vim: set sw=8 noet :
* Checker should let us check data
* Fetch load
* Indirect load
* Indirect store
* Exec load
* Exec store
* Checker should print mismatches on its own instead
of depending on the caller
* Make it complete
* Make it pretty
* Deadman timer
* D-side cache
* Store forwarding
* Cache consistency between I and D side
* Senior store commit
* Shared between exec and indir stages
* Arbitration to reduce total port count
* Alternative: make separate indir and exec caches, depend on
cache consistency protocol
* Eliminate "unstores"
* SMC support
* Stores should snoop all upstream instruction PCs and restart if overlap
* Statistics about instruction mix
* Indirect loads
* Autoincrements
* Exec loads
* Exec stores
* Instructions with both exec load and exec store
* Instructions with both indirect and any exec memory
* Instructions with *three memory operations*
* Instructions with ~*all four memory operations*~
* Maybe histogram support, instructions with N memory ops
* Control register writes
* Per control register / bit
