/* The machine-dependent file <bits/typesizes.h> defines __*_T_TYPE | |

macros for each of the OS types we define below. The definitions | |

of those macros must use the following macros for underlying types. | |

We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned | |

variants of each of the following integer types on this machine. | |

16 -- "natural" 16-bit type (always short) | |

32 -- "natural" 32-bit type (always int) | |

64 -- "natural" 64-bit type (long or long long) | |

LONG32 -- 32-bit type, traditionally long | |

QUAD -- 64-bit type, always long long | |

WORD -- natural type of __WORDSIZE bits (int or long) | |

LONGWORD -- type of __WORDSIZE bits, traditionally long | |

We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the | |

conventional uses of `long' or `long long' type modifiers match the | |

types we define, even when a less-adorned type would be the same size. | |

This matters for (somewhat) portably writing printf/scanf formats for | |

these types, where using the appropriate l or ll format modifiers can | |

make the typedefs and the formats match up across all GNU platforms. If | |

we used `long' when it's 64 bits where `long long' is expected, then the | |

compiler would warn about the formats not matching the argument types, | |

and the programmer changing them to shut up the compiler would break the | |

program's portability. | |

Here we assume what is presently the case in all the GCC configurations | |

we support: long long is always 64 bits, long is always word/address size, | |

and int is always 32 bits. */ | |
