What is the OPTION in the GCC's option "-Wl,OPTION"?

Question

When I read the GCC's info manual, I found the link option -Wl,OPTION:

`-Wl,OPTION'
 Pass OPTION as an option to the linker.  If OPTION contains
 commas, it is split into multiple options at the commas.

But I could not find the definition of the OPTION. Where can I find it?

Answer 1

The linker is called ld. Googling for ld options gives e.g. http://sourceware.org/binutils/docs-2.16/ld/Options.html

ho, I found: "if the linker is being invoked indirectly, via a compiler driver (e.g. gcc) then all the linker command line options should be prefixed by -Wl". Thanks. – Sean

Answer 2

It is linker options written like this (from my makefile):

FLAGS += -Wl,--enable-auto-import,--enable-runtime-pseudo-reloc

The linker options are listed in detail on the linker man page: ld (the GNU linker)
