2011-06-27Improve header search for MinGW(-w64), from Ruben Van Boxem!Douglas Gregor

2011-06-27Fix missing braces around two statements that were intended to be partChandler Carruth
of a single if block. This is really annoying to track down and test. Silly changes to the test case caused it to stop showing up. I wish there were a more concrete way of asserting that a note attaches to the intended diagnostic. This fixes PR10195. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133907 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-27Factor out (some of) the checking for invalid forms of pointerChandler Carruth
arithmetic into a couple of common routines. Use these to make the messages more consistent in the various contexts, especially in terms of consistently diagnosing binary operators with invalid types on both the left- and right-hand side. Also, improve the grammar and wording of the messages some, handling both two pointers and two (different) types. The wording of function pointer arithmetic diagnostics still strikes me as poorly phrased, and I worry this makes them slightly more awkward if more consistent. I'm hoping to fix that with a follow-on patch and test case that will also make them more helpful when a typedef or template type parameter makes the type completely opaque. Suggestions on better wording are very welcome, thanks to Richard Smith for some initial help on that front. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133906 91177308-0d34-0410-b5e6-96231b3b80d8

When performing semantic analysis on a member declaration, fix the check for whether we are declaring a function to check for parenthesized declarators, declaration via decltype, etc. Also fix the semantic check to not treat FuncType* as a function type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133862 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-25When deciding how to parse "= something" as part of a memberDouglas Gregor

2011-06-24This patch started as an attempt to fix up the horrid namingSean Hunt
conventions. I then discovered a typo in the using declaration bit in LookupSpecialMember. This led to discovering [namespace.udecl]p15, which clang implements incorrectly. Thus I've added a comment and implemented the code consistently with the rest of clang - that is incorrectly. And because I don't want to include tests of something incorrect, I've ripped the test out. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133784 91177308-0d34-0410-b5e6-96231b3b80d8
