Haven’t been able to distill a small test case, but the two remaining benchmarks that show correctness issues are:


./graal.sh -cp Smalltalk Examples/Benchmarks/BenchmarkHarness.som Bounce 1000 0 1000

and

./graal.sh -cp Smalltalk:Examples/Benchmarks/Richards/ Examples/Benchmarks/BenchmarkHarness.som Richards 1000 0 100

PS:

To checkout the relevant branch of TruffleSOM (graal.sh will need you to set $GRAAL_HOME to work out of the box):

git clone --recursive -b exp/greater-than https://github.com/SOM-st/TruffleSOM.git 
ant jar
./graal.sh -cp Smalltalk Examples/Benchmarks/BenchmarkHarness.som GreaterThan 1000 0 1000


The Truffle patch is at [2], and the relevant code can be checked out with:
 git clone -b master https://github.com/smarr/graal.git
