/* This file is compiled into assembly code which is then munged by a sed

script into two files: crti.s and crtn.s.
|
||||
|
||||
* crti.s puts a function prologue at the beginning of the .init and .fini
|
||||
sections and defines global symbols for those addresses, so they can be
|
||||
called as functions.
|

|

* crtn.s puts the corresponding function epilogues in the .init and .fini

sections.
|
||||
|
||||
This differs from what would be generated by the generic code in that
|
||||
we save and restore the GP within the function. In order for linker
|
||||
relaxation to work, the value in the GP register on exit from a function
|
||||
must be valid for the function entry point. Normally, a function is
|
||||
contained within one object file and this is not an issue, provided
|
||||
that the function reloads the gp after making any function calls.
|
||||
However, _init and _fini are constructed from pieces of many object
|
||||
files, all of which may have different GP values. So we must reload
|
||||
the GP value from crti.o in crtn.o. */
