This feature request introduces a possibility to use a numeric displacement in a direct-relative addressing mode.
Previously, we could only use labels with direct-relative addressing mode in assembly, like
JUMP L_NAME. But it wasn't really convenient to add new labels just to implement simple two-lines loop or jump a few lines.Alternative way of defining direct-relative mnemonics
JUMP (IP+5)was shown in a bcomp manual, so I decided to implement it.Now, this mode supports both label reference and numeric displacement mnemonics.
Also, I wrote tests that cover conversions of assembly to instructions for all addressing modes.
