This supersedes the init_array sysdeps directory. It allows us to check for ELF_INITFINI in both C and assembler code, and skip DT_INIT and DT_FINI processing completely on newer architectures. A new header file is needed because <dl-machine.h> is incompatible with assembler code. <sysdep.h> is compatible with assembler code, but it cannot be included in all assembler files because on some architectures, it redefines register names, and some assembler files conflict with that. <elf-initfini.h> is replicated for legacy architectures which need DT_INIT/DT_FINI support. New architectures follow the generic default and disable it.

/* Dummy crtn file.
|
|
|
|
In this configuration, crti.o and crtn.o are both empty because the
|
|
.init_array/.fini_array sections are used exclusively.
|
|
|
|
Older ports cannot use this because even if the linker used to
|
|
build libc itself has .init_array support, we don't want to produce
|
|
a crt[in].o that presume a linker that new will be used to link
|
|
other things later.
|
|
|
|
But new configurations without compatibility concerns for
|
|
toolchains without .init_array support can use this to avoid the
|
|
superfluous .init and .fini boilerplate code. */
