x86 instruction set

recognized in the industry, you do not have to read the whole book thoroughly understand to contact reverse, crack and so on. My suggestion is "selective learning": need to compile programming development friends, naturally according to the book arranged in the order of the directory sequence of learning, but do not too much (a book is enough!) The rest depends on www.baidu.com. The goal is to software debugging, decryption, malicious code Analysis of Friends, recommended only to see "the first

The arm instruction set provides two instructions to directly control the status register (psr,program State Register). The Mrs Instruction is used to transmit the value of the CPSR or SPSR to a register; In contrast, the MSR transmits the contents of a register to CPSR or SPSR. These two instructions are combined to read/write to CPSR and SPSR.Cpsr_c represents

SSE instruction set The SSE (streaming SIMD extensions, single-instruction multi-data stream extension) Instruction Set was first launched by intel in the Pentium III processor. In fact, before piII was officially launched, Intel once published the so-called kni (Katmai new

Thumb Instruction Set The thumb command can be seen as a subset of arm commands in the form of compression. It is proposed for the code density [1] and has a 16-bit code density. Thumb is not a complete architecture and cannot expect the processing program to execute only thumb instructions rather than arm instruction sets. Therefore, the thumb command only need

Xcode instruction set, xcode Instruction Set Currently, ios provides the following instruction sets: I386: macArmv6: iPhone, iPhone E2, iPhone 3G, first generation and second generation iPod TouchArmv7: iPhone 3GS, iPhone 4, iPhone 4S, iPod 3G/4G/5G, iPad, iPad 2, iPad 3, iP

Some manuals are listed in http://blog.csdn.net/gengshenghong/article/details/7008682, where the Intel intrinsic Guide can query all intrinsic functions, Corresponding assembly instructions and how to use, etc., so, the next is not all analysis, the following only part of the analysis, so as to understand how to use these advanced instruction set in C + + code basic methods, as for more instructions to use,

Instruction Set Y86 Instruction Set Operator: addl, subl, andl, and xorl Jump character: JMP, jle, JL, je, JNE, jge, andjg Condition characters: cmovle, cmovl, cmove, cmovne, cmovge, and cmovg Others: Call, pushl, popl, halt Registers % Eax, % ECx, % edX, % EBX, % ESI, % EDI, % ESP, % EBP The stack pointer has % ESP.

All intrinsic functions, corresponding Assembly commands, and how to use these functions can be queried in the intrinsic guide. Therefore, we will not analyze them all in the following sections, to learn how to use these advanced instruction sets in C/C ++ code, the query manual is easy to understand as to how to use more commands. Note: The commands used below may only involve SSE instruction sets, rather

converting data into the MMX registers. SSE3 instruction Set A new 13 new instructions have been added to the SSE2,SSE3, which have previously been collectively referred to as PNI (Prescott new instructions). 13 instructions, one for video decoding, two for thread synchronization, and the remainder for complex mathematical operations, floating-point to integer conversions, and SIMD floating-point operati

program execution. There are two more familiar instruction sets: I386|x86_64 is the instruction set for Mac processors, and i386 is for Intel's Universal microprocessor 32 architecture. The x86_64 is a 64-bit processor for the x86 architecture. So when using the iOS emulator you will encounter the I386|x86_64,ios emul
