Summary: extra error message for problems in statement
expressions
Product: clang
Version: trunk
Platform: Macintosh
OS/Version: All
Status: NEW
Severity: normal
Priority: P
Component: Frontend
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Clang is not propagating expression errors for statement expressions so that it
thinks that the expression type is void, which in turn causes an extra error
message to be printed.
Testcase:
$ cat experr.c
float test(int v) {
return ({ int __a = (v); (float)__a/; });
}
$ clang -S experr.c
experr.c:2:39: error: expected expression
return ({ int __a = (v); (float)__a/; });
^
experr.c:2:10: error: returning 'void' from a function with incompatible result
type 'float'
return ({ int __a = (v); (float)__a/; });
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2 errors generated.
That second message ("returning 'void'....") should be suppressed.
