In this post, we will show a simple program which adds two numbers from two registers and save it into third register. So this program does following, Copy first number (ex. decimal 6) to register R0 Copy second number (ex.

Implementation details

decimal 3) to register R1 Add those two numbers from register R0 and R1 (6+3) and save the addition to register R2 (ex. decimal 9) So, the final program would look as, MOVS R0, #6 MOVS R1, #3 ADDS R2, R1, R0 Note: This instructions works for ARM.

Gotchas and common issues

  • Permission checks - verify user access rights and sudo privileges before executing system-level operations.

  • Environment configuration - double-check path variables and dependency versions to prevent runtime failures.

  • Backup safeguards - maintain configuration backups before applying system or database modifications.

Following these steps ensures clean configuration and reliable execution for assembly program to add two numbers.
