This patch was submitted to the list for review and didn't receive a LGTM.
(In fact one explicit objection and one query were raised.)
This reverts commit r197295.
llvm-svn: 197299
Previously, a line like
// expected-error-re {{foo}}
treats the entirety of foo as a regex. This is inconvenient when matching type
names containing regex characters. For example, to match
"void *(class test8::A::*)(void)" inside such a regex, one would have to type
"void \*\(class test8::A::\*\)\(void\)".
This patch changes the semantics of expected-error-re to only treat the parts
of the directive wrapped in double curly braces as regexes. This avoids the
escaping problem and leads to nicer patterns for those cases; see e.g. the
change to test/Sema/format-strings-scanf.c.
(The balanced search for closing }} of a directive also makes us handle the
full directive in test\SemaCXX\constexpr-printing.cpp:41 and :53.)

- format specifies type 'wchar_t **' (aka 'int **') but the argument has type 'float *'
- format specifies type 'wchar_t **' (aka 'unsigned short **') but the argument has type 'float *'

This is useful for example for %n in printf, which expects
a pointer to int with the same logic for checking as %d
would have in scanf.

This is in preparation for being able to warn about 'q' and other
non-standard format string features.
It also allows us to print its name correctly.

string is part of the function call, then there is no difference. If the
format string is not, the warning will point to the call site and a note
will point to where the format string is.
Fix-it hints for strings are moved to the note if a note is emitted. This will
prevent changes to format strings that may be used in multiple places.
