2010-04-14Implement typo correction for Objective-C message sends when theDouglas Gregor
receiver is a mis-typed class name. Previously, we would give a non-specific typo-correction diagnostic from the expression-parsing code, but there was no fix-it because it was too late to recover. Now, we give a nice diagnostic honk.m:6:4: error: unknown receiver 'Hnk'; did you mean 'Honk'? [Hnk method]; ^~~ Honk honk.m:1:1: note: 'Honk' declared here @interface Honk ^ which includes a fix-it. We still need to recover better from mis-typing "super". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101211 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-14Introduce a parsing action to distinguish between class, instance, andDouglas Gregor
super message sends in Objective-C. No actual functionality change here, but it provides a hook so that Sema can typo-correct the receiver in some cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101207 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-13Use ASTVector instead of std::vector for the Exprs in InitListExpr. PerformanceTed Kremenek
measurements of '-fsyntax-only' on combine.c (403.gcc) shows no real performance change, but now the vector isn't leaked. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101195 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-13Introduce ASTVector, which is a std::vector-like class that allocates all memoryTed Kremenek
using the allocator associated with an ASTContext. This is largely copy-and-paste from SmallVector, and should be refactored one day. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101194 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-13IRgen: Move EmitLoadOfBitfieldLValue to use new CGBitfieldInfo::AccessInfo ↵Daniel Dunbar
decomposition, instead of computing the access policy itself. - This lets the method focus slightly more on emitting clean IR to honor the policy which has been selected. On 403.gcc's combine.c, x86_64, -O0, this reduces the number of lines in the .ll file (~= # of instructions) by 2.5%. - No intended functionality change -- at -O3 this should produce equivalent if not identical output. On 403.gcc's combine.c, x86_64, -O3, this isn't quite true and some of the changes are regressions, but I'm not going to worry about that until we move to a new access policy. - There is still some room for improvement in the generated IR, in particular we can usually fold the sign-extension of the bit-field into one of the component access. See the FIXME. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101192 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-13IRgen: Enhance CGBitFieldInfo with enough information to fully describe the ↵Daniel Dunbar
"policy" with which a bit-field should be accessed. - For now, these policies are computed to match the current IRgen strategy, although the new information isn't being used yet (except in -fdump-record-layouts). - Design comments appreciated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101178 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-13Rework the ConstStructBuilder code to emit missing initializerChris Lattner
elements with explicit zero values instead of with tail padding. On an example like this: struct foo { int a; int b; }; struct foo fooarray[] = { {1, 2}, {4}, }; We now lay this out as: @fooarray = global [2 x %struct.foo] [%struct.foo { i32 1, i32 2 }, %struct.foo { i32 4, i32 0 }] instead of as: @fooarray = global %0 <{ %struct.foo { i32 1, i32 2 }, %1 { i32 4, [4 x i8] zeroinitializer } }> Preserving both the struct type of the second element, but also the array type of the entire thing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101155 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-13Refactor and simplify the computation of implicit conversion sequencesDouglas Gregor
for reference binding. The code attempted to handle both the computation of the ICS and the actual conversion, but the latter is an anachronism: we now use InitializationSequence for that. Sema::CheckReferenceInit is now a static function TryReferenceInit that's only use within overload resolution, and has been simplified slightly. It still needs to be updated per C++ [over.ics.ref], by eliminating more of the lvalue/rvalue checks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101136 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-12Implement C++ [over.ics.user]p3, which restricts the final conversionDouglas Gregor
from a conversion function template specialization to one of exact match rank. We only know how to test this in C++0x with default function template arguments, but it's also in the C++03 spec. Fixes PR6285. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101089 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-12Improve source-location information for C++ conversion functions, byDouglas Gregor
copying the type location information from the conversion-type-id into the type location information for the function type. Do something similar for constructors and destructors, by giving their "void" return type source-location information. In all of these cases, we previously left this type-source information uninitialized, which led to various unfortunate crashes. We still aren't tracking good source-location information for the actual names. That's PR6357. John, please check my sanity on this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101088 91177308-0d34-0410-b5e6-96231b3b80d8
