Description
The following generates invalid code:
pragma Strict import QtQml QtObject { function absMinusOne(amount: real) : real { if (amount < 0) amount = -amount; return amount - 1; } property real a: absMinusOne(-5) property real b: absMinusOne(10) }
Produces -6 for property 'a'. In the "amount - 1" expression it doesn't use the register it stores the new amount in, but rather the original argument.
