// 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 (pow, round, etc) is a typical example.

// IWYU_ARGS: -I .

#include "tests/c/libbuiltins-direct.h"

float kapow(float x) {
  // IWYU: pow is...*math.h
  return pow(x, 2.0F);
}

/**** IWYU_SUMMARY
