Hi! Enclosed is a trunk patch. I wonder how arm setrlimit could work, when it was using i386 *rlimit* stubs but with RLIM_INFINITY (~0UL>>1), so this patch adds arm resource.h, plus there is really no need to limit the old getrlimit64/setrlimit64 to 2GB when RLIM64_INFINITY is much larger and we're using a 64bit type to hold resource limits. This e.g. removes the need for two different setrlimit64 calls (because both are the same and equal to the generic version) and oldgetrlimit64 will report rlimits up to 4GB. 2000-01-24 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/arm/bits/resource.h: New file. * sysdeps/unix/sysv/linux/arm/Makefile: Remove oldsetrlimit64.c. * sysdeps/unix/sysv/linux/i386/Makefile: Likewise. * sysdeps/unix/sysv/linux/i386/Dist: Likewise. * sysdeps/unix/sysv/linux/arm/Versions: Remove setrlimit64@GLIBC_2.1.3. * sysdeps/unix/sysv/linux/i386/Versions: Likewise. * sysdeps/unix/sysv/linux/arm/oldsetrlimit64.c: Remove. * sysdeps/unix/sysv/linux/i386/oldsetrlimit64.c: Likewise. * sysdeps/unix/sysv/linux/arm/setrlimit64.c: Likewise. * sysdeps/unix/sysv/linux/i386/setrlimit64.c: Likewise. * sysdeps/unix/sysv/linux/i386/oldgetrlimit64.c: Call __new_getrlimit, so that setrlimit64@GLIBC_2.1 can report limits above 2G. * sysdeps/unix/sysv/linux/sparc/sparc32/syscalls.list (getrlimit, setrlimit): Remove syscall stubs, add normal syscalls. * sysdeps/unix/sysv/linux/sparc/sparc64/syscalls.list (setrlimit): Remove syscall stub. --- libc/sysdeps/unix/sysv/linux/arm/bits/resource.h.jj Mon Jan 24 09:42:18 2000 +++ libc/sysdeps/unix/sysv/linux/arm/bits/resource.h Sun Dec 19 00:49:02 1999 @@ -0,0 +1,205 @@ +/* Bit values & structures for resource limits.
