Hi Madhu!

(As you've sent your equally worded
"GSoC'2023: Bypass assembler when generating LTO object files: GCC" email
to <gcc@gcc.gnu.org>, let me also Cc my reply here to that list, so that
others may contribute, too.)

Great, and welcome to GCC!  :-)

Building GCC and producing test results would be one obvious first task,
have you worked on that already?
<https://gcc.gnu.org/wiki/#Getting_Started_with_GCC_Development> has some
pointers to get started.  If you have specific questions, we're happy to
help, of course.

Then, get familiar with the basic concepts of code offloading in GCC.
<https://gcc.gnu.org/wiki/Offloading> is the best (only?) we have,
unfortunately, and it's somewhat out of date, so beware, sorry.  Looking
at existing libgomp plugins may help: 'libgomp/plugin/plugin-*.c', and
actually also the very simple 'libgomp/oacc-host.c'.  That's essentially
the API you need to care about (for OpenACC; but OpenMP 'target' also
won't require much more, for a start).

Make some thoughts (or actual experiments) about how we could
use/implement a separate host process for code offloading.

That wasn't attached to or referred to in your email?

Which specifically?
