Richard Smith 8d06f42448 Improve 0-argument -Wvexing-parse diagnostic by adding notes with fix-its: ... - If the declarator is at the start of a line, and the previous line contained another declarator and ended with a comma, then that comma was probably a typo for a semicolon: int n = 0, m = 1, l = 2, // k = 5; myImportantFunctionCall(); // oops! - If removing the parentheses would correctly initialize the object, then produce a note suggesting that fix. - Otherwise, if there is a simple initializer we can suggest which performs value-initialization, then provide a note suggesting a correction to that initializer. Sema::Declarator now tracks the location of the comma prior to the declarator in the declaration, if there is one, to facilitate providing the note. The code to determine an appropriate initializer from the -Wuninitialized warning has been factored out to allow use in both that and -Wvexing-parse. llvm-svn: 148072		2012-01-12 23:53:29 +00:00
