cfallin opened PR #1954 from b1649432 to main:

The failure to mask the amount triggered a panic due to a subtraction
overflow check; see
https://bugzilla.mozilla.org/show_bug.cgi?id=1649432. Attempting to
shift by an out-of-range amount should be defined to shift by an amount
mod the operand size (i.e., masked to 5 bits for 32-bit shifts, or 6
bits for 64-bit shifts).
