Subject: [Cocci] Missing support in SmPL for wide char character constants and string literals
Date: Wed, 2 Oct 2019 23:05:03 +0200	[thread overview]
Message-ID: <c0801ee0-c227-5d9d-50ff-3ad872621808@mykolab.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 366 bytes --]

Hello!

SmPL doesn't support the character constants of the form:
u'c', U'c', L'c'

nor the string literals of the form:
u8"", u"", U"", L""

A test case is attached as a patch for the coccinelle tests.

minus: parse error:
  File "tests/wchar.cocci", line 8, column 22, charpos = 106
  around = ''',
  whole content = - char16_t zero = u'\0';


thanks
bye
	michael
