#if __STDC_HOSTED__ && __has_include_next(<stdint.h>)

tl;dr: Teach Clang to work around g++ changing its workaround to glibc's
implementation of C99's attempt to control the C++ standard. *sigh*
The C99 standard says that certain macros in <stdint.h>, such as SIZE_MAX,
should not be defined when the header is included in C++ mode, unless
__STDC_LIMIT_MACROS and __STDC_CONSTANT_MACROS are defined. The C++11 standard
says "Thanks, but no thanks" and C11 removed this rule, but various C library
implementations (such as glibc) follow C99 anyway.
g++ prior to 4.8 worked around the C99 / glibc behavior by defining
__STDC_*_MACROS in <cstdint>, which was incorrect, because <stdint.h> is
supposed to provide these macros too. g++ 4.8 works around it by defining
__STDC_*_MACROS in its builtin <stdint.h> header.
This change makes Clang act like g++ 4.8 in this regard: our <stdint.h> now
countermands any attempt by the C library to implement the undesired C99 rules,
by defining the __STDC_*_MACROS first. Unlike g++, we do this even in C++98
mode, since that was the intent of the C++ committee, matches the behavior
required in C11, and matches our built-in implementation of <stdint.h>.

* C99 7.18.1.3 Fastest minimum-width integer types.
|
2009-11-12 16:08:27 +08:00
|
|
|
*
|
|
|
|
|
* The standard requires that exact-width type be defined for 8-, 16-, 32-, and
|
|
|
|
|
* 64-bit types if they are implemented. Other exact width types are optional.
|
|
|
|
|
* This implementation defines an exact-width types for every integer width
|
|
|
|
|
* that is represented in the standard integer types.
|
|
|
|
|
*
|
|
|
|
|
* The standard also requires minimum-width types be defined for 8-, 16-, 32-,
|
|
|
|
|
* and 64-bit widths regardless of whether there are corresponding exact-width
|
|
|
|
|
* types.
|
|
|
|
|
*
|
2011-04-15 13:22:18 +08:00
|
|
|
* To accommodate targets that are missing types that are exactly 8, 16, 32, or
|
2009-11-12 16:08:27 +08:00
|
|
|
* 64 bits wide, this implementation takes an approach of cascading
|
|
|
|
|
* redefintions, redefining __int_leastN_t to successively smaller exact-width
|
|
|
|
|
* types. It is therefore important that the types are defined in order of
|
|
|
|
|
* descending widths.
|
|
|
|
|
*
|
|
|
|
|
* We currently assume that the minimum-width types and the fastest
|
|
|
|
|
* minimum-width types are the same. This is allowed by the standard, but is
|
|
|
|
|
* suboptimal.
|
|
|
|
|
*
|
|
|
|
|
* In violation of the standard, some targets do not implement a type that is
|
|
|
|
|
* wide enough to represent all of the required widths (8-, 16-, 32-, 64-bit).
|
2011-04-15 13:22:18 +08:00
|
|
|
* To accommodate these targets, a required minimum-width type is only
|
2009-11-12 16:08:27 +08:00
|
|
|
* defined if there exists an exact-width type of equal or greater width.

|
2009-11-12 16:08:27 +08:00
|
|
|
*
|
|
|
|
|
* The standard requires that integer constant macros be defined for all the
|
|
|
|
|
* minimum-width types defined above. As 8-, 16-, 32-, and 64-bit minimum-width
|
|
|
|
|
* types are required, the corresponding integer constant macros are defined
|
|
|
|
|
* here. This implementation also defines minimum-width types for every other
|
|
|
|
|
* integer width that the target implements, so corresponding macros are
|
|
|
|
|
* defined below, too.
|
|
|
|
|
*
|
|
|
|
|
* These macros are defined using the same successive-shrinking approach as
|
|
|
|
|
* the type definitions above. It is likewise important that macros are defined
|
|
|
|
|
* in order of decending width.
|
2009-11-05 07:03:18 +08:00
|
|
|
*
|
|
|
|
|
* Note that C++ should not check __STDC_CONSTANT_MACROS here, contrary to the
|
|
|
|
|
* claims of the C standard (see C++ 18.3.1p2, [cstdint.syn]).
