2009-02-03Remove ABIArgInfo::Default kind, ABI is now responsible for specifyingDaniel Dunbar
acceptable kind with more precise semantics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63617 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-03Add ABIArgInfo::Direct kind, which passes arguments using whatever theDaniel Dunbar
native IRgen type is. This is like Default, but without any extra semantics (like automatic tweaking of structures or void). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63615 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-02Thread CGFunctionInfo construction through CodeGenTypes.Daniel Dunbar

2009-02-02ABI handling API changes.Daniel Dunbar
- Lift CGFunctionInfo creation up to callers of EmitCall. - Move isVariadic bit out of CGFunctionInfo, take as argument to GetFunctionType instead. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63550 91177308-0d34-0410-b5e6-96231b3b80d8

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: Fix thinko in prev commit, 64-bit vectors should have SSEDaniel Dunbar
class, not integer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63426 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-30x86_64 ABI: Pass <1 x double> in memory. This is arguably wrong, butDaniel Dunbar
matches gcc 4.2 (not llvm-gcc). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63413 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-30Remove testing -use-x86_64-abi option; current implementation isDaniel Dunbar
robust enough for general use. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63406 91177308-0d34-0410-b5e6-96231b3b80d8

33/500 return type failures. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63404 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

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63352 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: Tweak merging algorithm so that we always bail early whenDaniel Dunbar
we see a Memory classification. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63295 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-29ABI: When emitting calls which return an ignored argument, make sureDaniel Dunbar
to still return an RValue of the correct type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63294 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
2009-01-29x86_64: Support cases which map to returning multiple values in LLVMDaniel Dunbar
(e.g., _Complex double -> { double, double } return). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63285 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
2009-01-27Implement support for coercion to wider types during ABI handling.Daniel Dunbar

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
- 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

2008-09-26Now 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

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

2008-09-17Improve 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
