Bug #: 12828
Summary: Fixit for variable definition after label
Product: clang
Version: trunk
Platform: All
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P
Component: -New Bugs
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
The following code is a syntax error in C99 (or at least, clang and gcc agree
that it's a syntax error):
---
int main() {
foo:
int x = 0;
return x;
}
---
It can be fixed by putting an empty statement after the label:
---
int main() {
foo:;
int x = 0;
return x;
}
---
However, the error given by clang isn't very descriptive:
---
def-after-label.c:3:5: error: expected expression
int x = 0;
---
A more descriptive error message noting that a label may not be followed
immediately by a variable definition and a fixit inserting the empty statement
would be more helpful.
