command subps destination, source
Subtracts the source from the destination. Used for Subtracting Packed-Single-Precision Floating-Point Values. The subps command can only be used with xmm registers.
Performs an SIMD subtract of the four packed single-precision floating-point values in the source operand (second operand) from the four packed single-precision floating-point values in the destination operand (first operand), and stores the packed single-precision floating-point results in the destination operand. The source operand can be an XMM register or a 128-bit memory location. The destination operand is an XMM register.
Command Parameters[edit]
| Parameter | Description |
|---|---|
| destination | xmm |
| source | xmm / m128 |
Examples[edit]
subps xmm0,xmm1
subps xmm3,[edx+110]
subps xmm15,[rdx+10]
subps xmm5,[00123abc]
subps xmm7,[UserDefinedSymbol]
