If a IS_IN_* macro is defined, then NOT_IN_libc is always defined, except obviously for IS_IN_libc. There's no need to check for both. Verified on x86_64 and i686 that the source is unchanged. * include/libc-symbols.h: Remove unnecessary check for NOT_IN_libc. * nptl/pthreadP.h: Likewise. * sysdeps/aarch64/setjmp.S: Likewise. * sysdeps/alpha/setjmp.S: Likewise. * sysdeps/arm/sysdep.h: Likewise. * sysdeps/i386/setjmp.S: Likewise. * sysdeps/m68k/setjmp.c: Likewise. * sysdeps/posix/getcwd.c: Likewise. * sysdeps/powerpc/powerpc32/setjmp-common.S: Likewise. * sysdeps/powerpc/powerpc64/setjmp-common.S: Likewise. * sysdeps/s390/s390-32/setjmp.S: Likewise. * sysdeps/s390/s390-64/setjmp.S: Likewise. * sysdeps/sh/sh3/setjmp.S: Likewise. * sysdeps/sh/sh4/setjmp.S: Likewise. * sysdeps/unix/alpha/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/aarch64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/i386/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/ia64/setjmp.S: Likewise. * sysdeps/unix/sysv/linux/ia64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/sh/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/tile/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/x86_64/sysdep.h: Likewise. * sysdeps/x86_64/setjmp.S: Likewise.
