From: Rich Felker Date: Tue, 17 Dec 2019 23:19:05 +0000 (-0500) Subject: signal to kernel headers that time_t is 64-bit X-Git-Tag: v1.2.0~54 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=f12bd8e05c8bb2c3e2b91d635887ec424ef8fbd9;p=oweals%2Fmusl.git signal to kernel headers that time_t is 64-bit linux/input.h and perhaps others use this macro to determine whether the userspace time_t is 64-bit when potentially defining types in terms of time_t and derived structures. the name __USE_TIME_BITS64 is unfortunate; it really should have been in the __UAPI namespace. but this is what was chosen back in v4.16 when first preparing input.h for time64 userspace, presumably based on expectations about what the glibc-internal features.h macro for time64 would be, and changing it now would just put a new minimum version requirement on kernel headers. the __USE_TIME_BITS64 macro is not intended as a public interface. it is purely an internal contract between libc and Linux uapi headers. --- diff --git a/include/alltypes.h.in b/include/alltypes.h.in index 94aa2089..d9ff462e 100644 --- a/include/alltypes.h.in +++ b/include/alltypes.h.in @@ -1,5 +1,6 @@ #define __LITTLE_ENDIAN 1234 #define __BIG_ENDIAN 4321 +#define __USE_TIME_BITS64 1 TYPEDEF unsigned _Addr size_t; TYPEDEF unsigned _Addr uintptr_t;
