2009-03-06(LLVM svn up) Generalize RuntimeFunctions to RuntimeGlobals and addDaniel Dunbar
CodeGenModule::CreateRuntimeVariable. - No real functionality change; although we now assert on silly things like: -- int objc_exception_throw; void f0() { @throw(@"A"); } -- instead of accepting it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66292 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04Move more of the blocks code up and out.Mike Stump
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66046 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04Move more of blocks codegen out of CodeGenModule and into theMike Stump
BlockModule. No functionality change. This should help people that don't want to know anything about blocks not be confused by the overloaded use of the term block or nor want to see all the blocks goop. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66042 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04Start the migration of more of the blocks code out of sight for mostMike Stump
people. De-duplicates BLOCK_NEEDS_FREE and friends. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66034 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04Improved ABI compliance for __block variables. No testcases yet as weMike Stump
still give an unsupported error for them due to the fact this is a work in progress. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66007 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-27Fix PR3612. We ensure that we add builtins to the GlobalDeclMap andMike Stump
we ensure that things added to the module can be found even when they are not in GlobalDeclMap. The later is for increased flexibility, should someone want to do something tricky like extern "Ada" in the same module. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65657 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24first wave of fixes for @encode sema support. This is part of PR3648.Chris Lattner
The big difference here is that (like string literal) @encode has array type, not pointer type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65391 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-19More codegen for blocks. The type of block literals should be better.Mike Stump
The size calculation is improved. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64994 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64984 91177308-0d34-0410-b5e6-96231b3b80d8
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
2009-02-12Add a very basic implemenation of global blocks. This needs to be cleaned up.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64387 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-02More ABI API cleanup.Daniel Dunbar
- Lift CGFunctionInfo creation above ReturnTypeUsesSret and EmitFunction{Epi,Pro}log. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63553 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-31Kill off CGCallInfo, always use CGFunctionInfo for encapsulatingDaniel Dunbar
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

2008-08-26Objective-C @synthesize support.Daniel Dunbar
- Only supports simple assignment and atomic semantics are ignored. - Not quite usable yet because the methods do not actually get added to the class metadata. - Added ObjCPropertyDecl::getSetterKind (one of Assign, Copy, Retain). - Rearrange CodeGenFunction so synthesis can reuse function prolog / epilog code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55365 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55303 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23NeXT: Clean up constant CFString handling.Daniel Dunbar
- Use CodeGenModule::GetAddrOfConstantCFString Some tweaks of CodeGenModule::GetAddrOfConstantCFString git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55243 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-16Change WarnUnsupported to ErrorUnsupported (in name and in practice).Daniel Dunbar
- We are beyond the point where this shows up often and when it does generating miscompiled files is bad. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54836 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-15Clean up CodeGenModule interface.Daniel Dunbar
- Add CodeGenModule::EmitTopLevelDecl which uses switch on kind instead of ugly & slow dyn_cast chains. - Drop some simple forwarding methods into the ObjC runtime. - Privatize appropriate methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54827 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-13Add GetAddrOfConstantCString methodDaniel Dunbar
- Returns addr of constant for argument + '\0'. - I couldn't think of a better name. - Move appropriate users of GetAddrOfConstantString to this. Rename getStringForStringLiteral to GetStringForStringLiteral. Add GetAddrOfConstantStringFromLiteral - This combines GetAddrOfConstantString and GetStringForStringLiteral. This method can be, but is not yet, more efficient. Change GetAddrOfConstantString to not add terminating '\0' - <rdar://problem/6140956> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54768 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-13Change ObjCRuntime GenerateProtocol[Ref] methods to takeDaniel Dunbar
ObjCProtocolDecl directly. Implement CodeGen support for forward protocol decls (no-ops are so nice to implement). Also moved CGObjCRuntime.h out of CodeGenModule.h git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54709 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-11Add LangOptions::NeXTRuntime.Daniel Dunbar
- Wired to -fnext-runtime and -fgnu-runtime options. - Defaults to GNU, no autoselection for NeXT. Emit NeXT OBJC_IMAGE_INFO marker. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54651 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-11Change CodeGenModule to only create ObjC runtime for ObjC filesDaniel Dunbar
- Changed CodeGenModule::getObjCRuntime to return reference. - Added CodeGenModule::hasObjCRuntime predicate. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54645 91177308-0d34-0410-b5e6-96231b3b80d8
