Comment (by Sebastian Huber):
The comment and pragma list is
{{{#!c
/*
* Ignore the following warnings from g++ and clang in the uses of
* _CONFIGURE_ASSERT_NOT_NULL() below:
*
* warning: the address of 'void Init()' will never be NULL [-Waddress]
*
* warning: comparison of function 'Init' not equal to a null pointer is
always
* true [-Wtautological-pointer-compare]
*/
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Waddress"
#pragma GCC diagnostic ignored "-Wpragmas"
#pragma GCC diagnostic ignored "-Wtautological-pointer-compare"
}}}
The name of the macro `_CONFIGURE_ASSERT_NOT_NULL` suggests that it
asserts that the parameter is not NULL. So, if you have a non-NULL
parameter, everything is fine. However, in this case you get the warnings.
So, these warnings are disabled by the pragmas. What is the problem?
