|
|
* This function is called for static executables, i.e. those that
|
|
* dont depend on shared libraries and are directly started by the
|
|
* Linux kernel.
|
|
*
|
|
* It takes the raw data block set up by the ELF loader
|
|
* in the kernel and parses it.
|
|
*
|
|
* The arguments are:
|
|
* elfdata -- The ELF loader data block; usually from the stack.
|
|
* Basically a pointer to argc.
|
|
*
|
|
* onexit -- Function to call on exit, can be NULL.
|
|
*
|
|
* slingshot -- Address of the program's main function
|
|
*
|
|
* structors -- Table of constructor functions arrays that must
|
|
* be called before the slingshot.
|
|
*
|
|
* It is called from the assembly fragment found in
|
|
* arch-$ARCH/bionic/crtbegin_static.S
