From dd535f4f19ef2b5c367a362af445ecadcf45401e 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 (cherry picked from commit a4ed0471d71739928a0d0fa3258b3ff3b158e9b9) --- time/bits/types/time_t.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'time/bits/types/time_t.h') diff --git a/time/bits/types/time_t.h b/time/bits/types/time_t.h index 84d67f6ac3..00cde92c62 100644 --- a/time/bits/types/time_t.h +++ b/time/bits/types/time_t.h @@ -4,7 +4,7 @@ #include /* Returned by `time'. */ -#ifdef __USE_TIME_BITS64 +#ifdef __USE_TIME64_REDIRECTS typedef __time64_t time_t; #else typedef __time_t time_t; -- cgit 1.4.1
