Bug ID: 18855
Summary: Lexer produces incorrect identifier in user defined
literals using UCNs
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++1y
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
This program:
> unsigned long long
> operator"" _µs(unsigned long long usec) {
> return usec;
> }
int main() { 3_µs; }
produces the error:
> error: no matching literal operator for call to 'operator "" _' with argument
> of type 'unsigned long long' or 'const char *', and no matching literal
> operator template
int main() { 3_µs; }
The error message indicates that the lexer is not correctly tokenizing the user
defined literal, and is truncating the identifier portion of the literal where
the UCN occurs. The same result occurs with the equivalent literal '3_\u00B5s'.
The result of the above program should be that the program calls the function
operator"" _µs with the argument 3ull.
