en Copyright 2015 Java http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/Sema/incompatible-sign.cpp#c6ffe4d7 [clang] Fix message text for `-Wpointer-sign` to account for plain charThe `-Wpointer-sign` warning text is inappropriate for describing theincompatible pointer conversion between plain `char` and explicitly`signed`/`unsigned` `char` (whichever plain `char` has the same rangeas) and vice versa.Specifically, in part, it reads "converts between pointers to integertypes with different sign". This patch changes that portion to readinstead as "converts between pointers to integer types where one is ofthe unique plain 'char' type and the other is not" when one of the typesis plain `char`.C17 subclause 6.5.16.1 indicates that the conversions resulting in`-Wpointer-sign` warnings in assignment-like contexts are constraintviolations. This means that strict conformance requires a diagnostic forthe case where the message text is wrong before this patch. The lack ofan even more specialized warning group is consistent with GCC.Reviewed By: aaron.ballmanDifferential Revision: https://reviews.llvm.org/D93999 List of files: /llvm-project-15.0.7/clang/test/Sema/incompatible-sign.cpp Mon, 11 Jan 2021 23:36:28 +0000 Hubert Tong <hubert.reinterpretcast@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/Sema/incompatible-sign.cpp#f635bcd1 NFC: Pre-commit test: -Wpointer-sign with plain char to [un]signed charAdd tests with bad message text for `-Wpointer-sign` and run them withboth signed and unsigned versions of plain `char`.
