Bug ID: 52328
Summary: Poor diagnostic for missing semicolon before case
label
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: h...@chromium.org
CC: llvm-bugs@lists.llvm.org, neeil...@live.com,

$ cat /tmp/a.c
void f(int x) {
switch (x) {
case 0: return // <-- Missing semicolon.
case 1: return;
}
}
$ clang -c /tmp/a.c
/tmp/a.c:4:10: error: expected expression
case 1: return;
^
1 error generated.
When the return statement has an expression, we get it right:
$ cat /tmp/b.c
int f(int x) {
switch (x) {
case 0: return 1 // <-- Missing semicolon.
case 1: return 2;
}
}
$ clang -c /tmp/b.c
/tmp/b.c:3:26: error: expected ';' after return statement
case 0: return 1 // <-- Missing semicolon.
^
;
1 error generated.
