So, its usually used by assembly ...Tue, 14 Apr 2026 07:12:00 GMThttps://stackoverflow.com/questions/6401586/intel-x86-opcode-referenceWhat is a relatively quick and easy method of looking up what an arbitrary opcode means (say, 0xC8) in x86? The Intel Software Developer's manual isn't very fun to search through...Tue, 14 Apr 2026 14:57:00 GMThttps://stackoverflow.com/questions/74557431/opcode-vs-operand-in-x86-assembly-source-codeThe opcode is the machine code representation of the instruction. Opcode can include the entire instruction's machine code or only the byte or bytes that select the instruction (possibly excluding prefixes, ModR/M, SIB, offset, immediate).Thu, 09 Apr 2026 14:27:00 GMThttps://stackoverflow.com/questions/15017659/how-to-read-the-intel-opcode-notation3.1.1.1 Opcode Column in the Instruction Summary Table (Instructions without VEX Prefix) The “Opcode” column in the table above shows the object code produced for each form of the instruction. When possible, codes are given as hexadecimal bytes in the same order in which they appear in memory. Definitions of entries other than hexadecimal bytes are as follows: • REX.W — Indicates the ...Mon, 13 Apr 2026 23:12:00 GMThttps://stackoverflow.com/questions/11028702/what-is-the-difference-between-machine-code-and-opcodeThe question is mostly related to PHP because IMHO opcode is mostly mentioned in PHP context. In fact Java is more popular for its byte-/opcode 1) Is opcode just a portion of machine code, does machine code consist of opcodes? Yes, but this opcodes are machine-dependent. The interesting thing in Java or PHP bytecode is that it's machine independent and runs in a platform-specific virtual ...Fri, 10 Apr 2026 04:03:00 GMThttps://stackoverflow.com/questions/511566/what-opcode-dispatch-strategies-are-used-in-efficient-interpretersgoto *opcode_targets[*next_instruction++]; opcode_targets maps the instruction in the language's bytecode to the location in memory of the opcode implementation. This is faster because the processor's branch predictor can make a different prediction for each bytecode, in contrast to a switch statement that has only one branch instruction.Thu, 09 Apr 2026 20:54:00 GMThttps://stackoverflow.com/questions/35381501/whats-the-difference-between-an-opcode-and-an-operatorWhy does the following operator overloading is ambiguous? What is the difference between machine code and opcode? Can different file extension executables be disassembled into the same instruction set OpCode? With operator overloading, how does the C# compiler decide which implementation applies with mixed-type operands?Thu, 02 Apr 2026 05:03:00 GMThttps://stackoverflow.com/questions/76331878/why-does-the-opcode-for-mov-from-a-segment-register-not-have-its-low-bit-set-itThe mov r/m, Sreg opcode you're looking at is 8C. The four opcodes with different values of its low 2 bits include mov Sreg, r/m, but also two unrelated opcodes that have the low bit set, and all exist only in forms with 16-bit operand-size so it doesn't really mean W for any of them. Although it does work for LEA and pop.Sun, 12 Apr 2026 02:56:00 GMThttps://stackoverflow.com/questions/76084999/getting-unknown-opcode-error-even-though-python-tf-versions-for-train-and-test-aGetting Unknown opcode error even though Python/TF versions for train and test are the same Asked 2 years, 11 months ago Modified 2 years, 6 months ago Viewed 917 timesSat, 11 Apr 2026 03:05:00 GMThttps://stackoverflow.com/questions/6081817/powerpc-opcode-tableI've found a fair amount of resources about programming in PowerPC assembly, but after quite some time looking, I haven't been able to find an instruction/opcode mapping table anywhere yet.Sun, 12 Apr 2026 23:06:00 GMT
