* signal: Add signum-{generic,arch}.hAdhemerval Zanella2020-07-071-32/+0
| | | | | | | | | | | | | | | | | | | | It refactor how signals are defined by each architecture. Instead of include a generic header (bits/signum-generic.h) and undef non-default values in an arch specific header (bits/signum.h) the new scheme uses a common definition (bits/signum-generic.h) and each architectures add its specific definitions on a new header (bits/signum-arch.h). For Linux it requires copy some system default definitions to alpha, hppa, and sparc. They are historical values and newer ports uses the generic Linux signum-arch.h. For Hurd the BSD signum is removed and moved to a new header (it is used currently only on Hurd). Checked on a build against all affected ABIs.

* Factor out shared definitions from bits/signum.h.Zack Weinberg2017-06-201-62/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the things defined by bits/signum.h are invariant across all supported operating systems. This patch factors out all of them to a new header bits/signum-generic.h, which each bits/signum.h will include and then override whichever things need adjustment. Normally that will mean, at most, adding or changing a few signal numbers. A user-visible side effect is that the obsolete signal constant SIGUNUSED (which is an alias for SIGSYS on all platforms that define it) is no longer exposed by any version of bits/signum.h. A side effect only relevant to glibc hackers is that _NSIG is now defined in terms of __SIGRTMAX, instead of the other way around. This is because __SIGRTMAX varies from platform to platform, but _NSIG==__SIGRTMAX+1 is true universally. If your platform doesn't support realtime signals, leave __SIGRTMAX equal to __SIGRTMIN. I also added a Linux-specific test to make sure that our signal constants match the ones in <asm/signal.h>, since we can't use that header (it's not even vaguely namespace-clean). * bits/signum-generic.h: Renamed from bits/signum.h. Add proper multiple include guard and misuse check. Define __SIGRTMIN = __SIGRTMAX = 32, and define _NSIG = __SIGRTMAX+1. Move definition of SIGIO to "archaic names for compatibility" section. * bits/signum.h: New file which just includes bits/signum-generic.h. * sysdeps/unix/bsd/bits/signum.h * sysdeps/unix/sysv/linux/bits/signum.h * sysdeps/unix/sysv/linux/alpha/bits/signum.h * sysdeps/unix/sysv/linux/hppa/bits/signum.h * sysdeps/unix/sysv/linux/mips/bits/signum.h * sysdeps/unix/sysv/linux/sparc/bits/signum.h Just include <bits/signum-generic.h> and then add or adjust signal constants. Do not define SIGUNUSED, SIGRTMIN, or SIGRTMAX. * signal/Makefile: Install bits/signum-generic.h. * signal/signal.h: Define SIGRTMIN and SIGRTMAX here. * sysdeps/generic/siglist.h: SIGSYS and SIGWINCH are universal. Prefer SIGPOLL to SIGIO. Simplify #ifdeffage. * sysdeps/unix/sysv/linux/tst-signal-numbers.sh: New test. * sysdeps/unix/sysv/linux/Makefile: Run it.
* Define SIG_HOLD for XPG4 (bug 21538).Joseph Myers2017-06-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Various bits/signum.h headers define SIG_HOLD if __USE_UNIX98. That should be __USE_XOPEN, as this macro is in XPG4. This patch fixes the conditionals accordingly. Because of other header bugs, this does not allow any XFAILs to be removed (however, the XPG4/signal.h/conform XFAIL only depends on a few such straightforward header bugs, not on the more complicated to fix ucontext_t issues, as ucontext_t isn't included in signal.h in XPG4). Tested for x86_64.
