5854fb5f7c SourceShrinker improvements (#1197) 
* SourceShrinker: preserve FIFO guarantees of slaves

TtoT is needed for write-through caches.

338e453a91 JTAG: Use new withClock way of overriding clocks (#1072) 
* JTAG: Use new withClock way of overriding clocks

the override clock way is deprecated

* JTAG: use withClock instead of override clock

* JTAG:  extend Module for ClockedCounter

* JTAG: Don't use deprecated clock constructs

* JTAG: Remove another override_clock

* Rename "NegativeEdgeLatch"

because it's not a latch, it's just a register on the negative edge of the clock.

* Use the appropriately named NegEdgeReg

* JTAG: Rename another NegativeEdgeLatch

e52d52ae99 Link PlusArg to emulator command line options 
- adds a mutable singleton (PlusArgArtefacts) to store information
  about Rocket PlusArgs
- adds methods to PlusArgArtefacts to emit C snippets that are
  consumed by emulator.cc for correct argument parsing and help text
  generation
- emits snippets in $(CONFIG).plusArgs via BaseCoreplex-set
  ElaborationArtefacts
- modify emulator/Makefrag-verilator to include $(CONFIG).plusArgs
- cleanup help text (docstring) for existing PlusArgs

e82328336e Add in a SimJTAG to connect to OpenOCD's remote-bitbang interface. 
This is simpler than JTAGVPI and is supported better by Verilor.
It is also the same thing Spike uses.

000cde2f8a Make ErrorDevice UNCACHEABLE instead of UNCACHED 
...even though it still supports Acquire.  This avoids needing to flush
the D$ on FENCE.I because of the presence of the ErrorDevice.

Andrew Waterman
ad0b9a0b1b Reduce cases in which FENCE.I must flush D$ 
Memory regions that are uncacheable or have get/put effects should not
reside in the D$, so there is no need to flush them.

Enforce physical-address canonicalization
 2018-01-03 12:06:18 -08:00
Andrew Waterman
ee1a9485df Enforce physical-address canonicalization 
When xLen > paddrBits, enforce that physical addresses are zero-extended.
This works by checking that the _virtual_ address is _sign_-extended, then
checking that its sign is positive.

7c9a1b0265 Correctly check for virtual-address canonicalization
