The idea is to avoid tie one architecture definition with another and make platform change independent. - Move all common definitions (the ipc syscall commands) on a common header, ipc_ops.h. Since current IPC_64 default now on kernel is 0x100, some architectures require it to 0 (for instance x86_64) while others continue to use a non zero default regardless (powerpc). * sysdeps/unix/sysv/linux/aarch64/ipc_priv.h: New file. * sysdeps/unix/sysv/linux/alpha/ipc_priv.h: Avoid included other arch definition and define its own. * sysdeps/unix/sysv/linux/ipc_ops.h: New file. * sysdeps/unix/sysv/linux/x86_64/ipc_priv.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/ipc_priv.h: Likewise. * sysdeps/unix/sysv/linux/mips/ipc_priv.h: Remove file. * sysdeps/unix/sysv/linux/mips/mips64/ipc_priv.h: New file. * sysdeps/unix/sysv/linux/ipc_priv.h: Move ipc syscall operation definitions to common header. * sysdeps/unix/sysv/linux/powerpc/ipc_priv.h: Use common syscall operation from ipc_ops.h. --- ChangeLog | 12 +++++++ sysdeps/unix/sysv/linux/aarch64/ipc_priv.h | 32 ++++++++++++++++++ sysdeps/unix/sysv/linux/alpha/ipc_priv.h | 33 ++++++++++++++++++- sysdeps/unix/sysv/linux/ipc_ops.h | 30 +++++++++++++++++ sysdeps/unix/sysv/linux/ipc_priv.h | 23 +++++-------- sysdeps/unix/sysv/linux/mips/ipc_priv.h | 1 - sysdeps/unix/sysv/linux/mips/mips64/ipc_priv.h | 32 ++++++++++++++++++ sysdeps/unix/sysv/linux/powerpc/ipc_priv.h | 23 +++++-------- sysdeps/unix/sysv/linux/sparc/sparc64/ipc_priv.h | 41 ++++++++++++++++++++++++ sysdeps/unix/sysv/linux/x86_64/ipc_priv.h | 32 ++++++++++++++++++ 10 files changed, 227 insertions(+), 32 deletions(-) create mode 100644 sysdeps/unix/sysv/linux/aarch64/ipc_priv.h create mode 100644 sysdeps/unix/sysv/linux/ipc_ops.h delete mode 100644 sysdeps/unix/sysv/linux/mips/ipc_priv.h create mode 100644 sysdeps/unix/sysv/linux/mips/mips64/ipc_priv.h create mode 100644 sysdeps/unix/sysv/linux/sparc/sparc64/ipc_priv.h create mode 100644 sysdeps/unix/sysv/linux/x86_64/ipc_priv.h diff --git a/sysdeps/unix/sysv/linux/aarch64/ipc_priv.h b/sysdeps/unix/sysv/linux/aarch64/ipc_priv.h new file mode 100644 index 0000000..1a31396 --- /dev/null +++ b/sysdeps/unix/sysv/linux/aarch64/ipc_priv.h @@ -0,0 +1,32 @@ +/* Old SysV permission definition for Linux.
