Alpha: Adjust MEM alignment for block clear [PR115459]
By inference it appears to me that the same fix for PR target/115459
needs to be applied to the block clear operation that has been done for
block move, as implemented by commit ccfe71518039 ("[alpha] adjust MEM
alignment for block move [PR115459]").
gcc/
PR target/115459
* config/alpha/alpha.cc (alpha_expand_block_clear): Adjust MEM
to match inferred alignment.
