Struct melior::dialect::ods::arith::TruncIOperation

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

A trunci operation. Integer truncation operation.

The integer truncation operation takes an integer input of width M and an integer destination type of width N. The destination bit-width must be smaller than the input bit-width (N < M). The top-most (N - M) bits of the input are discarded.

Example:

  %1 = arith.constant 21 : i5     // %1 is 0b10101
  %2 = arith.trunci %1 : i5 to i4 // %2 is 0b0101
  %3 = arith.trunci %1 : i5 to i3 // %3 is 0b101

  %5 = arith.trunci %0 : vector<2 x i32> to vector<2 x i16>
