come back to bite us at some point. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97607 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-01Split out types that are non-canonical unless dependent as their ownJohn McCall
category. Use this in a few places to eliminate unnecessary TST cases and do some future-proofing. Provide terrible manglings for typeof. Mangle decltype with some hope of accuracy. Our manglings for some of the cases covered in the testcase are different from gcc's, which I've raised as an issue with the ABI list. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97523 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-23When a reference to a field of a struct/union/class is passed to theCharles Davis
__alignof__ operator, make sure to take into account the packed alignment of the struct/union/class itself. Matches GCC's behavior and fixes PR6362. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96884 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-21Eliminate the default arguments to ASTContext::getFunctionType(),Douglas Gregor
fixing up a few callers that thought they were propagating NoReturn information but were in fact saying something about exception specifications. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96766 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-19Patch removes IVars list from ObjCInterfaceDecl andFariborz Jahanian

2010-02-12Patch to fix a warning which exposed a bug in buildingFariborz Jahanian
a qualified objective-c pointer type. Fixes radar 7638810. (Also removes a FIXME). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96003 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-12Fix a latent bug found by Ahmed Charles, where we were callingDouglas Gregor
ASTContext::getFunctionType with the wrong set of arguments. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95986 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-11Have ~ASTContext() delete StoredDeclsMap (internal to DeclContext) byTed Kremenek
storing the set of StoredDeclsMaps in an internal vector of void*. This isn't an ideal solution, but for the time being this fixes a major memory leak with these DenseMaps not being freed. Fixes: <rdar://problem/7634755> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95861 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-11Eliminate a bunch of unnecessary ASTContexts from members functions ofDouglas Gregor
Decl subclasses. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95841 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-11Eliminate the ASTContext parameter from RecordDecl::getDefinition()Douglas Gregor
and CXXRecordDecl::getDefinition(); it's totally unnecessary. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95836 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-10Reverse a partial fix patch for radar 7214820. It broke some code andFariborz Jahanian

ObjCObjectPointerType AST node by allocating the list of protocols after the type node itself. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95597 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-08Merge block/function pointer types with objc's __weakFariborz Jahanian
attribute properly and avoid bogus warning. This is an objective-c fix only. objective-c++ follows different code pass and requires separate fix (which will come at a later time). Fixes radar 7214820. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95571 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-05Standardize the parsing of function type attributes in a way thatJohn McCall
follows (as conservatively as possible) gcc's current behavior: attributes written on return types that don't apply there are applied to the function instead, etc. Only parse CC attributes as type attributes, not as decl attributes; don't accepet noreturn as a decl attribute on ValueDecls, either (it still needs to apply to other decls, like blocks). Consistently consume CC/noreturn information throughout codegen; enforce this by removing their default values in CodeGenTypes::getFunctionInfo(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95436 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-04Fix an obscure crash found in the Boost.MPL test suite, along with aDouglas Gregor
ton of potential crashes of the same kind. The fundamental problem is that type creation was following a dangerous pattern when using its FoldingSets: 1) Use FindNodeOrInsertPos to see if the type is available 2) If not, and we aren't looking at a canonical type, build the canonical type 3) Build and insert the new node into the FoldingSet The problem here is that building the canonical type can, in very rare circumstances, force the hash table inside the FoldingSet to reallocate. That invalidates the insertion position we computed in step 1, and in step 3 we end up inserting the new node into the wrong place. BOOM! I've audited all of ASTContext, fixing this problem everywhere I found it. The vast majority of wrong code was C++-specific (and *ahem* written by me), so I also audited other major folding sets in the C++ code (e.g., template specializations), but found no other instances of this problem. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95315 91177308-0d34-0410-b5e6-96231b3b80d8

remove some age-old FIXMEs and C++ workarounds within the type-compatibility logic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95249 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-03When determining whether a function without a prototype is compatibleDouglas Gregor
with a function with a prototype, treat parameters of enumeration type based on the enumeration type's promotion type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95238 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-27Change the return type of ASTContext::getDeclAlignInBytes() to CharUnits and,Ken Dyck
now that the "InBytes" part of the name is implied by the return type, rename it to getDeclAlign(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94681 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26Patch to add 'volatile' to first argument of allFariborz Jahanian
sync compare_and_swap to match them with gcc. It also fixes a few incorrect argument defitions. (fixes radar 7540291). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94607 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-21Allocate the 'Protocols' array in ObjCInterfaceType andTed Kremenek
ObjCObjectPointerType using the allocator associated with ASTContext. Not only does this fix a memory leak, but it also makes these arrays BumpPtrAllocated (in the typical case). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94090 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-11Roll out ASTContext::getTypeSizeInChars(), replacing instances ofKen Dyck
"ASTContext::getTypeSize() / 8". Replace [u]int64_t variables with CharUnits ones as appropriate. Also rename RawType, fromRaw(), and getRaw() in CharUnits to QuantityType, fromQuantity(), and getQuantity() for clarity. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93153 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-29Correctly refer to element CVR qualifications when determining if a type isChandler Carruth
more or less cv-qualified than another during implicit conversion and overload resolution ([basic.type.qualifier] p5). Factors the logic out of template deduction and into the ASTContext so it can be shared. This fixes several aspects of PR5542, but not all of them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92248 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-23Tidy up ~ASTContext a bit by turning orphan compound statements intoTed Kremenek
for loops. Also do not manually free the Type objects when the 'FreeMemory' flag is set, as they will be deallocated when the BumpPtrAllocator is destroyed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92047 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-09First pass at implementing C++ enum semantics: calculate (and store) anJohn McCall
"integer promotion" type associated with an enum decl, and use this type to determine which type to promote to. This type obeys C++ [conv.prom]p2 and is therefore generally signed unless the range of the enumerators forces it to be unsigned. Kills off a lot of false positives from -Wsign-compare in C++, addressing rdar://7455616 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90965 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-09Implemented an implicit conversion from "noreturn" function types (andDouglas Gregor
pointers thereof) to their corresponding non-noreturn function types. This conversion is considered an exact match for overload-resolution purposes. Note that we are a little more strict that GCC is, because we encode noreturn in the type system, but that's a Good Thing (TM) because it does not allow us to pretend that potentially-returning function pointers are non-returning function pointers. Fxies PR5620. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90913 91177308-0d34-0410-b5e6-96231b3b80d8
