/* 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. */ |
