Is there any documentation or explanation of the Application Binary
Interface (ABI), or equivalent, when in native mode (non-PASE)?
I want to be able to determine how parameters are passed and where they
are located in memory when one C function calls another (a "static
procedure call", I believe) which would cover both intra-program calls
and inter-program (*PGM to *SVRPGM) calls.
The V5R3 ILE Concepts manual explains the use of call stacks which is
how it all appears to happen, but there doesn't seem to be a way to
access these directly from within C.
I'm using teraspace-enabled programs so pointers are 8-bytes rather
than 16-byte tagged pointers, if that matters.
