This uses the new SCRFile changes to generate a header file containing a list
of all the SCRs in a core to remove the magic constant "63" (the HTIF clock
divider control register) and replace it with a generated number (which is
still 63).
It looks like Chisel fails when I try to run it in parallel. This adds a lock
file to ensure that only a single Chisel instance is running at a time when
running the regressions.
make changed its priorties for resolving implicit rules, which causes different
behavior when running "make run-bmark-tests". This patch changes the hex file
rules to ensure they match between the two versions of make.
I've tried this with both make-3.81 and make-4.1, and they both work for me.
In order to have the buildbot support various types of failures it needs
to run different commands. Rather than modifying the regression script
to have a bunch of arguments I've just gone and made a makefile for
regressions instead.
This doesn't run torture right now because that's broken, but I'll add
support soon.
I want to be able to test the master of riscv-gnu-toolchain against the current
RTL as part of the buildbot. This flag takes a list of repositories (by their
submodule path) and updates those to the current master, which facilitates that
check.
This causes every command to be echo'd to stderr, and any failing
command will fail the whole script. Without this the regression
script will always pass.
It seems that the update process in the README is really out of date
(it refers to scala-2.8 and chisel-1.1). I've updated it to what I
believe to be correct, which now just consists of pulling the Chisel
submodule.
Note that I tried this myself, but when I did it I also ran an "sbt
package" in the Chisel submodule top-level directory (there's no "sbt"
directory in there any more). I believe it's not necessary to run
"sbt package", but I really know nothing about SBT...
I made a clean checkout of reference-chip yesterday and wasn't able to
build the debug emulator without first having built the non-debug
emulator. I just added a note to the README to say this.
