+ The `emitc.switch` is a control-flow operation that branches to one of
+ the given regions based on the values of the argument and the cases. The
+ argument is always of type opaque or integer (singed or unsigned), excluding i8
+ and i1.
+
+ The operation always has a "default" region and any number of case regions
+ denoted by integer constants. Control-flow transfers to the case region
+ whose constant value equals the value of the argument. If the argument does
+ not equal any of the case values, control-flow transfer to the "default"
+ region.
+
+ The operation does not return any value. Moreover, case regions and
+ default region must be terminated using the `emitc.yield` operation.
+
+ Example:
+
+ ```mlir
+ // Cases with i32 type.
+ %0 = "emitc.variable"(){value = 42 : i32} : () -> i32
+ emitc.switch %0 : i32
+ case 2: {

+ emitc.yield
+ }
+ case 5: {
+ %2 = emitc.call_opaque "func_a" () : () -> i32
+ emitc.yield
+ }
+ default : {
+ %3 = "emitc.variable"(){value = 42.0 : f32} : () -> f32
+ %4 = "emitc.variable"(){value = 42.0 : f32} : () -> f32
+
+ emitc.call_opaque "func2" (%3) : (f32) -> ()
+ emitc.call_opaque "func3" (%3, %4) { args = [1 : index, 0 : index] } : (f32, f32) -> ()
+ emitc.yield
+ }
+ ...
+ // Cases with i16 type.
+ %0 = "emitc.variable"(){value = 42 : i16} : () -> i16
