This question is not appropriate for the mailing list gcc@gcc.gnu.org,
which is for the development of GCC itself. It would be appropriate
for gcc-help@gcc.gnu.org. Please take any followups to gcc-help.
Thanks.
The document you are looking for is generally called the ABI for the
target processor and operating system. There are different ABIs for
each processor, and different operating systems on each processor also
have different ABIs. If you tell us which specific processor and
operating system you are interested in we may be able to point you at
the ABI document for that target.
