Binary search remains our friend.
Suppose you add an ought-to-be-benign pattern to PPC64.rules,
and make.bash starts crashing. You can guard the pattern(s)
with config.DebugTest:
(Eq8 x y) && config.DebugTest && isSigned(x.Type) &&
isSigned(y.Type) ->
(Equal (CMPW (SignExt8to32 x) (SignExt8to32 y)))
and then
gossahash -s ./make.bash
...
(go drink beer while silicon minions toil)
...
Trying ./make.bash args=[], env=[GOSSAHASH=100110010111110]
./make.bash failed (1 distinct triggers): exit status 1
Trigger string is 'GOSSAHASH triggered (*importReader).readByte',
repeated 1 times
Review GSHS_LAST_FAIL.0.log for failing run
Finished with GOSSAHASH=100110010111110

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
