Detailed Description
Conversion of fir.select_case
The fir.select_case operation is converted to a if-then-else ladder. Depending on the case condition type, one or several comparison and conditional branching can be generated.
A point value case such as case(4), a lower bound case such as case(5:) or an upper bound case such as case(:3) are converted to a simple comparison between the selector value and the constant value in the case. The block associated with the case condition is then executed if the comparison succeed otherwise it branch to the next block with the comparison for the next case conditon.
A closed interval case condition such as case(7:10) is converted with a first comparison and conditional branching for the lower bound. If successful, it branch to a second block with the comparison for the upper bound in the same case condition.
TODO: lowering of CHARACTER type cases is not handled yet.
