Alternatively, the RISC-V V intrinsics can be viewed online.
Searching is done by finding entries that match all space-separated things. Things can be:
- regular text (
add), quoted text ("add packed"), regex (/\bmul/); - the above, in a specific field:
ret:int8,arg:/int\d+_t/, etc (if no field is specified, the checkboxes are used); - the above, negated:
!ret:void,!add,!name:maskz, etc.
Additionally, var=[name] will default the whole search to a specific variation.

General:
arg:*- intrinsics taking pointer argumentsarg6:""- intrinsics taking at least 6 arguments!arg1n:""- intrinsics taking no argumentsarg:int64 ret:int16- intrinsics taking 64-bit & returning 16-bit integers
x86-64 AVX-512:
var=base:name:mask name:_mm512- 512-bit intrinsics with "mask" in the name that's not in a variation
ARM NEON:
name:q_- keep only 128-bit intrinsics
