Below is the full 8086/8088 instruction set of Intel (81 instructions total). [2] These instructions are also available in 32-bit mode, in which they operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts.
It supports Intel-style assembly language on the IA-32 and x86-64 computer architectures. It claims high speed, size optimizations, operating system (OS) portability, and macro abilities. [2] [3] It is a low-level assembler [3] and intentionally uses very few command-line options. It is free and open-source software.
x86 assembly language includes instructions for a stack-based floating-point unit (FPU). The FPU was an optional separate coprocessor for the 8086 through the 80386, it was an on-chip option for the 80486 series, and it is a standard feature in every Intel x86 CPU since the 80486, starting with the Pentium.
In the x86 assembly language, the TEST instruction performs a bitwise AND on two operands. The flags SF, ZF, PF are modified while the result of the AND is discarded. The OF and CF flags are set to 0, while AF flag is undefined. There are 9 different opcodes for the TEST instruction depending on the type and size of the operands. It can compare ...
A86 is an assembler for MS-DOS which generates 16-bit code for the Intel x86 family of microprocessors.Written by Eric Isaacson, it released as shareware in June 1986. The assembler is contained in one 32K executable and can directly produce a COM file or an object file for use with a standard linker.

He liked the tutorial on assembly programming and "excellent" sample code, but criticized the paucity of reference documentation. Noting that it was the only assembler that "cleanly assembled everything I fed to it", Blaszczak concluded that TASM was his favorite as it was "the best of both worlds: MASM compatibility without MASM's glitches ...
