Make the unused expression warning a bit less aggressive (found in PHP
code).

Switch on SemaInit; this makes some code in SemaDecl dead, but I'll give
it a few days to make sure there aren't any significant regressions.

Remove illegal test.

Add errors for some illegal constructs (specifically, "int a = {{3}};"
and "int a = {};").  I'll adjust the tests in a bit.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51265 91177308-0d34-0410-b5e6-96231b3b80d8

Some more SemaInit cleanup.

Various fixes; solves (almost) all of the test regressions that would be
caused by enabling SemaInit.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51261 91177308-0d34-0410-b5e6-96231b3b80d8

Fix the emission of expressions like char a[10] = "asdf"; previously,
they were causing bad code to be emitted.  There are two fixes here: one
makes sure we emit a string that is long enough, and one makes sure we
properly handle string initialization in init lists.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51259 91177308-0d34-0410-b5e6-96231b3b80d8

Add proper type-checking for pointer additiion; before, we were accepting
addition with a pointer and an integer even when it didn't make sense.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51228 91177308-0d34-0410-b5e6-96231b3b80d8

Fix support for _Bool bitfields. The issue is that the bitfield width
used for _Bool is not the same as the primitive width (which for _Bool
is 1 bit).  The load and store changes add some casts to make the
types consistent.  The EmitLValue changes make sure that the pointer is
of an appropriate type for loading the bitfield.

This isn't perfect, but it's an improvement, and getting everything
right depends on actually laying out structs in an ABI-compliant way.

Micro-optimization when checking for panic functions.

Backout of codegen-based fix to PR2334; this has been fixed differently
at the Sema layer.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51203 91177308-0d34-0410-b5e6-96231b3b80d8

Sema-based fix for PR2334.  The issue is that even if the two sides of
the condidtional have compatible types, they are not necessarily the
same type.  Therefore, we cast to the composite type.  As a hack, for
the moment we assume that the composite type is the type of the
left-hand expression; this isn't correct, but it's good enough for most
purposes.

Partitioned BugTypeCachedLocation::isCached() into two methods: one that accepts and ExplodedNode, and the other that accepts a ProgramPoint.  The default behavior is to cache bug reports by the
location they occur (the end node).  Subclasses can override this behavior by providing a different ProgramPoint.

Minor cleanup to isBuiltinConstantExpr.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51188 91177308-0d34-0410-b5e6-96231b3b80d8

Fixed another regression introduced by r51113 caused by some refactoring
in Sema::CheckFunctionCall:

  http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20080512/005706.html

The bug was that the logic from the helper methods used by CheckFunctionCall
were being inverted (a subtle bug).  This would cause the parser to discard
any valid AST nodes involving several builtins (see patch).

This removes the last regression failure I'm seeing in the test suite: Analysis-Apple/NoReturn.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51168 91177308-0d34-0410-b5e6-96231b3b80d8

Removed bogus "return true" in Expr::isConstantExpr that returned true for all
expressions. This appears to be a regression introduced in r51113 that caused
many test cases to fail (there is still a test case in the Analysis directory
that is failing):

An array of VLAs is a VLA.  Shouldn't make any significant difference at

Implement -rewrite-macros, which is a crazy macro expander that expands
macros but doesn't expand #includes, remove comments, remove #defines
etc.

For example:

----
#include <stdio.h>

#define bbaa
#define funclike(x) x "a" x "b" x

bbaa  bbaa

#if 1
funclike("gar")
foo /*blah*/  bar
bar
#endif

#if 0
funclike()
#endif
----

rewrites to:

----
#include <stdio.h>

#define bbaa
#define funclike(x) x "a" x "b" x

/*bbaa  bbaa*/

#if 1
 "gar" "a" "gar" "b" "gar"/*funclike*//*("gar")*/
foo /*blah*/  bar
bar
#endif

#if 0
/*funclike()*/
#endif

Fix <rdar://problem/5924225> clang ObjC rewriter: objc_exception_throw declaration in preamble does not match objc/objc-exception.h.

DO NOT pre-defined __OBJC2__. The __OBJC2__ macro should only be defined when targeting the new, Apple 2.0 *runtime ABI*. It is not intended to be used to #ifdef ObjC 2.0 langauge features. This is unfortunate (given it's name). In a perfect world, this defined would be named __OBJC2_RUNTIME_ABI__. Oh well.

Handle all attributes on a parameter

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50903 91177308-0d34-0410-b5e6-96231b3b80d8

Extend vector member references to include {.hi, .lo, .e, .o} which return a
vector of the same element type and half the width, with the high, low, even,
and odd elements respectively.

Allow member references to member references, so that .hi.hi gives you the high
quarter of a vector.  This is fairly convenient syntax for some insert/extract
operations.

Remove some unnecessary methods/types in the ExtVectorElementExpr class.

Don't call into objc front-end when not parsing objc code.  This avoids
crashes because objc types aren't set up right.

Added initial support for supporting __NSString__ in attribute "format".

Added -g command line options to clang for generating source level debug information. This patch currently enables generation of line number debug information (stoppoints) and region begin/end debug information. The new files CGDebugInfo.h and CGDebugInfo.cpp implements the debug info manager class CGDebugInfo.
