| 1 | * first jikes-native is compiled | ||
| 2 | * a Java 1.4-capable compiler that does not need a runtime or | ||
| 3 | (strictly) a class library to work | ||
| 4 | * jikes-initial-native is a wrapper around it | ||
| 5 | |||
| 6 | * with this compiler we compile the initial (preliminary) | ||
| 7 | runtime (package virtual/java-initial-native) | ||
| 8 | * virtual/java-initial-native can be: cacao-initial-native (0.98) | ||
| 9 | or jamvm-initial-native (1.4.5) | ||
| 10 | * cacao is preferred, as it has a JIT, but doesn't compile | ||
| 11 | on all hosts | ||
| 12 | * cacao-initial-native and jamvm-initial-native both need | ||
| 13 | classpath-initial-native (0.93) and jikes-initial-native | ||
| 14 | |||
| 15 | * now libecj-bootstrap-native is built | ||
| 16 | * this needs jikes-initial-native virtual/java-initial-native | ||
| 17 | * now ecj-initial is built | ||
| 18 | * this needs libecj-bootstrap-native and | ||
| 19 | virtual/java-initial-native during runtime | ||
| 20 | * at that point we have a 1.5-capable compiler (ecj-initial) | ||
| 21 | running on a Java 1.4 compatible VM (cacao-inital-native | ||
| 22 | or jamvm-initial-native) | ||
| 23 | |||
| 24 | * with this compiler (ecj-initial), we compile the final runtime | ||
| 25 | and compiler (virtual/java-native and virtual/javac-native) | ||
| 26 | * virtual/java-native can be: cacao-native (1.6.1) or | ||
| 27 | jamvm-native (2.0.0~pre) | ||
| 28 | * cacao vs jamvm as above | ||
| 29 | * cacao-native and jamvm-native both need | ||
| 30 | classpath-initial-native (0.93) and classpath-native (0.99) | ||
| 31 | and ecj-initial-native and virtual/java-initial-native | ||
| 32 | * virtual/javac-native can be: ecj-bootstrap-native | ||
| 33 | * ecj-bootstrap-native needs libecj-bootstrap-native | ||
| 34 | and virtual/java-native | ||
| 35 | * at that point we have a 1.5-capable compiler (ecj-bootstrap-native) | ||
| 36 | running on a Java 1.5 compatible VN (cacao-native or | ||
