2012-09-08clang/test/Sema/format-strings-scanf.c: Relax a couple of expressions with ↵NAKAMURA Takumi
expected-warning-re to let matched for Win32 targets. - 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 *' git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163468 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-08Format strings: %Ld isn't available on Darwin or Windows.Jordan Rose
This seems to be a GNU libc extension; we offer a fixit to %lld on these platforms. <rdar://problem/11518237> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163452 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-07Properly check length modfiers for %n in format strings.Hans Wennborg
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161408 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-07Remove ScanfArgType and bake that logic into ArgType.Hans Wennborg
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161407 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-31-Wformat: better handling of qualifiers on pointer argumentsHans Wennborg
Warn about using pointers to const-qualified types as arguments to scanf. Ignore the volatile qualifier when checking if types match. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161052 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-30Make -Wformat check the argument type for %n.Hans Wennborg
This makes Clang check that the corresponding argument for "%n" in a format string is a pointer to int. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160966 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-16Format string analysis: give 'q' its own enumerator.Hans Wennborg
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150697 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-31FormatCheckers should emit all diagnostics using EmitFormatDiagnostic().Jean-Daniel Dupas

2012-01-24Teach scanf/printf checking about '%Ld' and friends (a GNU extension). ↵Ted Kremenek
Fixes PR 9466. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148859 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-20The 'l' length modifier makes sense with the scanlist conversion specifier.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148586 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-20Tighten format string diagnostic and make it a bit clearer (and a bit closer ↵Ted Kremenek
to GCC's). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148579 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-17Treat -Wformat=0 as an alias for -Wformat.Hans Wennborg
Fixes PR9195. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148300 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-12scanf: parse the 'm' length modifier, and check that the right argumentsHans Wennborg
are used with that and the 'a' length modifier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148029 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-12scanf analysis: the 'a' length modifier is valid with a scanlistHans Wennborg
Before r148025 we (accidentally) didn't check whether a length modifier is appropriate for a scanlist, but now we do. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148026 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-12scanf analysis: don't bail out after successful parse of scanlistHans Wennborg
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148025 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146651 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-15Support the 'a' length modifier in scanf format strings as a C90Hans Wennborg
extension. This fixes gcc.dg/format/c90-scanf-3.c and ext-4.c (test for excess errors). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146649 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-12Make fscanf, vscanf, etc. be recognized as scanf-like functions.Hans Wennborg
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146367 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-10Check that arguments to a scanf call match the format specifier,Hans Wennborg
and offer fixits when there is a mismatch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146326 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-28Fix for PR9751 to change the behavior of -Wformat warnings. If the formatRichard Trieu
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143168 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-19Don't warn when a '%%' or '%*d' (scanf) is used in a format string with ↵Ted Kremenek
positional arguments, since these don't actually consume an argument. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108757 91177308-0d34-0410-b5e6-96231b3b80d8
