----------------------------------
Summary: Implicit returns of transformed binary expressions do not
have line numbers when statically compiled
Key: GROOVY-7870
URL: https://issues.apache.org/jira/browse/GROOVY-7870
Project: Groovy
Issue Type: Bug
Components: Static compilation
Affects Versions: 2.4.7
Reporter: Shil Sinha
If certain transformed binary expressions (<=>, ==, <<, >>, >>>) are
implicitly returned, their line numbers are not reported. Example:
{code}
@groovy.transform.CompileStatic
def test() {
def l = []
l << 3
}
{code}
The code is compiled to the following bytecode (as seen using GroovyConsole):
{code}
public test()Ljava/lang/Object;
L0
LINENUMBER 3 L0
ICONST_0
ANEWARRAY java/lang/Object
INVOKESTATIC org/codehaus/groovy/runtime/ScriptBytecodeAdapter.createList
([Ljava/lang/Object;)Ljava/util/List;
ASTORE 1
L1
ALOAD 1
POP
ALOAD 1
ICONST_3
INVOKESTATIC java/lang/Integer.valueOf (I)Ljava/lang/Integer;
INVOKESTATIC org/codehaus/groovy/runtime/DefaultGroovyMethods.leftShift
(Ljava/util/List;Ljava/lang/Object;)Ljava/util/List;
ARETURN
L2
ACONST_NULL
ARETURN
LOCALVARIABLE this Lscript1466525199339; L0 L2 0
LOCALVARIABLE l Ljava/util/List; L1 L2 1
MAXSTACK = 2
MAXLOCALS = 2
{code}
There is no line number corresponding to L2, which includes the leftShift call
(should be line number 4.)
