<dd>This calling convention (the default if no other calling convention is

supports varargs function calls and tolerates some mismatch in the declared
prototype and implemented declaration of the function (as does normal C). For
integer arguments less than 32-bits, the value will be sign-extended to
32-bits before the call is made. If zero-extension is required, use the

<dd>This calling convention is exactly like the C calling convention except

integer arguments of less than 32-bits should be extended. A zero bit
indicates zero-extension while a 1-bit indicates sign-extension. The least
significant bit always corresponds to the return type of the function. The
bits in the <tt>bitmask</tt> are assigned to the integer parameters of the
function that are smaller than 32-bits. For example, a bitmask of value
5 (0b0101) indicates that the return value is to be sign extended, the first
small integer argument is to be zero extended and the second small integer
argument is to be sign extended.</dd>
