[PATCH] Remove __ASSUME_IPC64
- From: Andreas Schwab <schwab at suse dot de>
- To: libc-alpha at sourceware dot org
- Date: Tue, 18 Aug 2015 12:52:11 +0200
- Subject: [PATCH] Remove __ASSUME_IPC64
- Authentication-results: sourceware.org; auth=none
PowerPC has always used __IPC_64 like most other architectures, which
means that __ASSUME_IPC64 is now always true. This also makes all other
architecture implementations that use the ipc syscall identical to the
generic version.
* sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_IPC64):
Don't define.
* sysdeps/unix/sysv/linux/powerpc/kernel-features.h
(__ASSUME_IPC64): Don't undef.
* sysdeps/unix/sysv/linux/msgctl.c: Don't check for __ASSUME_IPC64.
* sysdeps/unix/sysv/linux/semctl.c: Likewise.
* sysdeps/unix/sysv/linux/shmctl.c: Likewise.
* sysdeps/unix/sysv/linux/i386/msgctl.c: Remove.
* sysdeps/unix/sysv/linux/i386/semctl.c: Remove.
* sysdeps/unix/sysv/linux/i386/shmctl.c: Remove.
* sysdeps/unix/sysv/linux/m68k/msgctl.c: Remove.
* sysdeps/unix/sysv/linux/m68k/semctl.c: Remove.

* sysdeps/unix/sysv/linux/s390/s390-32/msgctl.c: Remove.
* sysdeps/unix/sysv/linux/s390/s390-32/semctl.c: Remove.
* sysdeps/unix/sysv/linux/s390/s390-32/shmctl.c: Remove.
