Subject: decode1: Make ld/std and lwa not be single-issue
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=af909840e6f35d9b345b2a23373076d1386e0e50;p=microwatt.git

decode1: Make ld/std and lwa not be single-issue

These were missed earlier when the single-issue flag was turned off on
the other loads and stores by commit 1a244d34707a ("Remove single-issue
constraint for most loads and stores").
