From 45ff2bfcb34228ef8d36306a9691d1e540a6468a Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Fri, 19 Aug 2016 11:18:40 -0300 Subject: Consolidate posix_fallocate{64} implementations This patch consolidates all the posix_fallocate{64} implementation for Linux in only one (sysdeps/unix/sysv/linux/posix_fallocate{64}.c). It also removes the syscall from the auto-generation using assembly macros. The macro SYSCALL_LL{64} is used to handle the offset argument along with the new INTERNAL_SYSCALL_CALL macro to define correct argument count for internal INTERNAL_SYSCALL call. Tested on x86_64, i686, x32, aarch64, ppc64le, and armhf. * io/Makefile (tests): Add tst-posix_fallocate and tst-posix_fallocate64. * io/tst-posix_fallocate-common.c: New file. * io/tst-posix_fallocate.c: Likewise. * io/tst-posix_fallocate64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/posix_fallocate.c: Remove file. * sysdeps/unix/sysv/linux/mips/mips64/n32/posix_fallocate64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fallocate.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fallocate64.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/posix_fallocate.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/posix_fallocate64.c: Likewise. * sysdeps/unix/sysv/linux/posix_fallocate.c (posix_fallocate): Use SYSCALL_LL to pass both offset and len arguments. * sysdeps/unix/sysv/linux/posix_fallocate64.c (posix_fallocate64): Likewise. * sysdeps/unix/sysv/linux/x86_64/syscalls.list (pwrite64): Add __libc_pwrite64 alias used by posix_fallocate64. --- io/tst-posix_fallocate64.c | 44 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 io/tst-posix_fallocate64.c (limited to 'io/tst-posix_fallocate64.c') diff --git a/io/tst-posix_fallocate64.c b/io/tst-posix_fallocate64.c new file mode 100644 index 0000000000..0c2f66eb8c --- /dev/null +++ b/io/tst-posix_fallocate64.c @@ -0,0 +1,44 @@ +/* Basic posix_fallocate tests (with _FILE_OFFSET_BITS). + Copyright (C) 2016 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
