Daniel Dunbar fe06df4bf3 C++: Add support for -fno-use-cxa-atexit. 
- So much typing, so little gain...

Also, rename the __cxx_global_initialization function just to match llvm-gcc.

John McCall 7ec5043c2c Change CodeGenModule to rely on the Module's symbol table instead of 
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.

Douglas Gregor b14d123774 Give explicit template instantiations weak ODR linkage. Former 
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.

llvm-svn: 98441
 2010-03-13 18:23:07 +00:00
Douglas Gregor 17b76185f1 Re-revert the explicit template instantiation linkage patch. I am beginning to look incompetent

 2010-03-12 05:13:59 +00:00
Douglas Gregor ee3f72299c Give explicit template instantiations weak linkage (but don't defer 
them). Fixes PR6578.

Rafael Espindola e7113ca907 Delay codegen of vtables when handling implicit instantiations. 
This fixes PR6474.

John McCall beec5a080f Implement __builtin_dwarf_sp_column for i386 (Darwin and not), x86-64 (all), 
and ARM.  Implement __builtin_init_dwarf_reg_size_table for i386 (both) and
x86-64 (all).

Rafael Espindola 2e42fec3a0 Fix PR6473. 
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.

John McCall 731be6620c Revert changes r97693, r97700, and r97718. 
Our testing framework can't deal with disabled targets yet.

llvm-svn: 97719
 2010-03-04 04:29:44 +00:00
John McCall 6abe39c61e Create a TargetMachine whenever we create a CodeGenAction. The codegen of 
some builtins will rely on target knowledge.

John McCall f8ff7b9fd1 Perform two more constructor/destructor code-size optimizations: 
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
 2010-02-23 00:48:20 +00:00
John McCall d4324148d7 Re-introduce the ctor/dtor alias optimization, this time hidden behind a 
command-line option which defaults off.

llvm-svn: 96649
 2010-02-19 01:32:20 +00:00
John McCall 334ce7c1c4 Revert the ctor/dtor alias optimization for now; the buildbots can detect 
some failure here that I can't.

llvm-svn: 96612
 2010-02-18 21:31:48 +00:00
John McCall 67cea74745 Emit complete constructors and destructors as aliases to base constructors 
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.

Anders Carlsson 6710c5351e Use the correct function info for constructors when applying function attributes. Fixes PR6245.

Ken Dyck 98ca79435a Introduce CodeGenModule::GetTargetTypeStoreSize() to calculate the store size 
of LLVM types in character units.

David Chisnall 481e3a87fe Created __builtin___NSStringMakeConstantString() builtin, which generates constant Objective-C strings.

Anton Korobeynikov 55bcea1e65 Generalize target weirdness handling having proper layering in mind: 
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.

Eli Friedman 5866fe306d Fix for PR5967: Make const-marking for LLVM globals correct for cases requiring 
run-time initialization, and emit run-time initializers aggresively to avoid
ordering issues with deferred globals.

llvm-svn: 92976
 2010-01-08 00:50:11 +00:00
Douglas Gregor 2a34df3264 Fix linkage for RTTI names by re-using the logic for computing the 
linkage of vtables. Before this, we were emitting RTTI names for
template instantiations with strong external linkage rather than with
weak ODR linkage.

 2010-01-02 18:02:32 +00:00
Eli Friedman 70724ad2ff Work in progress for setting the vtable pointers for all bases correctly in 
the constructor.  This doesn't handle cases requiring the VTT at the moment,
and generates unnecessary stores, but I think it's essentially correct.

 2009-12-18 23:47:41 +00:00
Anders Carlsson 3f4336cb1f Rename GetAddrOfRTTI to GetAddrOfRTTIDescriptor. Remove the overload that takes a CXXRecordDecl since we were just creating a QualType from it anyway. 
llvm-svn: 91590
 2009-12-17 07:09:17 +00:00
Anders Carlsson 07863b8b6e Use GetAddrOfRTTI everywhere and remove GenerateRTTI and GenerateRTTIRef. With this change, we can now compile and link TableGen. 
llvm-svn: 91520
 2009-12-16 07:05:41 +00:00
Anders Carlsson fd7dfeb779 Improve linkage of RTTI data structures. Introduce 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
 2009-12-11 02:46:30 +00:00
Eli Friedman 8174f2c23c Work-in-progess rewrite of thunks: move thunk generation outside of vtable 
generation, and make sure we generate thunks when the function is defined
rather than when the vtable is defined.

llvm-svn: 90722
 2009-12-06 22:01:30 +00:00
Anders Carlsson fe5f7d916f Set the correct linkage for VTTs as well.
