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) --- io/ftw.h | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) (limited to 'io/ftw.h') diff --git a/io/ftw.h b/io/ftw.h index e4d1b84d53..39cf595b27 100644 --- a/io/ftw.h +++ b/io/ftw.h @@ -137,7 +137,7 @@ extern int ftw (const char *__dir, __ftw_func_t __func, int __descriptors) __nonnull ((1, 2)); #else # ifdef __REDIRECT -# ifndef __USE_TIME_BITS64 +# ifndef __USE_TIME64_REDIRECTS extern int __REDIRECT (ftw, (const char *__dir, __ftw_func_t __func, int __descriptors), ftw64) __nonnull ((1, 2)); # else @@ -146,7 +146,7 @@ extern int __REDIRECT (ftw, (const char *__dir, __ftw_func_t __func, __nonnull ((1, 2)); # endif # else -# ifndef __USE_TIME_BITS64 +# ifndef __USE_TIME64_REDIRECTS # define ftw ftw64 # else # define ftw __ftw64_time64 @@ -154,7 +154,7 @@ extern int __REDIRECT (ftw, (const char *__dir, __ftw_func_t __func, # endif #endif #ifdef __USE_LARGEFILE64 -# ifndef __USE_TIME_BITS64 +# ifndef __USE_TIME64_REDIRECTS extern int ftw64 (const char *__dir, __ftw64_func_t __func, int __descriptors) __nonnull ((1, 2)); # else @@ -180,7 +180,7 @@ extern int nftw (const char *__dir, __nftw_func_t __func, int __descriptors, int __flag) __nonnull ((1, 2)); # else # ifdef __REDIRECT -# ifndef __USE_TIME_BITS64 +# ifndef __USE_TIME64_REDIRECTS extern int __REDIRECT (nftw, (const char *__dir, __nftw_func_t __func, int __descriptors, int __flag), nftw64) __nonnull ((1, 2)); @@ -190,7 +190,7 @@ extern int __REDIRECT (nftw, (const char *__dir, __nftw_func_t __func, __nonnull ((1, 2)); # endif # else -# ifndef __USE_TIME_BITS64 +# ifndef __USE_TIME64_REDIRECTS # define nftw nftw64 # else # define nftw __nftw64_time64 @@ -198,7 +198,7 @@ extern int __REDIRECT (nftw, (const char *__dir, __nftw_func_t __func, # endif # endif # ifdef __USE_LARGEFILE64 -# ifndef __USE_TIME_BITS64 +# ifndef __USE_TIME64_REDIRECTS extern int nftw64 (const char *__dir, __nftw64_func_t __func, int __descriptors, int __flag) __nonnull ((1, 2)); # else -- cgit 1.4.1
