Add Aarch64 SVE target description No code uses the new descriptions yet. gdb/ * aarch64-linux-nat.c (aarch64_linux_read_description): Add parmeter zero. * aarch64-linux-tdep.c (aarch64_linux_core_read_description): Likewise. * aarch64-tdep.c (tdesc_aarch64_list): Add. (aarch64_read_description): Use VQ to index tdesc_aarch64_list. (aarch64_gdbarch_init): Add parmeter zero. * aarch64-tdep.h (aarch64_read_description): Add VQ parmeter. * arch/aarch64.c (aarch64_create_target_description): Check VQ. * arch/aarch64.h (aarch64_create_target_description): Add VQ. parmeter. * doc/gdb.texinfo: Describe SVE feature * features/aarch64-sve.c: New file. gdbserver/ * linux-aarch64-tdesc.c (aarch64_linux_read_description): Add null VQ.
