Adhemerval Zanella b8386c2859 Remove PREPARE_VERSION and PREPARE_VERSION_KNOW ... This patch removes the PREPARE_VERSION and PREPARE_VERSION_KNOW macro and uses a static inline function instead, get_vdso_symbol. Each architecture that supports vDSO must define the Linux version and its hash for symbol resolution (VDSO_NAME and VDSO_HASH macro respectively). It also organizes the HAVE_*_VSYSCALL for mips, powerpc, and s390 to define them on a common header. The idea is to require less code to configure and enable vDSO support for newer ports. No semantic changes are expected. Checked with a build against all affected architectures. * sysdeps/unix/make-syscalls.sh: Make vDSO call use get_vdso_symbol. * sysdeps/unix/sysv/linux/aarch64/gettimeofday.c (__gettimeofday): Use get_vdso_symbol instead of _dl_vdso_vsym. * sysdeps/unix/sysv/linux/powerpc/time.c (time): Likewise. * sysdeps/unix/sysv/linux/riscv/flush-icache.c (__lookup_riscv_flush_icache): Likewise. * sysdeps/unix/sysv/linux/x86/gettimeofday.c (__gettimeofday): Likewise. * sysdeps/unix/sysv/linux/x86/time.c (time): Likewise. * sysdeps/unix/sysv/linux/powerpc/gettimeofday.c: Likewise. * sysdeps/unix/sysv/linux/aarch64/init-first.c: Likewise. * sysdeps/unix/sysv/linux/arm/init-first.c: Likewise. * sysdeps/unix/sysv/linux/i386/init-first.c: Likewise. * sysdeps/unix/sysv/linux/mips/init-first.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/init-first.c: Likewise. * sysdeps/unix/sysv/linux/riscv/init-first.c: Likewise. * sysdeps/unix/sysv/linux/sparc/init-first.c: Likewise. * sysdeps/unix/sysv/linux/s390/init-first.c: Likewise. * sysdeps/unix/sysv/linux/x86_64/init-first.c: Likewise. * sysdeps/unix/sysv/linux/aarch64/sysdep.h (VDSO_NAME, VDSO_HASH): Define. * sysdeps/unix/sysv/linux/arm/sysdep.h (VDSO_NAME, VDSO_HASH): Likewise. * sysdeps/unix/sysv/linux/i386/sysdep.h (VDSO_NAME, VDSO_HASH): Likewise. * sysdeps/unix/sysv/linux/riscv/sysdep.h (VDSO_NAME, VDSO_HASH): Likewise. * sysdeps/unix/sysv/linux/sparc/sysdep.h (VDSO_NAME, VDSO_HASH): Likewise. * sysdeps/unix/sysv/linux/x86_64/sysdep.h (VDSO_NAME, VDSO_HASH): Likewise. * sysdeps/unix/sysv/linux/mips/mips32/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Remove definition. * sysdeps/unix/sysv/linux/mips/mips64/n32/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h (HAVE_CLOCK_GETRES_VSYSCALL, HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL, HAVE_GETCPU_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h (HAVE_CLOCK_GETRES_VSYSCALL, HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL, HAVE_GETCPU_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/sysdep.h: New file. * sysdeps/unix/sysv/linux/powerpc/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/s390/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/dl-vdso.h (PREPARE_VERSION, PREPARE_VERSION_KNOWN, VDSO_NAME_LINUX_2_6, VDSO_HASH_LINUX_2_6, VDSO_NAME_LINUX_2_6_15, VDSO_HASH_LINUX_2_6_15, VDSO_NAME_LINUX_2_6_29, VDSO_HASH_LINUX_2_6_29, VDSO_NAME_LINUX_4_15, VDSO_HASH_LINUX_4_15): Remove defines.
