Add a builtin. Fixes <rdar://problem/5982037> clang on xcode: error: incompatible operand types ('int' and 'char *').

llvm-svn: 51908

Change Expr::isIntegerConstantExpr() to allow for pointer types (for GCC compatibility). Note FIXME.

Fix <rdar://problem/5977870> clang on xcode: error: arrays with static storage duration must have constant integer length

llvm-svn: 51907

Allow implicit pointer/int conversions on ObjCQualifiedIdTypes in Sema::CheckCompareOperands() and Sema::CheckAssignmentConstraints().

Fixes <rdar://problem/5980804> clang on xcode: error: incompatible type sending 'id<XDUMLType>', expected 'NSCellType'.

Fixes part of <rdar://problem/5980829> clang on xcode: used type 'NSRange' where arithmetic or pointer type is required.

much closer to passing the gcc struct layout tests.

It might be possible to refactor this a bit, but I'm not sure there's 
actually enough common code for that to be useful.

To get the calling convention completely correct, a bit of 
platform-specific code is necessary even for x86-Linux. On x86-Linux, the
alignment of function parameters is extremely strange; as far as I can tell,
it's always 4 except for SSE vectors or structs containing SSE vectors.  I'm 
continuing to investigate this.

This eliminates a bogus warning identified in the test below.

This fixes <rdar://problem/5968256> clang on xcode: error: incompatible type initializing 'NSObject<XCSelectionSource> *', expected 'id<NSObject,XCSelectionSource>'

llvm-svn: 51832

Add some more test cases that demonstrate clang is a bit stricter than GCC. These can be fixed lazily if they become a problem.

llvm-svn: 51830

Teach Sema::CheckConditionalOperands() to check for ObjCQualifiedIdType's. This fixes a bogus error.

TranslationUnit object instead of an ASTContext. By default it calls
Initialize(ASTConstext& Context) (to match with the current interface used by
most ASTConsumers).

Modified the ObjC-Rewriter to use InitializeTU, and to tell the TranslationUnit
to not free its Decls.  This is a workaround for: <rdar://problem/5966749>

llvm-svn: 51825

Some fancy footwork to accommodate embedded preprocessor directives within an interface.

llvm-svn: 51815

This fix involved tightening up needToScanForQualifiers(), which predated ObjCQualifiedIdType.
It also includes a minor tweak to the code that searches for the beginning of the qualified type. If the AST contained the correct beginning of the declaration (i.e. the beginning of the declaration specifiers), this code would be more robust. Since it doesn't, we apply an adhoc heuristic. Note that DeclSpec contains this info...we just don't propagate it to the AST (at present).

llvm-svn: 51812

Hack RewriteObjC::RewriteObjCStringLiteral() to include the filename in the generated code (replacing any non-alphanumeric characters with "_"). This allows header files to contain ObjCStringLiterals.

Teach Expr::isLvalue() about ObjC properties. For now, all properties are writable. Added a FIXME for another day.

types so that they end up the correct size.

llvm-svn: 51787

this does is reconstruct the type for structs and arrays if the type 
wouldn't be compatible otherwise.

The assertion about packing in the struct type reconstruction code 
sucks, but I don't see any obvious way to fix it.  Maybe we need a general
utility method to take a list of types and alignments and try to construct an
unpacked type if possible?

llvm-svn: 51785

associated declaration. This is a prerequisite to handling
general union initializations; for example, an array of unions involving 
pointers has to be turned into a struct because the elements can have 
incompatible types.

I refactored the code a bit to make it more readable; now, the logic for 
definitions is all in EmitGlobalVarInit.

The second parameter for GetAddrOfGlobalVar is now dead; I'll remove it 
separately.

By itself, this patch should not cause any visible changes.

required by the standard (the standard doesn't know anything about 
implicit casts).

Disallow pointers cast to non-integral arithmetic types as constant 
expressions.  This was previously allowed by accident.
