2010-02-13Emit the 'alignstack' LLVM function attribute when we encounter a functionCharles Davis
marked 'force_align_arg_pointer'. Almost there; now all I need to do is finish up the backend. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96100 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-13Use a different name for this iterator. MSVC and clang++ didn't like "I" in ↵Benjamin Kramer
the same scope twice. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96086 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-13Switch the standard DeclarationName comparator to be a tri-valued comparator.John McCall
Use that while fixing a nasty misuse of qsort in vtable codegen which, somehow, has not actually caused a crash. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96062 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-12Keep track of whether a final overrider needs a return type adjustment.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95985 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-12Keep track of the address points for all primary bases, and add the ability ↵Anders Carlsson
to dump multiple address points for a single offset. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95970 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-12Fix a bug causing an assertion when a covariant return type differed fromJohn McCall
an overriden type only by reduced qualification. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95968 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-11Use getAs instead of cast/dyn_cast on types. (I'm sure Doug will appreciate ↵Anders Carlsson
this). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95911 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-11Move two functions to the top. No functionality change.Anders Carlsson

2010-02-11More vtable layout dumper improvements. Handle destructors, dump the ↵Anders Carlsson
complete function type of the member functions (using PredefinedExpr::ComputeName. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95887 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95874 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-11Check in the beginnings of my new vtable layout builder idea.Anders Carlsson
Right now, it's off by default but can be tested by passing -fdump-vtable-layouts to clang -cc1. This option will cause all vtables that will normally be emitted as part of codegen to also be dumped using the new layout code. I've also added a very simple new vtable layout test case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95865 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-11Remove use of 'std::string' from Attr objects, using instead a byteTed Kremenek
array allocated using the allocator in ASTContext. This addresses these strings getting leaked when using a BumpPtrAllocator (in ASTContext). Fixes: <rdar://problem/7636765> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95853 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-11Eliminate a bunch of unnecessary ASTContexts from members functions ofDouglas Gregor
Decl subclasses. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95841 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-11Eliminate the ASTContext parameter from RecordDecl::getDefinition()Douglas Gregor
and CXXRecordDecl::getDefinition(); it's totally unnecessary. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95836 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-10Generate the objc_read_weak API when callingFariborz Jahanian
a __weak block. Fixes radar 7628591. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95822 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95812 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-10Switch to using -fsjlj-exceptions instead of hard-coding it. Notably, this fixesDaniel Dunbar
calls to the UnwindResumeOrRethrow function for C++/Obj-C exception handling, for Darwin ARM. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95787 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-10Use current location as the location of compiler generated arguments, e.g. ↵Devang Patel
self, _cmd etc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95743 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-09StringRefize two random methods, remove a dead variable and a weird ↵Benjamin Kramer
constructor call. This maybe fixes some of the errors GCC 4.5 gives on this code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95684 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-09Mark implicit "this" argument as an artificial argument.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95673 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-09IRgen: Add CreateMemTemp, for creating an temporary memory object for a ↵Daniel Dunbar
particular type, and flood fill. - CreateMemTemp sets the alignment on the alloca correctly, which fixes a great many places in IRgen where we were doing the wrong thing. - This fixes many many more places than the test case, but my feeling is we need to audit alignment systematically so I'm not inclined to try hard to test the individual fixes in this patch. If this bothers you, patches welcome! PR6240. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95648 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-09Pass inline keyword to optimizer as the new InlineHint function attribute.Jakob Stoklund Olesen
At the moment the inlinehint attribute is ignored by the Inliner unless you pass a -respect-inlinehint option. This will soon be the default. The inlinehint attribute is set if the inline keyword is explicitly specified on any declaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95623 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-08Reapply r95393, without the change to CGExpr. I was wrong in assuming that theDaniel Dunbar
element type always matched the converted LLVM type for ExprType. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95596 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-08Emit global references with constant initializers as constants. Fixes PR5585.John McCall
The standard actually says that such references should have internal linkage, but gcc doesn't do that, so we probably can't get away with it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95577 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-07Make sure to set vtable pointers in the destructors as well.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95525 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-07Use the right type when taking the address of a non-virtual member function ↵Anders Carlsson
pointer. Fixes PR6258. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95524 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-07Use the right linkage for static variables inside C++ inline functions.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95512 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-07Improved handling of the visibility attribute. Declarations now inherit ↵Anders Carlsson
their parent's visibility. (This is kind of a risky change, but I did a self-host build and everything appears to work fine!) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95511 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-06Make EmitStartEHSpec and EmitEndEHSpec return early when exceptions are ↵Anders Carlsson
disabled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95509 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-06Add support for threadsafe statics, and make them the default (matching gcc).Anders Carlsson
Daniel, I'd appreciate a review of the driver/cc1 parts. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95508 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-06Call destructors for constructed bases as well.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95502 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-06If a constructor throws an exception we need to execute the destructors for ↵Anders Carlsson
all fully constructed members. Fixes ctor_dtor_count.cpp in the test suite. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95501 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-06Switch CodeGen's "is this variable declaration a definition?" logicDouglas Gregor
over to VarDecl::isThisDeclarationADefinition(), which handles variables declared with linkage specifications better (among other things). CMake 2.9 (from CVS) now builds with clang++ and is somewhat functional. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95486 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-06Only append 'L' for internal variable declarations, not all declarations. ↵Anders Carlsson
(Found by the mangle checker, yay) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95485 91177308-0d34-0410-b5e6-96231b3b80d8
