EF_ARM_SYMSARESORTED (0x04) Each subsection of the symbol table is sorted by symbol value
|

(see section 4.4.8, Symbol table order, below)
|

EF_ARM_DYNSYMSUSESEGIDX (0x8) Symbols in dynamic symbol tables that are defined in sections

included in program segment n have st_shndx = n + 1.
|

(see section 4.4.9, Dynamic symbol table entries, below).
|

EF_ARM_MAPSYMSFIRST (0x10) Mapping symbols precede other local symbols in the symbol table

EF_ARM_EABIMASK (0xFF000000)(current version is 0x02000000)

This masks an 8-bit version number, the version of the ARM
|

EABI to which this ELF file conforms. This EABI is version 2. A

value of 0 denotes unknown conformance.
