Disturbes a floating-point result by a relative error on the order of (-2^scale, 2^scale).
Performs which scalar operation on left and right and returns
the result.
Performs which operation on each component of left and
right, storing the result is stored in dest.
Performs which operation on the first component of left and right
and copies the other components from left. The result is stored in dest.
Calcultates either a + b + cb_in or a - b - cb_in depending on the value
of op and returns both the sum and the overflow bit. op is expected to be
either one of mir::BinOp::AddWithOverflow and mir::BinOp::SubWithOverflow.
Conditionally multiplies the packed floating-point elements in
left and right using the high 4 bits in imm, sums the calculated
products (up to 4), and conditionally stores the sum in dest using
the low 4 bits of imm.
Converts each element of op from floating point to signed integer.
Takes a 128-bit vector, transmutes it to [u64; 2] and extracts
the first value.
Horizontally performs which operation on adjacent values of
left and right SIMD vectors and stores the result in dest.
“Horizontal” means that the i-th output element is calculated
from the elements 2i and 2i+1 of the concatenation of left and
right.
Calculates absolute value of integers in op and stores the result in dest.
Conditionally loads from ptr according the high bit of each
element of mask. ptr does not need to be aligned.
Conditionally stores into ptr according the high bit of each
element of mask. ptr does not need to be aligned.
Compute the sum of absolute differences of quadruplets of unsigned
8-bit integers in left and right, and store the 16-bit results
in right. Quadruplets are selected from left and right with
offsets specified in imm.
Packs two N-bit integer vectors to a single N/2-bit integers.
Converts two 32-bit integer vectors to a single 16-bit integer
vector with signed saturation.
Converts two 16-bit integer vectors to a single 8-bit integer
vector with signed saturation.
Converts two 32-bit integer vectors to a single 16-bit integer
vector with unsigned saturation.
Converts two 16-bit signed integer vectors to a single 8-bit
unsigned integer vector with saturation.
Perform a carry-less multiplication of two 64-bit integers, selected from left and right according to imm8,
and store the results in dst.
Multiplies packed 16-bit signed integer values, truncates the 32-bit
product to the 18 most significant bits by right-shifting, and then
divides the 18-bit value by 2 (rounding to nearest) by first adding
1 and then taking the bits 1..=16.
Negates elements from left when the corresponding element in
right is negative. If an element from right is zero, zero
is written to the corresponding output element.
In other words, multiplies left with right.signum().
Gets equivalent rustc_apfloat::Round from rounding mode immediate of
round.{ss,sd,ps,pd} intrinsics.
Shifts each element of left by a scalar amount. The shift amount
is determined by the lowest 64 bits of right (which is a 128-bit vector).
Shifts each element of left by the corresponding element of right.
Splits op (which must be a SIMD vector) into 128-bit chunks.
Calculates two booleans.
Calculates two booleans.
Performs which scalar operation on op and returns the result.
Performs which operation on each component of op, storing the
result is stored in dest.
Performs which operation on the first component of op and copies
the other components. The result is stored in dest.
