NEON vminvq_u32 and vmaxvq_u32

hi,

i spend again fews hours on neon and checking vminvq_u32  and vmaxvq_u32 i remark that i cannot find any information about those two functions.

if i got  uint32x4_t mask1 = vcltq_s32(uint32x4_t,const) and mask1 return  [0]4294967295  [1]4294967295  [2]4294967295  [3]4294967295, so all bits to 1. and all compute diff are OK.

doing  "if ( vminvq_u32(mask1) > 0 )" is like if (data1 OK AND  data2 OK AND data3 OK  AND data4 OK) and "if ( vminvq_u32(mask1) > 0 )" would be OK too. So it is and AND check

and  "if ( vmaxvq_u32(mask1) > 0 )" would also be OK.

if the result of mask1 return  [0]4294967295  [1]0  [2]4294967295  [3]4294967295

"if ( vminvq_u32(mask1) > 0 )" would not be OK but "if ( vmaxvq_u32(mask1) > 0 )" will be OK. So it is like if (data1 OK OR  data2 OK OR data3 OK  OR data4 OK)

if the result of mask1 return  [0]0  [1]0  [2]0  [3]0, "if ( vminvq_u32(mask1) > 0 )" and  "if ( vmaxvq_u32(mask1) > 0 )" will not be OK.

so vminvq is like an AND and vmaxvq an OR.

So what is the use of VAND, VBIC, VEOR, VORN, VORR function.

PS: but using vminvq_s32 and vmaxvq_s32 it does not work.

thanks again for your time ;))
