// Library builtins are, like normal builtins, compiled down to an intrinsic,
// but a header still needs to be included for the program to be valid. The math
// library (std::pow, std::round, etc) is a typical example.
// IWYU_ARGS: -I .
#include "tests/cxx/libbuiltins-direct.h"
float kapow(float x) {
// IWYU: std::pow is...*cmath
return std::pow(x, 2.0F);
}
/**** IWYU_SUMMARY
tests/cxx/libbuiltins.cc should add these lines:
#include <cmath>
tests/cxx/libbuiltins.cc should remove these lines:
- #include "tests/cxx/libbuiltins-direct.h" // lines XX-XX
The full include-list for tests/cxx/libbuiltins.cc:
#include <cmath> // for pow
