Bug ID: 25834
Summary: Bad error message for extra parens around declaration
inside if
Product: clang
Version: unspecified
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: h...@apple.com
CC: dgre...@apple.com, llvm-bugs@lists.llvm.org
Classification: Unclassified
This code:
extern int foo();
int main(void) {
if ((auto x = foo())) {
return 1;
}
return 0;
}
When compiled with `clang++ -std=c++11` produces the following error messages:
test.cc:5:15: error: expected ')'
if ((auto x = foo())) {
^
test.cc:5:9: note: to match this '('
if ((auto x = foo())) {
^
test.cc:5:25: error: expected expression
if ((auto x = foo())) {
^
2 errors generated.
This is not a great error message. I'd expect something like "declaration with
extraneous parentheses" and a fixit to remove the extra parentheses.
