Enables recognition of mnenomics for the SIMD (single instruction, multiple data) instruction set extensions.
Syntax
.SIMDRemarks
If 686 mnemonics (or later) are not already being recognized, the .SIMD directive also causes an implicit .686 directive to be executed.
Issuing any .586 (or earlier) processor selection directive causes recognition of SIMD mnemonics to be disabled.
If SIMD mnemonics are being recognized, issuing a .686 (or later) processor selection directive does not cause recognition of SIMD mnemonics to be disabled. If this behavior is desired, use the .NOSIMD directive.
The .SIMD directive is not available in the M510, M600, M611, M612, or M613 emulation modes.
