Analyze elf Files:First write A. c file and compile it with Gcc-c xx.c-o XX.O.I am a elf_1.o file in this practice.Next enter Ls-l ELF_1.O to look for information on location files.The file information is then viewed in hexadecimal. Input: Hexdump-x ELF_1.OThe leftmost column of the displayed information represents a 16-binary representation of the offset address.View the specifications for Elf file header

the need for binutils certainly different, the above mentioned Gcc-core is dependent on binutils, Natural arm and X86 use of the Gcc-core package is not the same, glibc a C library, the end is in the form of libraries in the compiler, natural arm used by the GLIBC library and X86 is also different, and so on.Vi. ARM-LINUX-GCC and ARM-ELF-GCC:ARM-ELF-GCC, like ARM-LINUX-GCC, is also a cross-compiling softwa

1. BackgroundZephyr Project Flash and RAM space is tight, with very strong optimization requirements.The premise of optimization is to quantify the target, then how to quantify the amount of flash and RAM usage?After quantification, the quantification results are analyzed first, then the measures are taken to optimize the space.2. Flash/ram usage based on elf information and Linker.cmd analysisThe Linker.cmd file specifies whether different sections a

"Math Pocket Elf" the third spring plan----the first day ofProject Progress:Basic completion of a small game, the game has: randomly generated formulas, to determine the right and wrong function. 　　 Provides a good atmosphere for players with light background music and sound effects.

Because ECOs needs MIPS-elf-GCC to compile the kernel, the GCC compiler of the latest gcc4.4.1 version is compiled today. The steps are as follows: First, you must export the following variables before compiling: Export target = MIPS-elf Export prefix =/usr/local/$ Target Export Path = $ path: $ prefix/bin Echo $ Target Echo $ prefix Echo $ path ============================== Compiling environment: fc9 Th

An Analysis of the ELF File Format: Use NASM to generate an elf file as small as possible. Use the binary mode, the objdump mode, and the readelf mode to analyze the loading memory and running rules, and draw a conclusion. Edit a small ASM file as follows: crq@ $ cat new18.asmglobal _start_start: ud0 ud1 ud2 It is very simple. Only ud0, ud1, and ud2 commands are used to generate invali

In addition to the most common 3 paragraphs for. Text,. Data,. BSS, there are some other common segments, as follows: The. strtab:string table, which is used to store the various strings used in the ELF file. . symtab:symbol table symbol, from here you can make each symbol in the file. . Shstrtab: Is the name table of each segment, which is actually an array of strings consisting of the names of each segment. . Hash: symbolic hash table. . Line:

coloring code, insert a fence or refresh the cache to avoid conflicts or even allocate memory. All this means that two calls to the same API function may be performed at very different times (or even cross-frame), which makes it difficult to obtain the consistent frame time.Compared with the driver behavior on the PC, the modern console graphic api gives more control to the application. In these operations: When compilation occurs, when synchronizati

ELF Format notes (4) -- Section, elfsection The ELF file can contain many sections. All sections have a corresponding item in the section header table. Each section header is an Elf32_Shdr structure used to describe the information of the corresponding section. The e_shoff In the ELF Header specifies the byte offset of the section header table in the

In ARM-based embedded system development, there are two GCC tool chains that often use cross-Compilation:The main difference between ARM-Linux-* and arm-elf-* is that they use different C-library files. Arm-Linux-* useWhile arm-elf-* generally uses uclibc/UC-libc or RedHat for embedded systems.Newlib. glibc. Both uclibc, UC-libc, and newlib are C language library files.Glibc is developed for PC, and uclibc/

Under Linux, in addition to executable files, the target files (. o files) generated during compilation, dynamic link files (. so files), static link library files (. A files), and core dump files are stored in

The types of elf files under Linux are divided into the following categories:1, can relocate files, such as SIMPLESECTION.O;2, executable files, such as/bin/bash;3, share the target file, such as/lib/libc.so.In the Linux relocatable file elf structure article, we have analyzed the relocatable file elf structure.

The types of elf files under Linux are divided into the following ways: 1, can reposition files, such as SIMPLESECTION.O; 2, executable files, such as/bin/bash; 3, share the target file, such as/lib/libc.so. In the next article, we'll use OBJDUMP,READELF,HEXDUMP,NM to analyze a relocatable file simplesection.o in Linux. First attach SIMPLESECTION.C source code: int printf (const char* format, ...); int global_init_var = n; int Global_uninit_var;
