Struct melior::dialect::ods::arith::ShRSIOperation

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

A shrsi operation. Signed integer right-shift.

The shrsi operation shifts an integer value to the right by a variable amount. The integer is interpreted as signed. 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).

Example:

%1 = arith.constant 160 : i8               // %1 is 0b10100000
%2 = arith.constant 3 : i8
%3 = arith.shrsi %1, %2 : (i8, i8) -> i8   // %3 is 0b11110100
%4 = arith.constant 96 : i8                   // %4 is 0b01100000
%5 = arith.shrsi %4, %2 : (i8, i8) -> i8   // %5 is 0b00001100
