@defmac DEFAULT_MAIN_RETURN
Define this macro if the target system expects every program's @code{main}
function to return a standard ``success'' value by default (if no other
value is explicitly returned).
The definition should be a C statement (sans semicolon) to generate the
appropriate rtl instructions. It is used only when compiling the end of
@code{main}.

@defmac INSN_SETS_ARE_DELAYED (@var{insn})
Define this macro as a C expression that is nonzero if it is safe for the
delay slot scheduler to place instructions in the delay slot of @var{insn},
