gcc warning: control reaches end of non-void function
Summary
The GCC compiler generates a warning: warning: control reaches end of non-void function [-Wreturn-type]
Steps and/or TTCN-3 code to reproduce
module proba{
type enumerated t_e {I,O}
function f1(in t_e a) return integer {
select(a){
case (I) {
return 1
}
case else {
return 2
}
}
}
}What is the current bug behavior?
g++ -c -DLINUX -I/home/ethgasz/TTCNv3/include -Wall -o proba.o proba.cc
proba.cc: In function ‘INTEGER proba::f1(const proba::t__e&)’:
proba.cc:665:1: warning: control reaches end of non-void function [-Wreturn-type]
}
^What is the expected correct behavior?
No warning
Possible fixes
Do not generate the unnecessary goto and label statements
