From 90aa3d09450903859e2845399729775b19bde50c Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Mon, 22 Dec 2014 21:42:03 +0000 Subject: Make __ASSUME_UTIMES hppa-specific. This patch makes __ASSUME_UTIMES hppa-specific, removing mentions of the macro from architecture-independent code and code for other architectures. (All other architectures either have the utimes syscall in all relevant kernel versions, or use the asm-generic interface so only have utimensat and won't get the utimes syscall.) A similar approach is used to that used for futimesat for MicroBlaze: if the kernel is recent enough that the utimes syscall can be assumed to be present, use the implementation in terms of the utimes syscall, and otherwise use the linux/generic implementation in terms of utimensat. Tested x86_64 that the disassembly of installed shared libraries is unchanged by the patch. Not tested for hppa. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_UTIMES): Do not define. * sysdeps/unix/sysv/linux/utimes.c: Do not include . (__utimes) [__NR_utimes]: Make code unconditional.
