/* There is a fair number of calling conventions that are in somewhat
wide use. The 68000/08/10 don't support an FPU, not even as a
coprocessor. All function return values are stored in %d0/%d1.
Structures are returned in a static buffer, a pointer to which is
returned in %d0. This means that functions returning a structure
are not re-entrant. To avoid this problem some systems use a
convention where the caller passes a pointer to a buffer in %a1
where the return values is to be stored. This convention is the
default, and is implemented in the function m68k_return_value.
The 68020/030/040/060 do support an FPU, either as a coprocessor
(68881/2) or built-in (68040/68060). That's why System V release 4
(SVR4) instroduces a new calling convention specified by the SVR4
psABI. Integer values are returned in %d0/%d1, pointer return
values in %a0 and floating values in %fp0. When calling functions
returning a structure the caller should pass a pointer to a buffer
for the return value in %a0. This convention is implemented in the
function m68k_svr4_return_value, and by appropriately setting the
struct_value_regnum member of `struct gdbarch_tdep'.
GNU/Linux returns values in the same way as SVR4 does, but uses %a1
for passing the structure return value buffer.
GCC can also generate code where small structures are returned in
%d0/%d1 instead of in memory by using -freg-struct-return. This is
the default on NetBSD a.out, OpenBSD and GNU/Linux and several
embedded systems. This convention is implemented by setting the
struct_return member of `struct gdbarch_tdep' to reg_struct_return. */
