| /* 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. */ |
