- Bcc:
Hi
I am looking for the source code related to linking stage--coz I am trying
to modify (very slightly) the linker. I understand that 'ld' is the linker
in Linux. My question is:
Is 'ld' a part of gcc toolchain?
--If it is, I should be able to find source file producing 'ld'. But I
haven't found the source file to be compiled to 'ld'.
--If it's not, main() of gcc.c should invoke ld if it found the '-o' option.
But I didn't find the invocation either(maybe it's not a straightforward
invocation).
Can someone show me where should I start to investigate it? Thanks a lot,
Shuo
Here is something I thought related, but I think it is not directly related
to linking stage.
6615 if (! strcmp (linker_name_spec, "collect2"))
6616 {
6617 char *s = find_a_file (&exec_prefixes, "collect2", X_OK, 0);
6618 if (s == NULL)
6619 linker_name_spec = "ld";
6620 }
