/* 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. */

/* If we use the standard C version, the linkage table pointer won't
|
|
be properly preserved due to the splitting up of function prologues
|
|
and epilogues. Therefore we write these in assembly to make sure
|
|
they do the right thing.
|
|
|
|
Note that we cannot have a weak undefined __gmon_start__, because
|
|
that would require this to be PIC, and the linker is currently not
|
|
able to generate a proper procedure descriptor for _init. Sad but
|
|
true. Anyway, HPPA is one of those horrible architectures where
|
|
making the comparison and indirect call is quite expensive (see the
|
|
comment in sysdeps/generic/initfini.c). */
