Thank you for your understanding.
In the SSAT instruction description it says:
ASR #32 Arithmetic right shift by 32 bits, permitted only for encoding A1. Encoded as sh = 1, immsh = 0b00000.
ASR #32 Arithmetic right shift by 32 bits, permitted only for encoding A1.
Encoded as sh = 1, immsh = 0b00000.
What does that mean?
Isn't ASR #32 the same as ASR #31?
I understand that it shifts (with "sign extension") the whole 32-bit value out and leaves only the sign extension bits
that are "copies" of the highest bit of the original value.
What am I missing here?
