2009-11-11Reimplement out-of-bound array access checker with the new checker interface.Zhongxing Xu
Now only one test case is XFAIL'ed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86834 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-11CastToStructChecker: use 'isStructureType()' instead of 'isRecordType()' to ↵Ted Kremenek
determine if a pointer is casted to a struct pointer. This fixes an observed false positive when a value is casted to a union. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86813 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-11And now a test fix in +Asserts mode, which I broke.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86801 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-11Fix some tests in -Asserts mode.Daniel Dunbar
- FileCheck is a *huuuuge* improvement here. - Still feels like we could use a better tool for this though, either teach llvm-dis to spit out the FileCheck syntax, or provide another tool to turn a .ll into a "matchable" input. - Also on my Christmas list is better FileCheck diagnostics with missing variables or mismatches. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86800 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-11Apparently the following idiom is specifically encouraged:John McCall
if (self = [super init]) Recognize it and only warn if -Wparentheses is explicitly enabled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86790 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-11Introduce a new representation for template templateDouglas Gregor
parameters. Rather than storing them as either declarations (for the non-dependent case) or expressions (for the dependent case), we now (always) store them as TemplateNames. The primary change here is to add a new kind of TemplateArgument, which stores a TemplateName. However, making that change ripples to every switch on a TemplateArgument's kind, also affecting TemplateArgumentLocInfo/TemplateArgumentLoc, default template arguments for template template parameters, type-checking of template template arguments, etc. This change is light on testing. It should fix several pre-existing problems with template template parameters, such as: - the inability to use dependent template names as template template arguments - template template parameter default arguments cannot be instantiation However, there are enough pieces missing that more implementation is required before we can adequately test template template parameters. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86777 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-10Make a somewhat more convincing test case for unqualified lookup throughJohn McCall
using directives, and fix a bug thereby exposed: since we're playing tricks with pointers, we need to make certain we're always using the same pointers for things. Also tweak an existing error message. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86679 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-10Fix unqualified lookup through using directives.John McCall
This is a pretty minimal test case; I'll make a better one later. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86669 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-10When trying to assign a regular string literal to an Objective-C 'id' type ↵Anders Carlsson
or a pointer to an NSString, emit a code insertion hint that turns it into an Objective-C string. For example: @class NSString; @interface Test + (void)test:(NSString *)string; @end void g(NSString *a); void f() { NSString *a = "Foo"; g("Foo"); [Test test:"Foo"]; } will produce t.m:10:17: warning: incompatible pointer types initializing 'char [4]', expected 'NSString *' NSString *a = "Foo"; ^~~~~ @ t.m:11:5: warning: incompatible pointer types passing 'char [4]', expected 'NSString *' g("Foo"); ^~~~~ @ t.m:12:14: warning: incompatible pointer types sending 'char [4]', expected 'NSString *' [Test test:"Foo"]; ^~~~~ @ 3 diagnostics generated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86665 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-10If a function with a default argument is redefined and the new function also ↵Anders Carlsson
has a defualt argument then add a fixit hint that removes the default argument. Fixes PR5444. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86659 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-10Refine PointerSubChecker: compare the base region instead of the original Zhongxing Xu

2009-11-09Changed error for nested type qualifier mismatch toFariborz Jahanian
warning, to match gcc. It used to be warning, so better keep it a warning (it broke a certain project). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86597 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-09Make sure that we look into nested, transparent declaration contextsDouglas Gregor
when looking for a name within a given DeclContext. Now enumerators will show up in code-completion results. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86591 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-09Add additional note to mark the cause of synthesized constructors. MarkEli Friedman
declaration invalid if the constructor can't be properly built. Addresses remaining review comments from Fariborz for r86500. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86579 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-09Improve instantiation of default template arguments for nestedDouglas Gregor
templates. The instantiation of these default arguments must be (and now, is) delayed until the template argument is actually used, at which point we substitute all levels of template arguments concurrently. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86578 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-09Add support for cdecl attribute. (As far as I know, it doesn't affect CodeGenEli Friedman
unless we start implementing command-line switches which override the default calling convention, so the effect is mostly to silence unknown attribute warnings.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86571 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86504 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-09Unify the codepaths used to verify base and member initializers for explicitlyEli Friedman
and implicitly defined constructors. This has a number of benefits: 1. Less code. 2. Explicit and implicit constructors get the same diagnostics. 3. The AST explicitly contains constructor calls from implicit default constructors. This allows handing some cases that previously weren't handled correctly in IRGen without any additional code. Specifically, implicit default constructors containing calls to constructors with default arguments are now handled correctly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86500 91177308-0d34-0410-b5e6-96231b3b80d8
