Pragma equivalent

None.

Specifies the maximum number of recursively instantiated template specializations that will be processed by the compiler.

-ftemplate-depth=256 or -qtemplatedepth=256

number: The maximum number of recursive template instantiations. The number can be a value between 1 and INT_MAX. If your code attempts to recursively instantiate more templates than number, compilation halts and an error message is issued. If you specify an invalid value, the default value of 256 is used.

Note that setting this option to a high value can potentially cause an out-of-memory error due to the complexity and amount of code generated.

None.

To allow the following code in myprogram.cpp to be compiled successfully:

template <int n> void foo() {
  foo<n-1>();
}

template <> void foo<0>() {}

   int main() {
   foo<400>();
}

Enter:

xlc++ myprogram.cpp -ftemplate-depth=400
