Series | [v3] y2038: Replace __clock_gettime with __clock_gettime64 | expand |
Dear All, > The __clock_gettime internal function is not supporting 64 bit time on > architectures with __WORDSIZE == 32 and __TIMESIZE != 64 (like e.g. > ARM 32 bit). > > The __clock_gettime64 function shall be used instead in the glibc > itself as it supports 64 bit time on those systems. > This patch does not bring any changes to systems with __WORDSIZE == > 64 as for them the __clock_gettime64 is aliased to __clock_gettime (in > ./include/time.h).

I don't think it make sense for benchtests to define _ISMAC if it uses glibc internal interfaces. Andreas.
* Andreas Schwab: > I don't think it make sense for benchtests to define _ISMAC if it uses > glibc internal interfaces. We have some internal interfaces that are available for !_ISOMAC, e.g. pretty much the entire support/ directory. I assume this is about <hp-timing.h>? We could decide that it should be in this category as well. Thanks, Florian

To be precise, it is sysdeps/generic/hp-timing.h: #define HP_TIMING_NOW(var) \ ({ \ struct __timespec64 tv; \ __clock_gettime64 (CLOCK_MONOTONIC, &tv); \ (var) = (tv.tv_nsec + UINT64_C(1000000000) * tv.tv_sec); \ })

Temporarily, until we have clock_gettime64 available outside glibc, too. Or would that be too awkward? Thanks, Florian
