Line 281:
The most common architectures are in bold.
An example C struct declaration for the file header (from
struct ELF_fh {
Line 302:
short phdrcnt; // number of entries in section header or 0
short strsec; // section number that contains section name strings
};
=== Program header ===
Line 372:
Flags: 1 = executable, 2 = writable, 4 = readable.
An example C struct for the 32-bit (also from Levine) might be:
struct ELF_progh {
int type; // loadable code or data, dynamic linking info, etc.
int offset; // file offset of segment
int virtaddr; // virtual address to map segment
int physaddr; // physical address, not used
int filesize; // size of segment in file
int memsize; // size of segment in memory (bigger if contains BSS)
int flags; // Read, Write, Execute bits
int align; // required alignment, invariably hardware page size
};
=== Using the PIC with programs ===
