AMD 64-Bit Technology 26568—Rev. 3.02—August 2002 DIVSD Divide Scalar Double-Precision Floating-Point Divides the double-precision floating-point value in the low-order quadword of the first source operand by the double-precision floating-point value in the low-order quadword of the second source operand and writes the result in the low-order quadword of the destination (first source). The high-order quadword of the destination is not modified. The first source/destination operand is an XMM register. The second source operand is another XMM register or 128-bit memory location. Mnemonic Opcode Description DIVSD xmm1, xmm2/mem64 F2 0F 5E /r Divides low-order double-precision floating-point value in an XMM register by the low-order double-precision floating-point value in another XMM register or in a 64- or 128-bit memory location. xmm1 xmm2/mem64 127 64 63 0 127 64 63 0 divide divsd.eps Related Instructions DIVPD, DIVPS, DIVSS rFLAGS Affected None MXCSR Flags Affected FZ RC PM UM OM ZM DM IM DAZ PE UE OE ZE DE IE M M M M M M 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 Note: A flag that can be set to one or zero is M (modified).

26568—Rev. 3.02—August 2002 AMD 64-Bit Technology Exceptions Exception Invalid opcode, #UD Real X Virtual 8086 Protected Cause of Exception X X The SSE2 instructions are not supported, as indicated by bit 26 of CPUID standard function 1. X X X The emulate bit (EM) of CR0 was set to 1. X X X The operating-system FXSAVE/FXRSTOR support bit (OSFXSR) of CR4 was cleared to 0. X X X There was an unmasked SIMD floating-point exception while CR4.OSXMMEXCPT = 0. See SIMD Floating-Point Exceptions, below, for details. Device not available, #NM X X X The task-switch bit (TS) of CR0 was set to 1. Stack, #SS X X X A memory address exceeded the stack segment limit or was non-canonical. General protection, #GP X X X A memory address exceeded a data segment limit or was non-canonical. X A null data segment was used to reference memory. Page fault, #PF X X A page fault resulted from the execution of the instruction. Alignment check, #AC X X An unaligned memory reference was performed while alignment checking was enabled. SIMD Floating-Point Exception, #XF Invalid-operation exception (IE) X X X There was an unmasked SIMD floating-point exception while CR4.OSXMMEXCPT = 1. See SIMD Floating-Point Exceptions, below, for details. SIMD Floating-Point Exceptions X X X X X X A source operand was an SNaN value. Zero was divided by zero. X X X ±infinity was divided by ±infinity. Overflow exception (OE) X X X A rounded result was too large to fit into the format of the destination operand. Underflow exception (UE) X X X A rounded result was too small to fit into the format of the destination operand. Denormalized-operand X X X A source operand was a denormal value. exception (DE) Zero-divide exception (ZE) X X X A non-zero number was divided by zero. Precision exception (PE) X X X A result could not be represented exactly in the destination format. DIVSD 109
