developer-delphi-assembly-instructions

Delphi x86 assembly uses the built-in asm..end syntax, while NASM uses its own standard instruction format. This reference provides side-by-side examples for data transfer, arithmetic, logic, shifts, comparisons, and string operations to ensure correct syntax and cross-compatibility between both assemblers.

The instruction set reference covers x86 and x64 data transfer, arithmetic, logic, shifts, comparisons, control flow, and string operations. It provides concise syntax and semantic definitions for both Delphi's built-in assembler and NASM.

Yes, this assembly reference requires no external dependencies and is suitable for quick consultation during development and debugging of high-performance Delphi routines. You can jump directly to desired topics like MOV or Jcc and copy the exact syntax for your target assembler.

The best way to look up NASM and Delphi x64 assembly syntax is by referencing the in-file instruction set topics directly. You can jump to desired control flow or arithmetic instructions and copy the exact syntax for your target assembler during debugging.

Delphi's built-in assembler supports x86 string operations alongside NASM, with side-by-side snippets illustrating how the same operation is written in Delphi asm..end versus NASM. This ensures developers can verify correct instruction usage and cross-compatibility.
