 - only they forgot to show it.

 

Are you saying this is incorrect?

Use the program memory view, it will have the complete disassembly. Look in the .LST (assembler listing) file that the compiler produced. The IDE has incomplete knowledge of what the compiler produces.

Get used to read the listing. It seems hard to do but no that much. It is very helpful.

 

Ok thx for the responses. I'll dig out the .lst file when I'm home tonight. This was one example but the disassembly seems to be missing about half of the required asm logic. I know it's there though because my circuit is working as intended.
