2011-07-23remove unneeded llvm:: namespace qualifiers on some core types now that ↵Chris Lattner
LLVM.h imports them into the clang namespace. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135852 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14Revert r135147 and r135075. The consensus was that this wasn't the right ↵Ted Kremenek
thing to do. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135152 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14Add extra sanity checking in FormatString::matchesType() that we are ↵Ted Kremenek
comparing integers to integers. This happens not to be an issue now, but the extra check helps future proof in case of future refactorings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135147 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14Reapply r135075, but modify format-strings.c and format-strings-fixit.c test ↵Ted Kremenek
cases to be more portable with an explicit target triple. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135134 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14Revert r135075, "format string checking: long and int have the same widths ↵NAKAMURA Takumi
on 32-bit, so we shouldn't warn about using" It fails on freebsd, mingw and msvc10. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135129 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-13format string checking: long and int have the same widths on 32-bit, so we ↵Ted Kremenek
shouldn't warn about using an "int" format specifier with a "long" type in 32-bit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135075 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-13Re-relax conversion specifier checking for printf format strings and ↵Ted Kremenek
conversion specifiers. My recent change was a mistake. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135048 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-13Fix inversion in argument type checking for format strings with conversion ↵Ted Kremenek
specifiers for character types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135046 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-28Revert r133024, "[format strings] correctly suggest correct type for '%@'Daniel Dunbar
specifiers. Fixes <rdar://problem/9607158>." because it causes false positives on some code that uses CF toll free bridging. - I'll let Doug or Ted figure out the right fix here, possibly just to accept any pointer type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134041 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-14[format strings] correctly suggest correct type for '%@' specifiers. Fixes ↵Ted Kremenek
<rdar://problem/9607158>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133024 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-06Don't warn when matching %p to nullptr.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118344 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-24Fix printf format string checking for '%lc' (which expects a wint_t or ↵Ted Kremenek
compatible argument). Fixes PR 7981. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111978 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-27Revert r109428 "Hoist argument type checking into CheckFormatHandler. This ↵Michael J. Spencer
is prep for scanf format" Got errors about ASTContext being undefined with Visual Studio 2010. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109491 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-26Hoist argument type checking into CheckFormatHandler. This is prep for ↵Ted Kremenek
scanf format string argument type checking. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109428 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-20Move 'hasValidLengthModifier' from PrintfFormatSpecifier to FormatSpecifier.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108906 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-16Add most of the boilerplate support for scanf format string checking. This ↵Ted Kremenek
includes handling the parsing of scanf format strings and hooking the checking into Sema. Most of this checking logic piggybacks on what was already there for checking printf format strings, but the checking logic has been refactored to support both. What is left to be done is to support argument type checking in format strings and of course fix the usual tail of bugs that will follow. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108500 91177308-0d34-0410-b5e6-96231b3b80d8
