Hide internal signal functions [BZ #18822]
Hide internal signal functions to allow direct access within libc.so and libc.a without using GOT nor PLT. __GI___kill and __GI___sigaltstack are defined when syscalls.list is used to generate them. Otherwise libc_hidden_def is needed explicitly. [BZ #18822] * include/signal.h (__kill): Add libc_hidden_proto. (__sigblock): Likewise. (__sigprocmask): Likewise. (__sigaltstack): Likewise. * signal/kill.c (__kill): Add libc_hidden_def. * signal/sigblock.c (__sigblock): Likewise. * signal/sigprocmask.c (__sigprocmask): Likewise. * sysdeps/mach/hurd/kill.c (__kill): Likewise. * sysdeps/mach/hurd/sigaltstack.c (__sigaltstack): Likewise. * sysdeps/mach/hurd/sigprocmask.c (__sigprocmask): Likewise. * sysdeps/posix/sigblock.c (__sigblock): Likewise. * sysdeps/unix/sysv/linux/alpha/sigprocmask.c (__sigprocmask): Likewise. * sysdeps/unix/sysv/linux/ia64/sigprocmask.c (__sigprocmask): Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/sigprocmask.c (__sigprocmask): Likewise. * sysdeps/unix/sysv/linux/sigprocmask.c (__sigprocmask): Likewise. * /sysdeps/unix/sysv/linux/sparc/sparc64/sigprocmask.c (__sigprocmask): Likewise. * sysdeps/unix/sysv/linux/x86_64/sigprocmask.c (__sigprocmask): Likewise.
