* Fix PR6473.Rafael Espindola2010-03-041-0/+9
| | | | | | | | | Clang's support for weakref is now better than llvm-gcc's :-) We don't introduce a new symbol and we correctly mark undefined references weak only if there is no definition or regular undefined references in the same file. llvm-svn: 97733
* Revert changes r97693, r97700, and r97718.John McCall2010-03-041-7/+1
| | | | | | Our testing framework can't deal with disabled targets yet. llvm-svn: 97719
* Create a TargetMachine whenever we create a CodeGenAction. The codegen ofJohn McCall2010-03-041-1/+7
| | | | | | some builtins will rely on target knowledge. llvm-svn: 97693
* Perform two more constructor/destructor code-size optimizations:John McCall2010-02-231-0/+1
| | | | | | | | | | | | | | | | 1) emit base destructors as aliases to their unique base class destructors under some careful conditions. This is enabled for the same targets that can support complete-to-base aliases, i.e. not darwin. 2) Emit non-variadic complete constructors for classes with no virtual bases as calls to the base constructor. This is enabled on all targets and in theory can trigger in situations that the alias optimization can't (mostly involving virtual bases, mostly not yet supported). These are bundled together because I didn't think it worthwhile to split them, not because they really need to be. llvm-svn: 96842
* Re-introduce the ctor/dtor alias optimization, this time hidden behind aJohn McCall2010-02-191-4/+22
| | | | | | command-line option which defaults off. llvm-svn: 96649
* Revert the ctor/dtor alias optimization for now; the buildbots can detectJohn McCall2010-02-181-22/+4
| | | | | | some failure here that I can't. llvm-svn: 96612
* Emit complete constructors and destructors as aliases to base constructorsJohn McCall2010-02-171-4/+22
| | | | | | | | and destructors when the two entities are semantically identical, i.e. when the class has no virtual base classes. We only do this for linkage types for which aliases are supported, i.e. internal and external, i.e. not linkonce. llvm-svn: 96451

* Generalize target weirdness handling having proper layering in mind:Anton Korobeynikov2010-01-101-0/+3
| | | | | | | | | 1. Add helper class for sema checks for target attributes 2. Add helper class for codegen of target attributes As a proof-of-concept - implement msp430's 'interrupt' attribute. llvm-svn: 93118
* Fix for PR5967: Make const-marking for LLVM globals correct for cases requiringEli Friedman2010-01-081-2/+4
| | | | | | | run-time initialization, and emit run-time initializers aggresively to avoid ordering issues with deferred globals. llvm-svn: 92976
* Fix linkage for RTTI names by re-using the logic for computing theDouglas Gregor2010-01-061-1/+2
| | | | | | | | linkage of vtables. Before this, we were emitting RTTI names for template instantiations with strong external linkage rather than with weak ODR linkage. llvm-svn: 92857

* Work in progress for setting the vtable pointers for all bases correctly inEli Friedman2009-12-181-2/+2
| | | | | | | the constructor. This doesn't handle cases requiring the VTT at the moment, and generates unnecessary stores, but I think it's essentially correct. llvm-svn: 91731
* Rename GetAddrOfRTTI to GetAddrOfRTTIDescriptor. Remove the overload that ↵Anders Carlsson2009-12-171-6/+3
| | | | | | takes a CXXRecordDecl since we were just creating a QualType from it anyway. llvm-svn: 91590
* Use GetAddrOfRTTI everywhere and remove GenerateRTTI and GenerateRTTIRef. ↵Anders Carlsson2009-12-161-11/+0
| | | | | | With this change, we can now compile and link TableGen. llvm-svn: 91520
* Improve linkage of RTTI data structures. Introduce ↵Anders Carlsson2009-12-111-0/+7
| | | | | | CodeGenModule::GetAddrOfRTTI which figures out the right linkage of the RTTI information for the given type and whether it should be defined or not. I will migrate clients over to GetAddrOfRTTI in subsequent commits (with tests). llvm-svn: 91098
* Work-in-progess rewrite of thunks: move thunk generation outside of vtableEli Friedman2009-12-061-0/+7
| | | | | | | generation, and make sure we generate thunks when the function is defined rather than when the vtable is defined. llvm-svn: 90722

* Simplify and fix up the handling of implicit constructors, copy assignmentEli Friedman2009-11-261-3/+0
| | | | | | | | operators, and destructors. Avoids generating declarations/definitions of trivial constructors/destructors, and makes sure the trivial copy assignment operator is generated when necessary. llvm-svn: 89943

* Fix the offset calculations for non-virtual bases with overrides.Mike Stump2009-11-121-3/+11
| | | | | | | | | Refine the VTT entries for virtual bases to refer to the complete object's vtable instead of constructor vtables. Refine the AddressPoint calculations for VTT entries for virtual bases. llvm-svn: 87021
* "Attach debug info with llvm instructions" mode was enabled a month ago. ↵Devang Patel2009-11-121-2/+0
| | | | | | Now make it permanent and remove old way of inserting intrinsics to encode debug info for locations and types. llvm-svn: 87007
* Move CompileOptions -> CodeGenOptions, and sink it into the CodeGen library.Chandler Carruth2009-11-121-4/+4

* Fix subtle bug in generating LLVM function declarations for builtin functions.Daniel Dunbar2009-09-141-1/+2
| | | | | | | | | | The decl wasn't being passed down, which meant that function attributes were not being set correctly. This is particularly important for ARM, since it wants to override the calling convention. Instead we would emit the builtin with the wrong calling convention, and instcombine would come along and merrily shred all the calls to it. :) llvm-svn: 81756
