2009-01-27Implement support for coercion to wider types during ABI handling.Daniel Dunbar
- Code quality is poor, but simple. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63083 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26Add Ignore ABIArgInfo kind, for handling void & empty structures.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63039 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-24Start filling in x86_64 ABI implementation.Daniel Dunbar
- No functionality change, moved behind -use-x86_64-abi option until it becomes non-experimental. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62915 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-15Add dummy X86_64 ABIInfo implementation.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62268 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-09Provide a new kind of iterator, the specific_decl_iterator, thatDouglas Gregor
filters the decls seen by decl_iterator with two criteria: the dynamic type of the declaration and a run-time predicate described by a member function. This simplifies EnumDecl, RecordDecl, and ObjCContainerDecl considerably. It has no measurable performance impact. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61994 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-18Allow ABI to use StructRet even for scalar values.Daniel Dunbar
- Update comment to reflect fact that StructRet is now supported for any type (modulo LLVM support). - No functionality change, no scalar types currently use this feature. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61192 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-25Handle returning complex types that get coerced. Fixes PR3131Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60058 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-24Migrate some stuff from NamedDecl::getName() to Chris Lattner
NamedDecl::getNameAsString() to make it more explicit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59937 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-15Fix silly bug spotted by Daniel DunbarAnders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59358 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-15Handle complex return values.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59345 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-13Lift out ABIInfo abstract base class.Daniel Dunbar
- Currently still lives in CGCall.cpp but is intended to be the target specific place for hooking ABI information. - Select ABIInfo to use based on Target's prefix and pointer width. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57445 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-05Implement support for the const and pure attributes.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57142 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-26Now Attributes are divided in three groupsDevang Patel
- return attributes - inreg, zext and sext - parameter attributes - function attributes - nounwind, readonly, readnone, noreturn Return attributes use 0 as the index. Function attributes use ~0U as the index. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56705 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
2008-09-24Adjust whitespaces.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56538 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-24s/ParamAttrsWithIndex/FnAttributeWithIndex/gDevang Patel
Rename to match changes done on llvm side. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56537 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-17Improve x86 ABI compatibility.Daniel Dunbar
- Enables use of ABIArgInfo::Expand when needed. This greatly improves our x86 ABI compatibility. - As the infrastructure for target specific ABI handling isn't built yet, this change means ABI compatibility on other platforms is once again broken in a different way than before. - Upcoming: Figure out how to refactor ABI handling into targets. More documentation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56293 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-17Drop CodeGenTypes parameter to classifyArgumentType.Daniel Dunbar
Ensure that ABIArgInfo::Default implementation for aggregrate types is sensible (StructRet on return and ByVal on arguments). No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56289 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-17Add support for ABIArgInfo::ExpandDaniel Dunbar
- No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56269 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-11Use ABIArgInfo for decisions about function arguments (not just returnDaniel Dunbar
value). - Added ABIArgInfo::ByVal (mostly supported) and ABIArgInfo::Expand (asserted out). - Added classifyArgumentType which currently just uses ABIArgInfo::Default or ByVal. This nearly matches old behavior, but we now set ByVal in a few situations we may have left it off before (on complex, for example). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56086 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-11Bug fix, apply default argument promotion in message sends for whichDaniel Dunbar
no method declaration was found. - This was allowing arrays to pass "by value" among other things. Add assert in CodeGen that arguments cannot have array type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56080 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-10Implement ABIArgType::Coerce support.Daniel Dunbar
- As a test, enable basic usage for some common x86-32 cases. This increases our x86-32 compliance (on other targets our compliance will just be broken in a different way). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56051 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-10Add CodeGenTypes::GetFunctionType overload for getting the effectiveDaniel Dunbar
type of a call. Change NeXT runtime to use this instead of trying to bitcasting internally (which doesn't respect the ABI). Fix subtle bug, use of ConvertTypeRecursive instead of ConvertType is bad inside GetFunctionType. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56050 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
2008-09-10Add ABIArgInfo class to encapsulate ABI decision of how to lower typesDaniel Dunbar
to LLVM. - Will move to target sometime soon. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56046 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
2008-09-10Tweak CGCall functions:Daniel Dunbar
- Move actual param attr list creation to CodeGenFunction::ConstructParamAttrList. - Make ReturnTypeUsesSret static. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56038 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-09Add CodeGenFunction::ReturnTypeUsesSretDaniel Dunbar
- Hook so NeXT runtime doesn't depend on ABI. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56034 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-09Move ABI specific code for functions / calls to CGCall.cpp:Daniel Dunbar
- Factor out EmitFunction{Pro,Epi}log git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56031 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-09Change CodeGen to emit calls using (RValue,Type) list:Daniel Dunbar
- Add CodeGenFunction::EmitAnyExprToTemp o Like EmitAnyExpr, but emits aggregates to a temporary location if none is available. Seems like this should be simpler (even aside from using first class aggregates). - Killed CodeGenFunction::EmitCallArg (just append the pair) - Conversion of RValues to actual call arguments is now isolated in CodeGenFunction::EmitCall. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55970 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
