Table 3-6 explains the possible values for
Example:
3.6.2 Return Value
In generating a signature symbol for a call to a function defined as returning a (non-void) value, if the
return value is ignored by the caller, then the compiler may specify
function.
3.6.3 Using Signature Symbols
The caller/callee match verification using signature symbols is implementation-dependent. The
implementation must accept object modules that do not contain signature symbols.
