linker script in Clang?

Hi all,

I’m trying to use Clang to compile a C project. Unfortunately, it is heavily depend on the linker script. It has something like:

. = ALIGN(4);
FSymTab : {
__fsymtab_start = .;
__fsymtab_end = .;
. = ALIGN(4);

to get the _start and _end address of some section. Is there any equivalence in Clang? I searched on Google for a while bug failed to have an idea…
