Subject: Reset src_l latch on issue_i
X-Git-Url: https://git.libre-soc.org/?p=soc.git;a=commitdiff_plain;h=25a0da60056af979b6dca95270f3ac19a5219a87

Reset src_l latch on issue_i

When the input operand is masked, there will be no go_i pulse to
reset the src_l latch, so we force it to reset on issue_i, as well.
