//META: purpose=Boundary: arithmetic right-shift by 31 (`a >> 31`) on a 32-bit signed int lowers to `shr(%a, 31 : Int)` — the upper-edge valid amount; canonical "extract sign bit" idiom.

// The high-edge valid shift amount for a 32-bit signed value.
// On signed operands the doc notes the choice between arithmetic
// and logical right-shift is keyed by operand signedness — the
// signed input means an arithmetic shift, but the IR opcode is
// still the same `shr`.
