1/2/2023 0 Comments Iar create elf file![]() The size in bytes of one entry in the file's program header table. The SPARC flags are listed in the following table. Flag names take the form EF_machine _flag. Processor-specific flags associated with the file. If the file has no section header table, this member holds zero. The section header table's file offset in bytes. If the file has no program header table, this member holds zero. ![]() The program header table's file offset in bytes. If the file has no associated entry point, The virtual address to which the system first transfers control, thus starting the process. The value of EV_CURRENT changes as necessary to reflect the current version Extensions will create new versions with higher numbers. The value 1 signifies the original file format. Identifies the object file version, as listed in the following table. A flag named WIDGET for the EM_XYZ machine would be called EF_XYZ_WIDGET. For example, the flags defined in Table 7-5 use the prefix EF_. Processor-specific ELF names use the machine name to distinguish Other values are reserved and will be assigned to new machines as necessary (see sys/elf.h). Relevant architectures are listed in the following table. Specifies the required architecture for an individual file. Other values are reserved and will be assigned to new object file types as necessary. Values from ET_LOPROC through ET_HIPROC (inclusive)Īre reserved for processor-specific semantics. Table 7-3 ELF File IdentifiersĪlthough the core file contents are unspecified, type ET_CORE is reserved to mark the file. Identifies the object file type, as listed in the following table. Complete descriptions appear in "ELF Identification". The initial bytes mark the file as an object file and provide machine-independent data with which to decode and interpret the file'sĬontents. The elements of this structure are: e_ident ![]() The ELF header has the following structure, defined in sys/elf.h: #define EI_NIDENT 16 The treatment of missing information depends on context and will be specified if and when extensions are defined. ![]() Programs might therefore ignore extra information. If the object file format changes, a program can encounter control structures thatĪre larger or smaller than expected. Some object file control structures can grow because the ELF header contains their actual sizes. ![]()
