From a4ed0471d71739928a0d0fa3258b3ff3b158e9b9 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Thu, 18 Jan 2024 10:18:01 -0300 Subject: Always define __USE_TIME_BITS64 when 64 bit time_t is used It was raised on libc-help [1] that some Linux kernel interfaces expect the libc to define __USE_TIME_BITS64 to indicate the time_t size for the kABI. Different than defined by the initial y2038 design document [2], the __USE_TIME_BITS64 is only defined for ABIs that support more than one time_t size (by defining the _TIME_BITS for each module). The 64 bit time_t redirects are now enabled using a different internal define (__USE_TIME64_REDIRECTS). There is no expected change in semantic or code generation. Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu, and arm-linux-gnueabi [1] https://sourceware.org/pipermail/libc-help/2024-January/006557.html [2] https://sourceware.org/glibc/wiki/Y2038ProofnessDesign Reviewed-by: DJ Delorie --- sysdeps/unix/sysv/linux/sys/epoll.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'sysdeps/unix/sysv/linux/sys/epoll.h') diff --git a/sysdeps/unix/sysv/linux/sys/epoll.h b/sysdeps/unix/sysv/linux/sys/epoll.h index 9b51e3bd14..fc8dce45c8 100644 --- a/sysdeps/unix/sysv/linux/sys/epoll.h +++ b/sysdeps/unix/sysv/linux/sys/epoll.h @@ -140,7 +140,7 @@ extern int epoll_pwait (int __epfd, struct epoll_event *__events, This function is a cancellation point and therefore not marked with __THROW. */ -#ifndef __USE_TIME_BITS64 +#ifndef __USE_TIME64_REDIRECTS extern int epoll_pwait2 (int __epfd, struct epoll_event *__events, int __maxevents, const struct timespec *__timeout, const __sigset_t *__ss) -- cgit 1.4.1
