These compile into different code, one gets recognized as a switch and the
other doesn't due to phase ordering issues (PR6212):
int test1(int mainType, int subType) {
if (mainType == 7)
subType = 4;
else if (mainType == 9)
subType = 6;
else if (mainType == 11)
subType = 9;
return subType;
}
int test2(int mainType, int subType) {
if (mainType == 7)
subType = 4;
if (mainType == 9)
subType = 6;
if (mainType == 11)
subType = 9;
return subType;
}
