Subject: [PATCH 1/4] pipeline: improve the drop instruction
Date: Fri, 26 Nov 2021 23:51:26 +0000 [thread overview]
Message-ID: <20211126235129.35781-1-cristian.dumitrescu@intel.com> (raw)
The output port to be used as the drop port is now determined when the
drop instruction is executed as opposed to being statically determined
at instruction translation time and hardcoded in the opcode.
