https://issues.dlang.org/show_bug.cgi?id=22307 Issue ID: 22307 Summary: importC: unable to parse __builtin_va_arg Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody@puremagic.com Reporter: dave287091@gmail.com Consider the following preprocessed program using varargs. typedef __builtin_va_list va_list; int add_nums(int count, ...) { int result = 0; va_list args; __builtin_va_start(args, count); for (int i = 0; i < count; ++i) { result += __builtin_va_arg(args, int); // Error: expression expected, not `int` } __builtin_va_end(args); return result; } __builtin_va_arg is unusual, looking like a function, but taking a type as the second argument. -- |
