Relocation in generic ELF (Executable and Linkable Format) refers to the process of adjusting the addresses of symbols in an executable or shared object file during the linking phase. The relocation process is necessary because the final addresses of symbols are not known until the linking phase, and they may change depending on the memory layout of the program.
In ELF, relocations are represented by relocation entries in the relocation section of an object file. Each relocation entry contains information about a symbol that needs to be relocated and the type of relocation to be performed. The relocation types specify how the symbol's address should be adjusted, such as adding an offset or applying a specific calculation.
The EM:39190 mentioned in your question refers to the specific machine architecture or processor type for which the ELF file is intended. EM:39190 corresponds to the Hexagon processor architecture, which is commonly used in embedded systems and digital signal processors.
In summary, relocation in generic ELF involves adjusting symbol addresses during the linking phase, and EM:39190 represents the Hexagon processor architecture for which the ELF file is intended.
