we ensure that things added to the module can be found even when they are not in GlobalDeclMap.

2009-02-17Change EmitConstantExpr to allow failure.Daniel Dunbar
IRgen no longer relies on isConstantInitializer, instead we just try to emit the constant. If that fails then in C we emit an error unsupported (this occurs when Sema accepted something that it doesn't know how to fold, and IRgen doesn't know how to emit) and in C++ we emit a guarded initializer. This ends up handling a few more cases, because IRgen was actually able to emit some of the constants Sema accepts but can't Evaluate(). For example, PR3398. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64780 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-13Add basic support for C++ name mangling according to the Itanium C++Douglas Gregor
ABI to the CodeGen library. Since C++ code-generation is so incomplete, we can't exercise much of this mangling code. However, a few smoke tests show that it's doing the same thing as GCC. When C++ codegen matures, we'll extend the ABI tester to verify name-mangling as well, and complete the implementation here. At this point, the major client of name mangling is in the uses of the new "overloadable" attribute in C, which allows overloading. Any "overloadable" function in C (or in an extern "C" block in C++) will be mangled the same way that the corresponding C++ function would be mangled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64413 91177308-0d34-0410-b5e6-96231b3b80d8

function/call info. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63466 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-04Fix the bug that would cause Python to crash at startup.Anders Carlsson
When emitting the static variables we need to make sure that the order is preserved. Fix this by making StaticDecls a std::list which has O(1) random removal. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61621 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-17Add option argument to GetAddrOfConstantString to use for name ofDaniel Dunbar
(first) global holding the string. - No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57736 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-01Add simple interface for protecting runtime functions from nameDaniel Dunbar
collisions. - Provide CodeGenModule::CreateRuntimeFunction which guarantees that the function it creates will have the provided name in the final module. This allows the runtime to have its functions protected from declarations of the same name in the source code. - One could argue that this is a reason to abuse the llvm::Module namespace for dealing with function redeclarations. However, that approach seems conceptually flawed to me. This one also happens to be somewhat more efficient. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56899 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-25 Large mechanical patch.Devang Patel
s/ParamAttr/Attribute/g s/PAList/AttrList/g s/FnAttributeWithIndex/AttributeWithIndex/g s/FnAttr/Attribute/g This sets the stage - to implement function notes as function attributes and - to distinguish between function attributes and return value attributes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56623 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-10Move FunctionType conversion into CGCall.cpp:Daniel Dunbar
- Added CodeGenTypes::GetFunctionType, taking a CGFunctionInfo. - Updated Obj-C runtimes to use this instead of rolling the llvm::FunctionType by hand. - Killed CodeGenTypes::{ConvertReturnType, DecodeArgumentTypes}. Add ABIArgInfo class to encapsulate ABI decision of how to lower types to LLVM. - Will move to target sometime soon. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56047 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-10Tweak CGCall functions again:Daniel Dunbar
- Realized these functions will eventually need access to more data, moved to CodeGenModule. Eventually they should probably live together in some other helper class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56039 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-08Fix a number of issues w.r.t. emission of global for functions andDaniel Dunbar
aliases. - Attributes specific to a definition are only set when the definition is seen. - Alias generation is delayed until the end of the module; necessary since the alias may reference forward. - Fixes: PR2743, <rdr://6140807&6094512> - Improves: <rdr://6095112> (added XFAIL) Also, print module on verification failures. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55966 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-08Refactor parameter attribute handling:Daniel Dunbar
- Add CGCall.h for dealing with ABI issues related to calls. - Add CGFunctionInfo and CGCallInfo for capturing ABI relevant information about functions and calls. - Isolate LLVM parameter attribute handling inside CGCall.cpp git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55963 91177308-0d34-0410-b5e6-96231b3b80d8
