2008-03-05remove the source location arguments to various target query methods.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47954 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-05Remove the first layer of support for "portability" warnings. This is Chris Lattner
theoretically useful, but not useful in practice. It adds a bunch of complexity, and not much value. It's best to nuke it. One big advantage is that it means the target interfaces will soon lose their SLoc arguments and target queries can never emit diagnostics anymore (yay). Removing this also simplifies some of the core preprocessor which should make it slightly faster. Ted, I didn't simplify TripleProcessor, which can now have at most one triple, and can probably just be removed. Please poke at it when you have time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47930 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-26Removed static analysis-specific diagnostics from DiagnosticKinds.def.Ted Kremenek
Use custom diagnostics for static analysis checkers. Added warnings for dereferencing uninitialized values and divide-by-zeroes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47626 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-24Two more Windows-related fixes:Ted Kremenek
- More enum signeness bitfield fixes (MSVC treats enums as signed). - Fixed in Lex/HeaderSearch.cpp an unsafe copy between two HeaderSearch::PerFileInfo entries in a common vector. The copy involved two calls to getFileInfo() within the assignment; these calls could have side-effects that enlarged the internal vector, and with MSVC this would invalidate one of the values in the assignment.

2008-02-11Move Microsoft __declspec hack from the parser to the preprocessor. Since we ↵Steve Naroff
have no plans to actually implement this construct, it is cleaner to limit the change to the preprocessor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46973 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-10Fix PR1999, by emitting a hard error only if an argument declarator is ↵Chris Lattner
completely missing. Otherwise, it is an implicit int case, which is valid in c90 and invalid elsewhere, but accepted as an extension. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46938 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-08A bunch-o changes to fix <rdar://problem/5716046> incomplete implementation ↵Steve Naroff
of ObjC class warning is incomplete As part of this fix, I made a low-level change to the text diagnostics machinery (to basically avoid printing duplicate source lines/carets when you have multiple diagnostics that refer to the same exact place). For now, this only happens with we don't have a source range (could be extended to support source ranges as well). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46897 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-02Cleanup previous patch (based on feedback from Ted).Steve Naroff
Since this behavior is useful for most classes, we might consider adding a simple 3 method class that implements the behavior. Ted said that Boost has such a class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46654 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-25Replace Sema::CheckVariableInitList, CheckConstantInitList, and ↵Steve Naroff
CheckForCharArrayInitializer with CheckInitializerListTypes. The new routine now supports struct/union initializers. This is a modified version of a patch by Eli Friedman. This version passes all of the clang tests and supports vectors:-) Note that Eli and I are still unsatisfied the implementation of CheckInitializerListTypes(). We'd like to find a more elegant implementation. Nevertheless, this is a complex part of the standard (and may be hard to simplify). Since the complexity is localized to this routine, we can iterate without too much disruption:-) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46339 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-17Implement basic overload support via a new builtin, __builtin_overload.Nate Begeman
__builtin_overload takes 2 or more arguments: 0) a non-zero constant-expr for the number of arguments the overloaded functions will take 1) the arguments to pass to the matching overloaded function 2) a list of functions to match. The return type of __builtin_overload is inferred from the function whose args match the types of the arguments passed to the builtin. For example: float a; float sinf(float); int sini(int); float b = __builtin_overload(1, a, sini, sinf); Says that we are overloading functions that take one argument, and trying to pass an argument of the same type as 'a'. sini() does not match since it takes and argument of type int. sinf does match, so at codegen time this will turn into float b = sinf(a); git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46132 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-13Change Sema::CheckAddressOfOperation() to respect C99-only addressof rules.Steve Naroff
Remove diagnostics from Sema::CheckIndirectionOperand(). C89/C99 allow dereferencing an incomplete type. clang appears to be emulating some incorrect gcc behavior (see below). void foo (void) { struct b; struct b* x = 0; struct b* y = &*x; // gcc produces an error ("dereferencing pointer to incomplete type") } With this patch, the above is now allowed.
