4. Instruction Sets

JWasm supports all instructions sets supported by Masm v8. These are

- the instructions implemented by 8086, 80186, 80286, 80386, 80486.

- the Pentium and Pentium Pro instructions.

- the MMX and K3D instruction set extensions.

- the SSE, SSE2, SSE3 and SSSE3 instruction set extensions.

- the Intel VMX instruction set extension ( since JWasm v2.09 ).

- the x86-64 64-bit instruction set ( implemented by ML64 ).

Additionally supported are

- SSE4.1 and SSE4.2 instruction sets ( since JWasm v2.01 ).

- AVX instruction set ( since JWasm v2.06 ).

With Masm, SSE4.1 and SSE4.2 require Masm v9; AVX requires Masm v10.
