Bug ID: 37117
Summary: -Wunreachable-code warning not issued when a macro is
used
Product: clang
Version: 6.0
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Reported by Martin Galvin on cfe-dev:
This code triggers the warning:
int main()
{
return 0;
int a = 42;
}
while this doesn't:
#define A 42
int main()
{
return 0;
int a = A;
}
This happens on clang++-6.0. I'm not using any options other than
-Wunreachable-code
