The types affected are __sig_atomic_t, sig_atomic_t, __sigset_t, sigset_t, sigval_t, sigevent_t, and siginfo_t. __sig_atomic_t is a scalar, so it's now directly available from bits/types.h. The others get bits/types/ headers. Side effects include: There have been small changes to which non-signal headers expose which subset of the signal-related types. A couple of architectures' nested siginfo_t fields had to be renamed to prevent undesired macro expansion. Internal code that wants to manipulate signal masks must now include <sigsetops.h> (which is not installed) and should be aware that __sigaddset, __sigandset, __sigdelset, __sigemptyset, and __sigorset no longer return a value (unlike the public API). Relatedly, the public signal.h no longer declares any of those functions. The obsolete sigmask() macro no longer has a system-specific definition -- in the cases where it matters, it didn't work anyway. New Linux architectures should create bits/siginfo-arch.h and/or bits/siginfo-consts-arch.h to customize their siginfo_t, rather than duplicating everything in bits/siginfo.h (which no longer exists). Add new __SI_* macros if necessary. Ports to other operating systems are strongly encouraged to generalize this scheme further. * bits/sigevent-consts.h * bits/siginfo-consts.h * bits/types/__sigset_t.h * bits/types/sigevent_t.h * bits/types/siginfo_t.h * sysdeps/unix/sysv/linux/bits/sigevent-consts.h * sysdeps/unix/sysv/linux/bits/siginfo-consts.h * sysdeps/unix/sysv/linux/bits/types/__sigset_t.h * sysdeps/unix/sysv/linux/bits/types/sigevent_t.h * sysdeps/unix/sysv/linux/bits/types/siginfo_t.h: New system-dependent bits headers. * sysdeps/unix/sysv/linux/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/bits/siginfo-consts-arch.h * sysdeps/unix/sysv/linux/ia64/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/ia64/bits/siginfo-consts-arch.h * sysdeps/unix/sysv/linux/mips/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/sparc/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/tile/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/tile/bits/siginfo-consts-arch.h * sysdeps/unix/sysv/linux/x86/bits/siginfo-arch.h: New Linux-only system-dependent bits headers. * signal/bits/types/sig_atomic_t.h * signal/bits/types/sigset_t.h * signal/bits/types/sigval_t.h: New non-system-dependent bits headers. * sysdeps/generic/sigsetops.h * sysdeps/unix/sysv/linux/sigsetops.h: New internal headers. * include/bits/types/sig_atomic_t.h * include/bits/types/sigset_t.h * include/bits/types/sigval_t.h: New wrappers. * signal/sigsetops.h * bits/siginfo.h * bits/sigset.h * sysdeps/unix/sysv/linux/bits/siginfo.h * sysdeps/unix/sysv/linux/bits/sigset.h * sysdeps/unix/sysv/linux/ia64/bits/siginfo.h * sysdeps/unix/sysv/linux/mips/bits/siginfo.h * sysdeps/unix/sysv/linux/s390/bits/siginfo.h * sysdeps/unix/sysv/linux/sparc/bits/siginfo.h * sysdeps/unix/sysv/linux/tile/bits/siginfo.h * sysdeps/unix/sysv/linux/x86/bits/siginfo.h: Deleted. * signal/Makefile, sysdeps/unix/sysv/linux/Makefile: Update lists of installed headers. * posix/bits/types.h: Define __sig_atomic_t here. * signal/signal.h: Use the new bits headers; no need to handle __need_sig_atomic_t nor __need_sigset_t.
