From 2c46a66a3a24e94fbe78151b6a53f15972ef7e2b Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Fri, 7 Nov 2014 01:27:16 +0000 Subject: [PATCH] Remove __libc_waitpid function name. Continuing the removal of unused __libc_* function names, this patch removes the __libc_waitpid name. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch; __waitpid, which is exported from shared libc, changes from weak to strong on some configurations, which is of no significance). * include/sys/wait.h (__libc_waitpid): Remove declaration. * posix/waitpid.c (__libc_waitpid): Rename to __waitpid. (__waitpid): Don't define as alias. Use libc_hidden_def not libc_hidden_weak. (waitpid): Define as alias of __waitpid. * sysdeps/unix/bsd/waitpid.c (__libc_waitpid): Rename to __waitpid. (__waitpid): Don't define as alias. Use libc_hidden_def not libc_hidden_weak. (waitpid): Define as alias of __waitpid. * sysdeps/unix/sysv/linux/i386/syscalls.list (waitpid): Remove __libc_waitpid alias. * sysdeps/unix/sysv/linux/m68k/syscalls.list (waitpid): Likewise. * sysdeps/unix/sysv/linux/powerpc/syscalls.list (waitpid): Likewise. * sysdeps/unix/sysv/linux/sh/syscalls.list (waitpid): Likewise. * sysdeps/unix/sysv/linux/sparc/syscalls.list (waitpid): Likewise. * sysdeps/unix/sysv/linux/tile/waitpid.S (__libc_waitpid): Remove alias. * sysdeps/unix/sysv/linux/waitpid.c (__libc_waitpid): Rename to __waitpid. (__waitpid): Don't define as alias. Use libc_hidden_def not libc_hidden_weak. (waitpid): Define as alias of __waitpid. --- ChangeLog | 27 +++++++++++++++++++ include/sys/wait.h | 1 - posix/waitpid.c | 7 +++-- sysdeps/unix/bsd/waitpid.c | 7 +++-- sysdeps/unix/sysv/linux/i386/syscalls.list | 2 +- sysdeps/unix/sysv/linux/m68k/syscalls.list | 2 +- sysdeps/unix/sysv/linux/powerpc/syscalls.list | 2 +- sysdeps/unix/sysv/linux/sh/syscalls.list | 2 +- sysdeps/unix/sysv/linux/sparc/syscalls.list | 2 +- sysdeps/unix/sysv/linux/tile/waitpid.S | 2 -- sysdeps/unix/sysv/linux/waitpid.c | 7 +++-- 11 files changed, 41 insertions(+), 20 deletions(-) diff --git a/ChangeLog b/ChangeLog index 6f3a85f123..a8d9c4996d 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,30 @@ +2014-11-07 Joseph Myers + + * include/sys/wait.h (__libc_waitpid): Remove declaration. + * posix/waitpid.c (__libc_waitpid): Rename to __waitpid. + (__waitpid): Don't define as alias.
