alignment of the original data.
Also eliminate the call to the reimplementation of the AMO functions.
(One call was already converted to use the common function, and I've now
converted the other.)
It's honestly unknown how much of this works, but it's more likely to
work than what was previously implemented, I think, given that the
previou implementation was based on some basic misconceptions concerning
data alignment.
This includes renaming Fifo.bsv to Fifos.bsv to account for a case insensitive file system which confuses this library with FIFO.bsv.
Also this includes an update of the verilator flags that are needed for modern verilator.
Finally, some verilator flag changes for building with LLVM.
Now able to run multiple ISA tests in a single simulation run
connected to remote debugger DSharp, using either hart_reset or
ndm_reset between tests to bring the system back into reset state.
All Debug Module commands working:
- dm_reset, hart_reset, ndm_reset
- break (set breakpoint)
- step
- continue (until breakpoint of 'halt' command)
- halt
- read/write GPR, FPR, CSR, memory
- elf_load
Detail: an "instruction-fetch" response from mmioplatform to core
should be an "InstFetch". This was true for successful fabric reads,
but on error responses it was wrongly returned as a "DataAccess"
response. This was causing a deadlock.
