213bb26367 Drive invalidate_lr signal 
The DCache input for invalidating LR reservations was dangling.  Now
we wire it to false.

471f4c2695 change WriteMaskedPutBlockRegression for better bug detection 
Instead of sending puts back-to-back, separate the two puts with a get.
Also, stall a bit between each transaction. This makes sure the puts and
intermediate get are sent to the same transactor, which will cause the
data buffer to get overwritten between the two puts.

bda5772e98 Updates to the trace-generator: (1) Don't terminate via HTIF exit, which can cause other, unfinished, cores to be cut short. Instead emit FINISHED messsages allowing an external process to send a SIGTERM to the emulator once all cores have finished. (2) Add some support for greater address variation without having to recompile, disabled by default. (3) Generate atomic, LR/SC, and fence operations by default in addition to plain loads and stores. These changes require newer versions of files in the rocket-chip/scripts directory. I will submit a pull request for those too. 2016-03-18 12:11:11 +00:00

50f61687de Work around Chisel3's lack of 0-width wires 
This is super ugly, but it's necessary to get Chisel3 to compile.  Note
that this still fails simulations in Chisel3, so it might be wrong.
