ax_cxx_restrict_this

Synopsis

AX_CXX_RESTRICT_THIS

Description

Determine whether the C++ compiler supports qualifying a member function with a restricted "this" pointer. Define "restrict_this" to the correct spelling; use like this:

  T::fn() restrict_this { /* code */ }

Otherwise, define "restrict_this" to be empty.

Note: the syntax above is a GCC extension. If your C++ compiler has a different way of applying the ’restricted’ qualifier to the "this" pointer, please consider reporting it.
