// Most of the types used in the prototypes are types from C, C++ or ObjC. There
// are a few builtin-specific types and qualifiers.
//
// builtin-specific types:
// - __builtin_va_list: This is the internal representation for va_lists
// - __builtin_va_list_ref: A reference-like type to __builtin_va_list
// - msint32_t: 'int' size if target is LP64, 'L' otherwise.
//
// builtin-specific qualifiers:
// - _Constant: Argument has to constant-fold to an integer constant expression

// __fp16 and __float128 builtin variants of libc/libm functions.
