Complete revert of 2019-08-19, st_atime in libc/include/sys/stat.h The revert-part of the revert-and-fix commit, b99887c4283f a.k.a. "Revert previous change to sys/stat.h and fix cris libgloss", apparently intending to revert f75aa6785151 a.k.a. "Fix regression in cris-elf caused by sys/stat.h change" and fix it in another way, wasn't complete. Although the fix-part added the prerequisite "#undef st_atime" (et al) to gensyscalls, the revert-part didn't revert the "&& !defined(__cris__)" in sys/stat.h, stopping st_atime (et al) from being defined. The effect of the unreverted change is that accessing the struct stat compatibility member names "st_atime" (et al) as in "struct stat mystat; mystat.st_atime;" yields errors, observable for example when building libgfortran in gcc: /x/gcc/libgfortran/intrinsics/stat.c:114:42: error: 'struct stat' has \ no member named 'st_atime'; did you mean 'st_atim'? 114 | sarray->base_addr[8 * stride] = sb.st_atime; | ^~~~~~~~ | st_atim (etc.) Trivially fixed by completing the reversion, removing the "&& !defined(__cris__)" in sys/stat.h. Beware: the net effect of the earlier related change to struct stat in sys/stat.h, leading up to the fix, *does* change its definition as a type. Thankfully, replacing members like "time_t st_atime; long st_spare1;" by "struct timespec st_atim;", ditto st_mtim and st_ctim, is layout-compatible. To wit, that change is "binary compatible". Incidentally, related to the simulator / Linux ABI, there's a transitional stage (see gensyscalls), reloading between "struct stat" (sys/stat.h) and "struct new_stat" (kernel/simulator) as necessary. Tested by a cris-elf gcc build (including libgfortran).
