Previously VQ was of type long. Using uint64_t ensures it always matches the same type as the VG register. Note that in the Linux kernel, VQ is 16bits. We cast it up to 64bits immediately after reading to ensure we always use the same type throughout the code. gdb/ * aarch64-tdep.c (aarch64_read_description): Use uint64_t for VQ. * aarch64-tdep.h (aarch64_read_description): Likewise. * arch/aarch64.c (aarch64_create_target_description): Likewise. * arch/aarch64.h (aarch64_create_target_description): Likewise. * features/aarch64-sve.c (create_feature_aarch64_sve): Likewise. * nat/aarch64-sve-linux-ptrace.c(aarch64_sve_get_vq): Likewise. * nat/aarch64-sve-linux-ptrace.h (aarch64_sve_get_vq): Likewise.
