Rafael Espindola b6cc74c809 Small refactoring so that only one of the mergeVisibility/mergeLinkage functions 
calls setVisibility/setLinkage.

No functionality change.

used anywhere.

Douglas Gregor da38930cf3 Implement declaration merging for Objective-C protocols across 
multiple, disjoint modules. There is far too much duplicating with the
ObjCInterfaceDecl case here, which I'll eliminate shortly.

Douglas Gregor f610267581 Eliminate ObjCForwardProtocolDecl, which is redundant now that 
ObjCProtocolDecl modules forward declarations properly.

llvm-svn: 147415
 2012-01-01 21:23:57 +00:00
Douglas Gregor c51118238c Don't bother rewriting an Objective-C class or protocol declaration to the module file when we've merely added a definition 
llvm-svn: 147414
 2012-01-01 20:35:33 +00:00
Douglas Gregor 42ff1bb922 Eliminate ASTMutationListener::UpdatedAttributeList, which is no 
longer needed now that we aren't back-patching ObjCProtocolDecls.

llvm-svn: 147413
 2012-01-01 20:33:24 +00:00
Douglas Gregor 32c1757730 Wire up redeclaration chains for Objective-C protocols, so that both 
forward declarations and definitions of an Objective-C protocol are
represented within a single chain of ObjCProtocolDecls.

llvm-svn: 147412
 2012-01-01 20:30:41 +00:00
Douglas Gregor a715bfff98 Introduce the core infrastructure needed to model redeclaration chains 
for Objective-C protocols, including:
  - Using the first declaration as the canonical declaration
  - Using the definition as the primary DeclContext
  - Making sure that all declarations have a pointer to the definition
  data, and that we know which declaration is the definition
  - Serialization support for redeclaration chains and for adding
  definitions to already-serialized declarations.

However, note that we're not taking advantage of much of this code
yet, because we're still re-using ObjCProtocolDecls.

llvm-svn: 147410
 2012-01-01 19:51:50 +00:00
Douglas Gregor e6e48b1490 Move the data that corresponds to the definition of a protocol into a 
separately-allocated DefinitionData structure. Introduce various
functions that will help with the separation of declarations from
definitions (isThisDeclarationADefinition(), hasDefinition(),
getDefinition()).

llvm-svn: 147408

Rafael Espindola 01fb1135d6 Use hasSameType. 
llvm-svn: 147407
 2012-01-01 18:36:59 +00:00
Douglas Gregor 33b2429bf3 Use declaresSameEntity() when comparing ObjCProtocolDecls, and 
getCanonicalDecl() when putting ObjCProtocolDecls into a set. This is
groundwork for making ObjCProtocolDecl redeclarable.

Rafael Espindola 0f960a0a5a Consider visibility attributes in namespaces as being explicit. I.e., they 
take precedence over command line options. Fixes PR10113.

NAKAMURA Takumi 1154e75c7c clang/unittests/Basic/SourceManagerTest.cpp: Fixup corresponding to r147387. 
llvm-svn: 147388
 2011-12-31 04:25:56 +00:00
Douglas Gregor 1fb5c3a63a Implement support for module requirements, which indicate the language 
features needed for a particular module to be available. This allows
mixed-language modules, where certain headers only work under some
language variants (e.g., in C++, std.tuple might only be available in
C++11 mode).

llvm-svn: 147387
 2011-12-31 04:05:44 +00:00
NAKAMURA Takumi 84a5dfdf72 Split out clang/test/Driver/debug-options-as.c from debug-options.c, and mark it as XFAIL: mingw32. 
Mingw32 target has not supported integrated-as yet.

Richard Smith fddd384b73 Unrevert r147271, reverted in r147361. 
Also temporarily remove the assumption from IR gen that we can emit IR for every
constant we can fold, since it isn't currently true in C++11, to fix PR11676.

Original comment from r147271:

constexpr: perform zero-initialization prior to / instead of performing a
constructor call when appropriate. Thanks to Eli for spotting this.

Craig Topper ba418d8e91 Remove an accidental change from r147370. Would only break if the new fma4 flag was used. 
llvm-svn: 147371
 2011-12-30 07:35:49 +00:00
Craig Topper ffdb46ceef Add FMA4 feature flag. Intrinsics coming soon. Also make sse4a feature flag imply sse3. Matches gcc behavior.

Richard Smith e434590bd9 Change the diagnostics which said 'accepted as an extension' to instead say 
'is an extension'. The former is inappropriate and confusing when building with
-Werror/-pedantic-errors.

Craig Topper 1de8348db7 Add popcnt feature flag to match gcc. This flag is implied when sse42 is enabled, but can be disabled separately. Move popcnt intrinsics to popcntintrin.h to match gcc.

Benjamin Kramer cf5014771d Add a target hook for FLT_EVAL_METHOD and use it to set the value on x86 with sse disabled. 
x87 math evaluates everything with 80 bits precision, so we have to set FLT_EVAL_METHOD
to "2".

llvm-svn: 147311
 2011-12-28 15:47:06 +00:00
Hans Wennborg e5f554ac48 Support the 'a' scanf length modifier as an extension in C++. 
It should not be supported in C++11, since that uses the C99 standard
library, in which 'a' is a format specifier.

Zhongxing Xu 86a68d078c Enable the user to control whether CXXConstructExpr will be added as a 
block-level expr. Currently CXXConstructExpr is always added as a block-level
expr. This caused two problems for the analyzer (and potentially for the
CFG-based codegen).
1. We have no way to know whether a ctor call is base or complete.
2. We have no way to know the destination object being contructed.

Douglas Gregor deafd0b2a4 Eliminate ObjCClassDecl, which is redundant now that ObjCInterfaceDecl

Objective-C class.

Rafael Espindola 0b79046c5c Fix the visibility of methods of explicit template instantiation definition
