Expand description

SIMD intrinsic operations.

These map directly to hardware SIMD instructions on supported targets.

Variants§

§

Add

Vector add: result[i] = a[i] + b[i]

§

Sub

Vector subtract: result[i] = a[i] - b[i]

§

Mul

Vector multiply: result[i] = a[i] * b[i]

§

Div

Vector divide: result[i] = a[i] / b[i]

§

Fmadd

Fused multiply-add: result[i] = a[i] * b[i] + c[i]

§

Fmsub

Fused multiply-subtract: result[i] = a[i] * b[i] - c[i]

§

Fnmadd

Fused negative multiply-add: result[i] = -(a[i] * b[i]) + c[i]

§

Hadd

Horizontal add (pairwise): hadd([a,b,c,d], [e,f,g,h]) = [a+b, c+d, e+f, g+h]

§

HorizontalSum

Horizontal sum (reduce all elements): sum([a,b,c,d]) = a+b+c+d

§

Min

Vector minimum: result[i] = min(a[i], b[i])

§

Max

Vector maximum: result[i] = max(a[i], b[i])

§

CmpEq

Vector compare equal: result[i] = a[i] == b[i] ? ~0 : 0

§

CmpLt

Vector compare less than: result[i] = a[i] < b[i] ? ~0 : 0

§

CmpLe

Vector compare less or equal: result[i] = a[i] <= b[i] ? ~0 : 0

§

Broadcast

Broadcast scalar to all lanes

§

Extract

Extract element from vector

§

Insert

Insert element into vector

§

Shuffle

Shuffle/permute elements

§

LoadAligned

Aligned load

§

LoadUnaligned

Unaligned load

§

StoreAligned

Aligned store

§

StoreUnaligned

Unaligned store
