// Normally if we use a builtin function IWYU will ignore uses of it.
// However, if there is a mapping defined for that builtin then it should be
// respected.
// Clang considers the definition of a builtin to be at its first use, so we
// have two test cases:
// First test case for a builtin which was already used in a header we included
// IWYU: __builtin_expect is defined in...*which isn't directly #included.
int j = __builtin_expect(i, 0);
// Second test case for a first use of a builtin
// IWYU: __builtin_strlen is defined in...*which isn't directly #included.
int k = __builtin_strlen("");
