================ Comment at: clang/docs/LanguageExtensions.rst:2370-2398 +* ``bcmp`` * ``memchr`` -* ``memcmp`` (and its deprecated BSD / POSIX alias ``bcmp``) +* ``memcmp`` +* ``memcpy`` +* ``memmove`` +* ``memset`` +* ``strcat`` ---------------- aaron.ballman wrote: > Can you mention the deprecation issue here? Do we really provide constant evaluation support for all of these functions? ================ Comment at: clang/docs/LanguageExtensions.rst:2381 +* ``strcspn`` +* ``strerror`` * ``strlen`` ---------------- Do we really provide `__builtin_strerror`? I don't see it below. ================ Comment at: clang/docs/LanguageExtensions.rst:2425-2435 -Clang provides constant expression evaluation support for builtin forms of the -following functions from the C standard library headers -``<string.h>`` and ``<wchar.h>``: - -* ``memcpy`` -* ``memmove`` -* ``wmemcpy`` ---------------- You've moved this from the section where we describe the constant evaluation rules for these functions to a section where we describe the constant evaluation rules for string functions; those rules are quite different. ================ Comment at: clang/docs/LanguageExtensions.rst:2427-2428 +---------------- +Clang provides support for builtins forms of the following functions from the C +standard library header ``<ctype.h>``: + ---------------- We should say how these "builtin forms" are named and what they're for: that we provide a `__builtin_`-prefixed version of each of these functions that has the same signature and semantics as the function from the C standard library but doesn't require a header to be included.
