2010-10-15Diagnose C++ [class.mem]p13-14, where a class member has the same nameDouglas Gregor
as the class itself. Fixes PR7082. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116573 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-14When performing typo correction, look through the set of knownDouglas Gregor
identifiers to determine good typo-correction candidates. Once we've identified those candidates, we perform name lookup on each of them and the consider the results. This optimization makes typo correction > 2x faster on a benchmark example using a single typo (NSstring) in a tiny file that includes Cocoa.h from a precompiled header, since we are deserializing far less information now during typo correction. There is a semantic change here, which is interesting. The presence of a similarly-named entity that is not visible can now affect typo correction. This is both good (you won't get weird corrections if the thing you wanted isn't in scope) and bad (you won't get good corrections if there is a similarly-named-but-completely-unrelated thing). Time will tell whether it was a good choice or not. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116528 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-14Fix compiler error that clang didn't report (probably same problem as ↵Argyrios Kyrtzidis
rdar://8552377). It's more stress-free without access checking though.. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116521 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-14Store in PCH the key function of C++ class to avoid deserializing the ↵Argyrios Kyrtzidis
complete declaration context in order to compute it. Progress for rdar://7260160. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116508 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-14Allow deserialization of just the fields of a record, when we want to ↵Argyrios Kyrtzidis
iterate over them, instead of deserializing the complete declaration context of the record. Iterating over the fields of a record is very common (e.g to determine the layout), unfortunately we needlessly deserialize every declaration that the declaration context of the record contains; this can be bad for large C++ classes that contain a lot of methods. Fix this by allow deserialization of just the fields when we want to iterate over them. Progress for rdar://7260160. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116507 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-14Introduce command line option -error-on-deserialized-decl that is ↵Argyrios Kyrtzidis
accompanied by a name and emits an error if a declaration with this name is deserialized from PCH. This is for testing, to make sure that we don't deserialize stuff needlessly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116505 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-13Introduce a bit into Type that keeps track of whether there are anyDouglas Gregor
unnamed or local types within that type. This bit is cached along with the linkage of a type, so that it can be recomputed (e.g., when we see that a typedef has given a name to an anonymous declaration). Use this bit when checking C++03 [temp.arg.type]p2, so that we don't walk template argument types repeatedly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116413 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-13Fix a silly bug in the suppression of non-error diagnostics in aDouglas Gregor
SFINAE context, where we weren't getting the right diagnostic argument count. I blame DiagnosticBuilder's weirdness. Fixes PR8372. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116411 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-13Compute whether a type is variably modified as we build the type,Douglas Gregor
rather than walking the type's structure every time we request this information. Performance optimization; no functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116409 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-13Support friend function declarations in local classes correctly.John McCall
Fixes a crash and diagnoses the error condition of an unqualified friend which doesn't resolve to something. I'm still not certain how this is useful. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116393 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-12Introduce support for emitting diagnostics (warnings + their notes)Douglas Gregor
that are suppressed during template argument deduction. This change queues diagnostics computed during template argument deduction. Then, if the resulting function template specialization or partial specialization is chosen by overload resolution or partial ordering (respectively), we will emit the queued diagnostics at that point. This addresses most of PR6784. However, the check for unnamed/local template arguments (which existed before this change) is still only skin-deep, and needs to be extended to look deeper into types. It must be improved to finish PR6784. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116373 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-12If we end up instantiating a function parameter whose default argumentDouglas Gregor
has not yet been parsed, note that the default argument hasn't been parsed and keep track of all of the instantiations of that function parameter. When its default argument does get parsed, imbue the instantiations with that default argument. Fixes PR8245. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116324 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-12When we load an ASTUnit from command-line arguments, hold on to theDouglas Gregor
diagnostics produced by the driver itself. Previously, we were allowing these to either be dropped or to slip through to stderr. Fixes <rdar://problem/7595339>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116285 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-11Eliminate -fdiagnostics-binary and all of the infrastructure forDouglas Gregor
emitting diagnostics in a binary form to be consumed by libclang, since libclang no longer does any of its work out-of-process, making this code dead. Besides, this stuff never worked at 100% anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116250 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-11Switch c-index-test from clang_codeComplete() over toDouglas Gregor
