[PATCH] D124996: [clang][preprocessor] Fix unsigned-ness of utf8 char literals

[Aaron Ballman via Phabricator via cfe-commits]

aaron.ballman added inline comments.


================
Comment at: clang/test/Lexer/utf8-char-literal.cpp:16
 char f = u8'ab'; // expected-error {{Unicode character literals may not contain multiple characters}}
 #elif __STDC_VERSION__ > 202000L
 char a = u8'ñ';      // expected-error {{character too large for enclosing character literal type}}
----------------
I missed this one before. :-(


================
Comment at: clang/test/Lexer/utf8-char-literal.cpp:31
+/// Test u8 char literal preprocessor behavior
+#if __cplusplus > 201402L || __STDC_VERSION__ > 202000L
+#if u8'\xff' != 0xff
----------------
Uh oh.
