2010-10-22Substantially revise how clang computes the visibility of a declaration toJohn McCall
more closely parallel the computation of linkage. This gets us to a state much closer to what gcc emits, modulo bugs, which will undoubtedly arise in abundance. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117147 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-21Tweak diagnostics for redeclaration of a @property in a class extension ↵Ted Kremenek
where the redelcaration and original declaration have the 'readwrite' attribute. This is a common case, and we can issue a more lucid diagnostic. Fixes <rdar://problem/7629420>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117045 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-21Diagnose the declaration of template template parameters thatDouglas Gregor
themselves have no template parameters. This is actually a restriction due to the grammar of template template parameters, but we choose to diagnose it in Sema to provide better recovery. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117032 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-21Always treat 'main' as an extern "C" function, so that we detectDouglas Gregor
redeclarations of main appropriately rather than allowing it to be overloaded. Also, disallowing declaring main as a template. Fixes GCC DejaGNU g++.old-deja/g++.other/main1.C. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117029 91177308-0d34-0410-b5e6-96231b3b80d8

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

2010-10-13Generalize the checking for qualification of (non-friend) classDouglas Gregor
members. Provide a hard error when the qualification doesn't match the current class type, or a warning + Fix-it if it does match the current class type. Fixes PR8159. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116445 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
2010-10-13Support 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

2010-10-12Add some infrastructure for dealing with expressions of 'placeholder' type,John McCall
i.e. expressions with an internally-convenient type which should not be appearing in generally valid, complete ASTs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116281 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-11Driver/Darwin: Remove a useless warning about missing runtime libraries. TheseDaniel Dunbar
are almost never needed, so the warning isn't very useful. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116263 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
