Movss instruction
NettetMOVSS instruction when source and destination operands are XMM registers: DEST[31-0] SRC[31-0]; * DEST[127-32] remains unchanged *; MOVSS instruction when source operand is XMM register and destination operand is memory location: DEST SRC[31-0]; MOVSS instruction when source operand is memory location and destination operand … Nettet7. sep. 2024 · MOVSS xmm2/m32, xmm1 Move scalar single-precision floating-point value from xmm1 register to xmm2/m32. Now stores the 4 byte result from xmm0 [0:31] into [ebx+0x34], which we know is a single precision float from the result of the cvtpd2ps operation. So the result of this operation is a 32 bit float.

Nettet2. jul. 2024 · The MOVL instruction was generated because you put two int (i and j variables), MOVL will perform a MOV of 32 bits, and integer’ size is 32 bits. a non exhaustive list of all MOV* exist (like MOVD for doubleword or MOVQ for quadword) to allow to optimize your code and use the better expression to gain most time as … Nettet26. jan. 2024 · ByMartinJanuary 26, 2024 assembly – Why does this MOVSS instruction use RIP-relative addressing? RIPis the instruction pointer register, which means that it contains the address of the instruction immediately following the current instruction. n For example, consider the following code: n mov rax, [rip]nnopn n
Nettet25. nov. 2014 · Following the function prolog, a movss xmm0,real4 ptr [ebp+8] instruction (Move Scalar Single-Precision Floating-Point Value) copies the argument value a to the low-order 32 bits of register XMM0. The high-order bits of XMM0 are not modified by this instruction. The function uses another movss instruction to copy argument value b … Nettet26. aug. 2015 · movss [ecx+18],xmm0 That just moves the lowest quater of "xmm0" into " [ecx+18]". think of it as: {Q1} {Q2} {Q3} {Q4} {??} {??} {??} {??} each quater can have a max value of 32-bits. What "movss" does is it just moves the "Q1"; there's other instructions that move both Q1 and Q2 (64bits), or the whole thing (128bits).
Nettet23. aug. 2024 · And you can do movss in user space. Intel interrupt response is so slow it could be the case that an interrupt inserts an instruction in the current instruction stream way back at the instruction fetch stage. This may enable them to handle all the difficult cases more easily.
