x86-64, ARM, and RISC-V V intrinsics viewer

Usage:

1. make download (or some of make download-x86, make download-arm, make download-riscv)
2. open index.html

Alternatively, the RISC-V V intrinsics can be viewed online.

Search

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.

Searchable fields

term	checkbox	description
name:	intrinsic	intrinsic name
ret:	intrinsic	return value
arg:	intrinsic	argument type
type:	intrinsic	any result or argument type
argn:	—	argument name
arg[N]n:	—	n-th (1-indexed) argument name, e.g. arg3n:/\bmask\b/
arg[N]:	—	n-th (1-indexed) argument type
desc:	description	description
inst:	instruction	instruction
oper:	operation	operation
cat:	category	category (nesting is |-separated)
arch:	—	architecture (nesting is |-separated)
var=[name]:	—	search in specific variation, e.g. var=base:arg:bool

Search examples

General:

• arg:* - intrinsics taking pointer arguments
• arg6:"" - intrinsics taking at least 6 arguments
• !arg1n:"" - intrinsics taking no arguments
• arg: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

RISC-V rvv:

• var=_m - maskable intrinsics
• var=base arg:vbool or var=base:arg:vbool - non-masked intrinsics taking a boolean vector argument
• !name:/_.(8|16|64)m/ !name:/mf?[248]$/ !name:/_b(1|2|4|16|32|64)$/ - discard repetitive intrinsics, keep LMUL=1, 32-bit element
• !argn:/vl$/ - intrinsics that don't require a specified VL
