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 ).
- - 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.
