Example 1 with ArrayTypeDef

use of com.rockwellcollins.atc.agree.AgreeTypeSystem.ArrayTypeDef in project AGREE by loonwerks.

the class AgreeValidator method checkArraySubExpr.

@Check(CheckType.FAST)
public void checkArraySubExpr(ArraySubExpr asub) {
    Expr arrExp = asub.getExpr();
    checkTypeExists(arrExp);
    TypeDef arrType = AgreeTypeSystem.infer(arrExp);
    Expr index = asub.getIndex();
    checkTypeExists(index);
    TypeDef indexType = AgreeTypeSystem.infer(index);
    if (!AgreeTypeSystem.typesEqual(indexType, AgreeTypeSystem.Prim.IntTypeDef)) {
        error(index, "index must be an int");
    }
    if (arrType instanceof ArrayTypeDef) {
        ArrayTypeDef arrayTypeDef = (ArrayTypeDef) arrType;
        int arraySize = arrayTypeDef.size;
        BigInteger indexValue = evaluateIndexExpr(index);
        if (indexValue != null) {
            if (!(indexValue.compareTo(BigInteger.ONE) >= 0 && indexValue.compareTo(BigInteger.valueOf(arraySize)) <= 0)) {
                error(index, "Index value " + indexValue + " is out of array bounds [1 .. " + arraySize + "]");
            }
        } else {
            warning(index, "Could not statically compute array index value");
        }
    } else {
        error(arrExp, "expression must evaluate to an array");
    }
}

Example 2 with ArrayTypeDef

use of com.rockwellcollins.atc.agree.AgreeTypeSystem.ArrayTypeDef in project AGREE by loonwerks.

the class AgreeValidator method checkArrayUpdateExpr.

@Check(CheckType.FAST)
public void checkArrayUpdateExpr(ArrayUpdateExpr arrup) {
    List<Expr> exprs = arrup.getValueExprs();
    Expr arrExpr = arrup.getArray();
    checkTypeExists(arrExpr);
    TypeDef arrType = AgreeTypeSystem.infer(arrExpr);
    if (arrType instanceof ArrayTypeDef) {
        TypeDef t = ((ArrayTypeDef) arrType).stemType;
        TypeDef elmType = AgreeTypeSystem.infer(exprs.get(0));
        if (!AgreeTypeSystem.typesEqual(elmType, t)) {
            error(exprs.get(0), "type of element must be " + nameOfTypeDef(elmType) + ", but has type " + nameOfTypeDef(t));
        }
    } else {
        error(arrExpr, "expression must evaluate to an array");
    }
