Do you have a suggestion for what lexing > tests to enable the constant interpreter in? I think good candidates are Lexer/char-escapes.c Lexer/char-escapes-delimited.c Lexer/char-literal.cpp CHANGES SINCE LAST ACTION https://reviews.llvm.org/D135366/new/ https://reviews.llvm.org/D135366 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
