# How shalt thou compile, with patience and practice
|
|
1. Compile thy code
|
|
`javac -cp .:javaparser-1.0.0.jar:./lib/jgrapht-core-1.5.2.jar:./lib/jgrapht-io-1.5.2.jar:./lib/apfloat-1.10.1.jar:./lib/jheaps-0.14.jar CFGGraph/*.java LCA_JP1_0_0.java`
|
|
|
|
`javac -cp .:javaparser-1.0.0.jar:./lib/* CFGGraph/*.java LCA_JP1_0_0.java`
|
|
2. Now move forth to victory
|
|
`java -cp .:javaparser-1.0.0.jar:./lib/jgrapht-core-1.5.2.jar:./lib/jgrapht-io-1.5.2.jar:./lib/ apfloat-1.10.1.jar:./lib/jheaps-0.14.jar LCA_JP1_0_0 Test.java`
|
|
|
|
`java -cp .:javaparser-1.0.0.jar:./lib/* LCA_JP1_0_0 Test.java`
|
|
3. PS: On Windows, replace `:` with `;` and `/` with `\` in paths
|
|
|
|
|
|
Node 1 (ENTRY): Created FIRST, so it gets ID = 1
|
|
Node 2 (EXIT): Created SECOND, so it gets ID = 2
|
|
Then we build the rest of the method body starting from node 3
|
|
|
|
Why we need them:
|
|
ENTRY marks where the method starts (before any code executes)
|
|
EXIT marks where the method ends (after return statements)
|
|
Helps with analysis - clear start/end points for control flow
|
|
```java
|
|
if (val == 5) { // node 8
|
|
val = 6; // node 10
|
|
} // node 9: MERGE_IF
|
|
```
|
|
**Node 9 (MERGE_IF) → edge 14**:
|
|
- Node 9 is where the FIRST if statement merges (after `val = 6;`)
|
|
- After the merge, control flow continues to the NEXT statement
