Browse Source 
vld1q_u8_x4 was added for aarch64 in the gcc 9.4.0 release:
https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/ChangeLog;h=7558c0a369ea8c74a2b9369049a2d1cc187dc050;hb=13c83c4cc679ad5383ed57f359e53e8d518b7842#l2100

fixes:
src/dsp/enc_neon.c: In function 'Intra4Preds_NEON':
src/dsp/enc_neon.c:974:37: warning: implicit declaration of function
  'vld1q_u8_x4'; did you mean 'vld1q_u8_x2'?
