Hi Patrick,
Using the official SableCC 3 version, I get the AST shown below which
seems fine to me. I've attached the Java source code for the Main class
producing this output.
I guess that, if there is a problem, it must be in the alternative
output back-end. Which language are you targeting? I've heard of minor
bugs in the C# target.
Start:
AGrammar:
AProgramHeading:
*TTsm: "TSM :"
ASingleTsmList:
*TTsmId: "{1,1,7}"
*TSemicolon: ";"
AMainStatementPart:
AFullStatement:
*TLabel: "BOUCLE:"
*TConditions: "AL"
AAssignStatement:
AFifoSimpleResultResultDest:
*TFifoSimpleResult: "(F,3,0,1)"
*TEqual: "="
ASourceFifoSimpleLSourceNode:
*TSourceFifoSimple: "r0"
*TOperator: "op1"
ARSourceNode:
ASourceFifoDeepLSourceNode:
*TSourceFifoDeep: "(r1,0)"
*TSemicolon: ";"
AFullStatement:
*TConditions: "AL"
AJumpStatement:
*TJump: "jump"
*TIdentifier: "BOUCLE"
*TSemicolon: ";"
*EOF: ""
Have fun,
Etienne
That is the long part :) Here it is! Thank yo again for the help you
will be able to provide to me :)
