Detailed Description

Rudimentary ELF loader and handling routines.

Function Documentation

obtains the error handling frame information form the elf image

Parameters

elfbase	virtual base address of the mapped elf
elfsize	size of the elf in bytes
eh_frame	returns the virtual address of the eh_frame
eh_frame_size	returns the size of the eh_frame
eh_frame_hdr	returns the virtual address of the eh_frame_hdr
eh_frame_hdr_size	returns the size of the eh_frame_hdr

Load ELF binary image into memory.

This function loads an ELF binary image, based at 'base' and of size 'size' into the memory provided by 'allocate'

Parameters

em_machine	ELF machine type.
allocate	Memory allocation function.
state	Pointer to state for allocation function.
base	Base address of ELF binary image in memory.
size	Size of ELF binary image in bytes.
retentry	Used to return entry point address
ret_tlsbase	Used to return TLS block base address
ret_tlssize	Used to return TLS block size
