TURKEY-VM
Now, turkey-vm has a new implementation SimpleJVM which is based on OpenJDK7
Turkey is a Java Virtual Mechine for GNU classpath 0.0.6.
need: 32bit linux
Getting Started
first, you need add GNUclasspath0.0.6/ into the CLASSPATH like this:
export CLASSPATH=$CLASSPATH:/mnt/hgfs/share/turkey/classpath0.0.6
then, youo need add dll/ into the LD_LIBRARY_PATH like this:
export LD_LIBRARY_PATH=/mnt/hgfs/share/turkey/dll
finally,
cd src
cmake CMakeList.txt
make
This will retrieve the library and compile the turkey into src/.
We supply some file in test/ for test.
./turkey -cp ../test/bin/ Test
will get the result like this
test case1: hello, world
hello,world
test case2: sum
1+2+...+100=5050
test case3: args
VM run 0.054671 seconds
also, you can give static main args
./turkey -cp ../test/bin/ Test arg1 arg2 arg3
you can find all source of test case in test/. All test case(except Test.java) are in miniJava lanuage, and they can compile by tiger-comp^_^
##More About Turkey
Besides run this simple test case, turkey now can run tiger0.0.6.
##Command-line
-cp {path} set class search path
-classpath {path} set classpath
-dump {hash|class} dump turkey status
-opcode <NULL> statistic instrctions
-log {name} log method
-verbose {0|1|2|3} verbose turkey
-trace {name} trace specific method
-dr <NULL> disable resolve
-help <NULL> commandline list
-test <NULL> super test!!
###-opcode
Now, turkey can use -opcode to statistic the frequency for every instrctions and store the result in instruction.txt

###-dr -dr can close the resolve, so we can compare the effect of resolve module.
The result bellow is open resolve(default), run tiger0.0.6 to compile LinkedList.java.
