Bug ID: 31640
Summary: diagnose_if generates better diagnostics as a warning
Product: clang
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: e...@efcs.ca
CC: dgre...@apple.com, llvm-bugs@lists.llvm.org
Classification: Unclassified
Currently diagnose_if produces entirely different diagnostics when used as an
error instead of a warning. The error diagnostic is equivalent to an
"unavailable(msg)" diagnostic while the warning simply generates "warning:
msg".
I believe the error diagnostic is misleading and should be change to match the
warning diagnostics.
Example:
void foo(int i) __attribute__((diagnose_if(i, "my warning", "warning"))) {}
void foo(long i) {}
void bar(int i) __attribute__((diagnose_if(i, "my error", "error"))) {}
void bar(long i) {}
int main() {
foo(1); // expected-warning {{my warning}}
bar(1); // expected-error {{call to unavailable function 'bar'}}
}
