Philippe Sauter	68a9aa7c29	peepopt: handle offset too large in shiftadd ... If the offset is larger than the signal itself, meaning the signal is completely shifted out, it tried to extract a negative amount of bits from the old signal. This RTL pattern is suspicious since it is a complicated way of arriving at a constant value, so we warn the user.	2024-01-26 16:44:30 +01:00
