[Transformers] Re: Adjacent string literals

Olivier found out the following fact:

As stated in sections 2.1 and 2.13.4 of the C++ standard, adjacent string literals must be concatenated during the translation phase.

const char* s = "bon" "jour." "\n";

is equivalent to:

const char* s = "bonjour.\n";

Here is the difference in the AST: StringLiteral(STRING-LITERAL("\"bon\" \"jour.\" \"\\n\"")) vs StringLiteral(STRING-LITERAL("\"bonjour.\\n\""))

Is it parse-cxx job to perform this concatenation, using a desugaring filter?

No. We can stay with it. It is simple enough. -- Valentin David valentin@lrde.epita.fr
