-Wc,-koenig_lookup,[on|off]

The -WC,-koenig_lookup option enables or disables standard argument-dependent

lookup rules (also known as Koenig lookup). It causes functions to be looked up in the

namespaces and classes associated with the types of the function-call argument. By

default, the option is enabled.

Example:

In the following example, if the option is not enabled, the call in main does not consider

declaration (1) and selects (2). With the option enabled, both declarations are seen, and

in this case overload resolution will select (1).

namespace N {

struct S {};

void f(S const&, int); // (1)

}

void f(N::S const&, long); // (2)

int main() {

N::S x;

f(x, 1);

}

Subprocesses of the Compiler

These options allow you to substitute your own processes in place of the default HP

aC++ subprocesses, or pass options to HP aC++ subprocesses.

-tx,name

The -tx,name option substitutes or inserts subprocess x, using name.

The parameter, x, is one or more identifiers indicating the subprocess or subprocesses.

The value of x can one or more of the following:
