2010-03-22We want to add all thunks, not just 'this' adjustment thunks.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99177 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-22Introduce the notion of a single "delayed" diagnostic into theDouglas Gregor
Diagnostic subsystem, which is used in the rare case where we find a serious problem (i.e., an inconsistency in the file system) while we're busy formatting another diagnostic. In this case, the delayed diagnostic will be emitted after we're done with the other diagnostic. This is only to be used for fatal conditions detected at very inconvenient times, where we can neither stop the current diagnostic in flight nor can we suppress the second error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99175 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-22When handling a TSK_ExplicitInstantiationDefinition after aRafael Espindola
TSK_ExplicitInstantiationDeclaration make sure we call MaybeMarkVirtualMembersReferenced with a method attached to the definition. Remove the hack that forced vtable emition with declarations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99174 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-22-Wshadow should only warn about parameter declarations when we'reJohn McCall
entering a function or block definition, not on every single declaration. Unfortunately we don't have previous-lookup results around when it's time to make this decision, so we have to redo the lookup. The alternative is to use delayed diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99172 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-22Add very limited support for GCC's '-B' flag. This allows us to support unusualChandler Carruth
toolchain configurations and is a small step toward FreeBSD support. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99159 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-21Fix PR6618.Rafael Espindola
If a struct has an invalid field, mark it as invalid. Also avoid producing errors about incomplete types that are invalid. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99150 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-21Keep track of the size/modification time of each file source-locationDouglas Gregor
entry in a precompiled header, so that we can detect modified files even when we miss in the stat cache. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99149 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99140 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-21Fix PR6648 by not creating a temporary with the type of aRafael Espindola
CXXExprWithTemporaries. Not emitting the expression as an aggregate might be the right thing to do, but is orthogonal. Emitting it as an scalar expression will still try to create a temporary for the incomplete type of the CXXExprWithTemporaries and fail. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99134 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99114 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-20Don't bother running the analysis for CFG-based warnings if theTed Kremenek
declaration is in a system header. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99087 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-20Refactor CFG-based warnings in Sema to be run by a worked object called ↵Ted Kremenek
AnalysisBasedWarnings. This object controls when the warnings are executed, allowing the client code in Sema to selectively disable warnings as needed. Centralizing the logic for analysis-based warnings allows us to optimize when and how they are run. Along the way, remove the redundant logic for the 'check fall-through' warning for blocks; now the same logic is used for both blocks and functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99085 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-20IRgen: Wrap atomic intrinsics with memory barriers, to ensure we honor the ↵Daniel Dunbar
semantics. - This should be conservatively correct, we eventually should have target hooks for platforms that are less strict. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99050 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-20Evaluate: Fix a subtle bug in the pointer evaluator in which we would do anDaniel Dunbar
expression computation in the wrong bit-width, and end up generating a totally bogus array reference (_g0+8589934546). - This showed up on Prolangs/cdecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99042 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-19Change CodeGenModule to rely on the Module's symbol table instead ofJohn McCall
shadowing it in the GlobalDeclMap. Eliminates the string-uniquing requirement for mangled names, which should help C++ codegen times a little. Forces us to do string lookups instead of pointer lookups, which might hurt codegen times a little across the board. We'll see how it plays out. Removing the string-uniquing requirement implicitly fixes any bugs like PR6635 which arose from the fact that we had multiple uniquing tables for different kinds of identifiers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99012 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19Remove the capture, serialization, and deserialization of commentDouglas Gregor
ranges as part of the ASTContext. This code is not and was never used, but contributes ~250k to the size of the Cocoa.h precompiled header. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99007 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19Robustify PreprocessingRecord slightly, by only creating macroDouglas Gregor
instantiations when we have the corresponding macro definition and by removing macro definition information from our table when the macro is undefined. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99004 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19Implement serialization and lazy deserialization of the preprocessingDouglas Gregor
record (which includes all macro instantiations and definitions). As with all lay deserialization, this introduces a new external source (here, an external preprocessing record source) that loads all of the preprocessed entities prior to iterating over the entities. The preprocessing record is an optional part of the precompiled header that is disabled by default (enabled with -detailed-preprocessing-record). When the preprocessor given to the PCH writer has a preprocessing record, that record is written into the PCH file. When the PCH reader is given a PCH file that contains a preprocessing record, it will be lazily loaded (which, effectively, implicitly adds -detailed-preprocessing-record). This is the first case where we have sections of the precompiled header that are added/removed based on a compilation flag, which is unfortunate. However, this data consumes ~550k in the PCH file for Cocoa.h (out of ~9.9MB), and there is a non-trivial cost to gathering this detailed preprocessing information, so it's too expensive to turn on by default. In the future, we should investigate a better encoding of this information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99002 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-19clang -cc1: Kill off -empty-input only, and replace with -init-only which is anDaniel Dunbar
actual action. - This is easier to use, and more reliable for timing the thing this was actually meant to be useful for. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98978 91177308-0d34-0410-b5e6-96231b3b80d8

object pointer types. Fixes radar 7634850. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98970 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19Make the preprocessing record a PPCallbacks subclass itself,Douglas Gregor
eliminating the extra PopulatePreprocessingRecord object. This will become useful once we start writing the preprocessing record to precompiled headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98966 91177308-0d34-0410-b5e6-96231b3b80d8

information, to address recent gdb failures. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98959 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19Pretty-print anonymous types using their kind and presumed location.John McCall
Fixes PR6643. Patch by Mike M! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98946 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19Remember the "found declaration" for an overload candidate, which is theJohn McCall
entity (if applicable) which was actually looked up. If a candidate was found via a using declaration, this is the UsingShadowDecl; otherwise, if the candidate is template specialization, this is the template; otherwise, this is the function. The point of this exercise is that "found declarations" are the entities we do access control for, not their underlying declarations. Broadly speaking, this patch fixes access control for using declarations. There is a *lot* of redundant code calling into the overload-resolution APIs; we really ought to clean that up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98945 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19Fix a longstanding (but previously unknown) bug in the lazyDouglas Gregor
deserialization of precompiled headers, where the deserialization of the source location entry for a buffer (e.g., macro instantiation scratch space) would overwrite a one-element FileID cache in the source manager. When tickled at the wrong time, we would return the wrong decomposed source location and eventually cause c-index-test to crash. Found by dumb luck. It's amazing this hasn't shown up before. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98940 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-18When elevating access along an inheritance path, initialize the computedJohn McCall
access to the (elevated) access of the accessed declaration, if applicable, rather than plunking that access onto the end after we've calculated the inheritance access. Also, being a friend of a derived class gives you public access to its members (subject to later modification by further inheritance); it does not simply ignore a single location of restricted inheritance. Also, when computing the best unprivileged path to a subobject, preserve the information that the worst path might be AS_none (forbidden) rather than a minimum of AS_private. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98899 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-18For debug information, get the main file name from the source managerDouglas Gregor
rather than from the -main-file-name flag, since the source manager has proper path information. Fixes <rdar://problem/7769538>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98898 91177308-0d34-0410-b5e6-96231b3b80d8
