2009-01-31x86_64 ABI: Retool classification to compute lo & hi classificationsDaniel Dunbar
in terms of where the type resides in the containing object. This is a more clear embodiement of the spec & fixes a merging issue with unions. Down to 3/1000 failures. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63455 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-30x86_64 ABI: Fix more thinkos, straddling computation for complex wasDaniel Dunbar
computing in bytes not bits. We are now down to 22/1000 failures on the return types tests, and 18 of those are gcc bugs I believe. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63438 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-30x86_64 ABI: Implement classification for arrays.Daniel Dunbar
- This brings us down to an 8% failure rate on the first 500 return types tests (from 12%). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63383 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-29x86_64 ABI: Handle fields / complex components which straddleDaniel Dunbar
eightbyte boundaries. - Getting harder to test now that we handle cases gcc & llvm-gcc get wrong ( { _Complex char; _Complex int; } is a good example). :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63305 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-29x86_64 ABI: Implement classification for records.Daniel Dunbar
- This is my best initial guess at what the "spec" means, although it is not particularly clear on a number of points. Will refine through testing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63292 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-27x86_64: Classify __m64 and __m128 "correctly".Daniel Dunbar
- gcc appears to be classifying <1 x double> as INTEGER which is odd. Will investigate later. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63086 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

2008-10-13Lift out ABIInfo abstract base class.Daniel Dunbar

- return attributes - inreg, zext and sext - parameter attributes - function attributes - nounwind, readonly, readnone, noreturn Return attributes use 0 as the index.

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
