Date: Fri, 13 May 2016 09:26:14 -0400 Message-Id: <1e3999cce2297684a2828e0ef3a15ff8555dd264.1463145139.git.zackw@panix.com> In-Reply-To: References: MIME-Version: 1.0 In-Reply-To: References: Presently sys/sysmacros.h is entirely defined in sysdeps. This would mean that the deprecation logic coming up in patch #4 would have to be written twice (in generic/ and unix/sysv/linux/). To avoid that, hoist all but the unavoidably system-dependent logic to misc/, leaving a bits/ header behind. This also promotes the Linux-specific encoding of dev_t, which accommodated 32-bit major and minor numbers in a 64-bit dev_t, to generic, as glibc's dev_t is always 64 bits wide. The former Linux implementation used inline functions to avoid evaluating arguments more than once. After this change, all platforms use inline functions, which means that three new symbols are added to the generic ABI. New ports henceforth need only provide bits/sysmacros.h defining macros __makedev_body, __major_body, and __minor_body. While I was at it, I added a basic round-trip test for these functions. ChangeLog: * misc/sys/sysmacros.h: New file with generic inline-function-based implementation of major, minor, makedev, derived from the old sysdeps/unix/sysv/linux/sys/sysmacros.h. * include/sys/sysmacros.h: New wrapper. * sysdeps/unix/sysv/linux/sys/sysmacros.h: Move ... * bits/sysmacros.h: ... here; only define __makedev_body, __major_body, __minor_body. * sysdeps/generic/sys/sysmacros.h: Deleted. * sysdeps/unix/sysv/linux/makedev.c: Move ... * misc/makedev.c: ... here; make generic. * misc/tst-makedev.c: New test. * misc/Makefile (headers): Add sys/sysmacros.h, bits/sysmacros.h. (routines): Add makedev. (tests): Add tst-makedev. * misc/Versions [GLIBC_2.24]: Add gnu_dev_major, gnu_dev_minor, gnu_dev_makedev. * posix/Makefile (headers): Remove sys/sysmacros.h. * sysdeps/unix/sysv/linux/Makefile (sysdep_routines): Remove makedev. * sysdeps/arm/nacl/libc.abilist: Add GLIBC_2.24, gnu_dev_major, gnu_dev_makedev, gnu_dev_minor. * sysdeps/unix/sysv/linux/aarch64/libc.abilist * sysdeps/unix/sysv/linux/alpha/libc.abilist * sysdeps/unix/sysv/linux/arm/libc.abilist * sysdeps/unix/sysv/linux/hppa/libc.abilist * sysdeps/unix/sysv/linux/i386/libc.abilist * sysdeps/unix/sysv/linux/ia64/libc.abilist * sysdeps/unix/sysv/linux/m68k/coldfire/libc.abilist * sysdeps/unix/sysv/linux/m68k/m680x0/libc.abilist * sysdeps/unix/sysv/linux/microblaze/libc.abilist * sysdeps/unix/sysv/linux/mips/mips32/fpu/libc.abilist * sysdeps/unix/sysv/linux/mips/mips32/nofpu/libc.abilist * sysdeps/unix/sysv/linux/mips/mips64/n32/libc.abilist * sysdeps/unix/sysv/linux/mips/mips64/n64/libc.abilist * sysdeps/unix/sysv/linux/nios2/libc.abilist * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libc.abilist * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libc.abilist * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc-le.abilist * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc.abilist * sysdeps/unix/sysv/linux/s390/s390-32/libc.abilist * sysdeps/unix/sysv/linux/s390/s390-64/libc.abilist * sysdeps/unix/sysv/linux/sh/libc.abilist * sysdeps/unix/sysv/linux/sparc/sparc32/libc.abilist * sysdeps/unix/sysv/linux/sparc/sparc64/libc.abilist * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/libc.abilist * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libc.abilist * sysdeps/unix/sysv/linux/x86_64/64/libc.abilist * sysdeps/unix/sysv/linux/x86_64/x32/libc.abilist: Add GLIBC_2.24. --- bits/sysmacros.h | 60 ++++++++++++ include/sys/sysmacros.h | 1 + misc/Makefile | 8 +- misc/Versions | 3 + misc/makedev.c | 40 ++++++++ misc/sys/sysmacros.h | 56 +++++++++++ misc/tst-makedev.c | 104 +++++++++++++++++++++ posix/Makefile | 2 +- sysdeps/arm/nacl/libc.abilist | 4 + sysdeps/generic/sys/sysmacros.h | 30 ------ sysdeps/unix/sysv/linux/Makefile | 2 +- sysdeps/unix/sysv/linux/aarch64/libc.abilist | 1 + sysdeps/unix/sysv/linux/alpha/libc.abilist | 1 + sysdeps/unix/sysv/linux/arm/libc.abilist | 1 + sysdeps/unix/sysv/linux/hppa/libc.abilist | 1 + sysdeps/unix/sysv/linux/i386/libc.abilist | 1 + sysdeps/unix/sysv/linux/ia64/libc.abilist | 1 + sysdeps/unix/sysv/linux/m68k/coldfire/libc.abilist | 1 + sysdeps/unix/sysv/linux/m68k/m680x0/libc.abilist | 1 + sysdeps/unix/sysv/linux/makedev.c | 40 -------- sysdeps/unix/sysv/linux/microblaze/libc.abilist | 1 + .../unix/sysv/linux/mips/mips32/fpu/libc.abilist | 1 + .../unix/sysv/linux/mips/mips32/nofpu/libc.abilist | 1 + .../unix/sysv/linux/mips/mips64/n32/libc.abilist | 1 + .../unix/sysv/linux/mips/mips64/n64/libc.abilist | 1 + sysdeps/unix/sysv/linux/nios2/libc.abilist | 1 + .../sysv/linux/powerpc/powerpc32/fpu/libc.abilist | 1 + .../linux/powerpc/powerpc32/nofpu/libc.abilist | 1 + .../sysv/linux/powerpc/powerpc64/libc-le.abilist | 1 + .../unix/sysv/linux/powerpc/powerpc64/libc.abilist | 1 + sysdeps/unix/sysv/linux/s390/s390-32/libc.abilist | 1 + sysdeps/unix/sysv/linux/s390/s390-64/libc.abilist | 1 + sysdeps/unix/sysv/linux/sh/libc.abilist | 1 + sysdeps/unix/sysv/linux/sparc/sparc32/libc.abilist | 1 + sysdeps/unix/sysv/linux/sparc/sparc64/libc.abilist | 1 + sysdeps/unix/sysv/linux/sys/sysmacros.h | 65 ------------- .../sysv/linux/tile/tilegx/tilegx32/libc.abilist | 1 + .../sysv/linux/tile/tilegx/tilegx64/libc.abilist | 1 + sysdeps/unix/sysv/linux/x86_64/64/libc.abilist | 1 + sysdeps/unix/sysv/linux/x86_64/x32/libc.abilist | 1 + 40 files changed, 302 insertions(+), 140 deletions(-) create mode 100644 bits/sysmacros.h create mode 100644 include/sys/sysmacros.h create mode 100644 misc/makedev.c create mode 100644 misc/sys/sysmacros.h create mode 100644 misc/tst-makedev.c delete mode 100644 sysdeps/generic/sys/sysmacros.h delete mode 100644 sysdeps/unix/sysv/linux/makedev.c delete mode 100644 sysdeps/unix/sysv/linux/sys/sysmacros.h diff --git a/bits/sysmacros.h b/bits/sysmacros.h new file mode 100644 index 0000000..544a9cf --- /dev/null +++ b/bits/sysmacros.h @@ -0,0 +1,60 @@ +/* Definitions of macros to access `dev_t' values. + Copyright (C) 1996-2016 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.
