constant, also consider whether it's a class type that has any mutable fields. If so, it can't be a global constant. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131276 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-12LLVM doesn't always optimize away the four loads from this:Bill Wendling
(__m128){ p[0], p[1], p[2], p[3] } which produces really bad code. This could be done in instcombine, but it's probably better to do it in the front-end instead. <rdar://problem/9424836> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131237 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-08Don't emit complete constructors for abstract classes. Also, don't emitAnders Carlsson
complete destructors for abstract classes unless the destructor is virtual and thus needs to be in the vtable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131068 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-07In C++, allow us to emit a global as 'constant' even if it has classDouglas Gregor
type, so long as it is known to have a constant initializer and the class type is a POD class. Fixes <rdar://problem/9306265>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131060 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-06Modify some deleted function methods to better reflect reality:Sean Hunt
- New isDefined() function checks for deletedness - isThisDeclarationADefinition checks for deletedness - New doesThisDeclarationHaveABody() does what isThisDeclarationADefinition() used to do - The IsDeleted bit is not propagated across redeclarations - isDeleted() now checks the canoncial declaration - New isDeletedAsWritten() does what it says on the tin. - isUserProvided() now correct (thanks Richard!) This fixes the bug that we weren't catching void foo() = delete; void foo() {} as being a redefinition. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131013 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-06Don't emit nsw flags for vector operations; there's basically no benefit, ↵Eli Friedman
and a lot of downside (like PR9850, which is about clang's xmmintrin.h making an unexpected transformation on an expression involving _mm_add_epi32). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131000 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-06Add an implementation of thunks for varargs methods. The implementation is ↵Eli Friedman
a bit messy, but it is correct as long as the method in question doesn't use indirect gotos. A couple of possible alternative implementations are outlined in FIXME's in this patch. rdar://problem/8077308 . git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130993 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-06Reset the emitted initializers.Axel Naumann

2011-05-04Pack ivar offsets together.Bill Wendling
Ivar offsets for synthesized ivars are wrong, which could end up with a large number of dirty pages because of ivar fixups at runtime. When we pack all of the synthesized ivars into the same section, it limits the number of dirty pages created. Place them in the "__DATA,__objc_ivar" section. <rdar://problem/9374905> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130870 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-03Ensure that destructors are properly inovked when an exception leavesSean Hunt
the body of a delegating constructor call. This means that the delegating constructor implementation should be complete and correct, though there are some rough edges (diagnostic quality with the cycle detection and using a deleted destructor). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130803 91177308-0d34-0410-b5e6-96231b3b80d8

rdar://problem/8139919 . This shouldn't make much of a difference at -O3, but should substantially reduce the number of generated memcpy's at -O0. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130717 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-02Remove unused variable spotted by GCC.Nick Lewycky
Devang, can we remove this call entirely? If I try that, "make check" passes but the call has a side-effect of ensuring that the block's context exists in the debug info. getContextDescriptor() is used in a void context for that side- effect elsewhere in this file. Please take a look! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130679 91177308-0d34-0410-b5e6-96231b3b80d8

As far as I know, this implementation is complete but might be missing a few optimizations. Exceptions and virtual bases are handled correctly.
