Detailed Description
The comma transformation is aimed to handle the case such as
k = (i++, j++)
in the code.
This type of operator is not supported in Verilog and thus we need to break
the code into sequence of code such as:
i++
k = j++
Note: k = j++ will be handled by another pass that gets j and j++ correctly
To handle this, we break a hBinop , [ lhs rhs ] node into two.
lhs will be appended to the parent and rhs remains
