Hello,
in jit compilation mode I can call functions from the host binary by
using gcc_jit_context_new_call_through_ptr.
This doesn't work in AOT mode. Is there any way to include host
functions when compiling a binary in AOT mode?
GCC_JIT_OUTPUT_KIND_EXECUTABLE mentions that there is currently no
support for linking. I could see a work around where instead you
compile to GCC_JIT_OUTPUT_KIND_OBJECT_FILE and externally invoke gcc
to link your host/runtime and AOT-compiled functions together.
Cheers,
Stephan

Hi!
The docs are not updated since gcc_jit_context_add_driver_option() was
added in that section I believe.
You can link with anything with gcc_jit_context_add_driver_option().
E.g.
gcc_jit_context_add_driver_option(ctxt, "obj.o")
or
gcc_jit_context_add_driver_option(ctxt, "-L.")
gcc_jit_context_add_driver_option(ctxt, "-lwhatever")
Regards

Hi Petter,
Thanks! That's working great.
I'd update the docs but I am not really familiar with the gcc dev flow
so sombody else could probably do it a lot quicker.
Cheers,
Stephan
