Struct ShRSIOperation 

pub struct ShRSIOperation<'c> { /* private fields */ }

A shrsi operation. Signed integer right-shift.

The shrsi operation shifts an integer value of the first operand to the right by the value of the second operand. The first operand is interpreted as signed, and the second operand is interpreter as unsigned. The high order bits in the output are filled with copies of the most-significant bit of the shifted value (which means that the sign of the value is preserved). If the value of the second operand is greater or equal than bitwidth of the first operand, then the operation returns poison.

If the exact attribute is present, the result value of shrsi is a poison value if any of the bits shifted out are non-zero.

Example:

%1 = arith.constant 160 : i8         // %1 is 0b10100000
%2 = arith.constant 3 : i8
%3 = arith.shrsi %1, %2 exact : i8   // %3 is 0b11110100
%4 = arith.constant 98 : i8          // %4 is 0b01100010
%5 = arith.shrsi %4, %2 : i8         // %5 is 0b00001100

Trait Implementations

impl<'c> Clone for ShRSIOperation<'c>

fn clone(&self) -> ShRSIOperation<'c>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'c> Debug for ShRSIOperation<'c>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'b> From<ShRSIOperation<'b>> for ArithDialectOperation<'b>

fn from(op: ShRSIOperation<'b>) -> Self

Converts to this type from the input type.

impl<'c> From<ShRSIOperation<'c>> for Operation<'c>

fn from(operation: ShRSIOperation<'c>) -> Self

Converts to this type from the input type.

impl<'c> PartialEq for ShRSIOperation<'c>

fn eq(&self, other: &ShRSIOperation<'c>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
