2010-03-23More thunks scaffolding.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99294 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-23Rename CGVtableInfo to CodeGenVTables in preparation of adding another ↵Anders Carlsson
VTableInfo class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99250 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-20C++: Add support for -fno-use-cxa-atexit.Daniel Dunbar
- So much typing, so little gain... Also, rename the __cxx_global_initialization function just to match llvm-gcc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99039 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19Change CodeGenModule to rely on the Module's symbol table instead ofJohn McCall
shadowing it in the GlobalDeclMap. Eliminates the string-uniquing requirement for mangled names, which should help C++ codegen times a little. Forces us to do string lookups instead of pointer lookups, which might hurt codegen times a little across the board. We'll see how it plays out. Removing the string-uniquing requirement implicitly fixes any bugs like PR6635 which arose from the fact that we had multiple uniquing tables for different kinds of identifiers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99012 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-13Give explicit template instantiations weak ODR linkage. FormerDouglas Gregor
iterations of this patch gave explicit template instantiation link-once ODR linkage, which permitted the back end to eliminate unused symbols. Weak ODR linkage still requires the symbols to be generated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98441 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-13Re-revert the explicit template instantiation linkage patch. I am beginning ↵Douglas Gregor

2010-03-13Reinstate patch to turn explicit template instantiations into weak symbolsDouglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98424 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-12Revert the linkage change for explicit template instantiations; something is ↵Douglas Gregor
amiss git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98332 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-12Give explicit template instantiations weak linkage (but don't deferDouglas Gregor
them). Fixes PR6578. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98328 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-10Delay codegen of vtables when handling implicit instantiations.Rafael Espindola
This fixes PR6474. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98123 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-06Implement __builtin_dwarf_sp_column for i386 (Darwin and not), x86-64 (all),John McCall
and ARM. Implement __builtin_init_dwarf_reg_size_table for i386 (both) and x86-64 (all). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97859 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-04Fix PR6473.Rafael Espindola
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97733 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-04Revert changes r97693, r97700, and r97718.John McCall
Our testing framework can't deal with disabled targets yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97719 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-04Create a TargetMachine whenever we create a CodeGenAction. The codegen ofJohn McCall
some builtins will rely on target knowledge. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97693 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-23Perform two more constructor/destructor code-size optimizations:John McCall
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96842 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-19Re-introduce the ctor/dtor alias optimization, this time hidden behind aJohn McCall
command-line option which defaults off. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96649 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-18Revert the ctor/dtor alias optimization for now; the buildbots can detectJohn McCall
some failure here that I can't. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96612 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-17Emit complete constructors and destructors as aliases to base constructorsJohn McCall
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96451 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-06Use the correct function info for constructors when applying function ↵Anders Carlsson

2010-02-02Move pointer to data member emission to CodeGenModule and use it in ↵Anders Carlsson
CGExprConstant. Fixes PR5674. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95063 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-31Some class related cleanup.Anders Carlsson

2010-01-10Generalize target weirdness handling having proper layering in mind:Anton Korobeynikov
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93118 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-08Fix for PR5967: Make const-marking for LLVM globals correct for cases requiringEli Friedman
run-time initialization, and emit run-time initializers aggresively to avoid ordering issues with deferred globals. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92976 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-06Fix linkage for RTTI names by re-using the logic for computing theDouglas Gregor
linkage of vtables. Before this, we were emitting RTTI names for template instantiations with strong external linkage rather than with weak ODR linkage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92857 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-18Work in progress for setting the vtable pointers for all bases correctly inEli Friedman
the constructor. This doesn't handle cases requiring the VTT at the moment, and generates unnecessary stores, but I think it's essentially correct. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91731 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-17Rename GetAddrOfRTTI to GetAddrOfRTTIDescriptor. Remove the overload that ↵Anders Carlsson
takes a CXXRecordDecl since we were just creating a QualType from it anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91590 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-16Use GetAddrOfRTTI everywhere and remove GenerateRTTI and GenerateRTTIRef. ↵Anders Carlsson
With this change, we can now compile and link TableGen. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91520 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-11Improve linkage of RTTI data structures. Introduce ↵Anders Carlsson
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). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91098 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-06Work-in-progess rewrite of thunks: move thunk generation outside of vtableEli Friedman
generation, and make sure we generate thunks when the function is defined rather than when the vtable is defined. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90722 91177308-0d34-0410-b5e6-96231b3b80d8
