2012-10-24Teach the PCH validator to check the preprocessor options, especiallyDouglas Gregor
the macros that are #define'd or #undef'd on the command line. This checking happens much earlier than the current macro-definition checking and is far cleaner, because it does a direct comparison rather than a diff of the predefines buffers. Moreover, it allows us to use the result of this check to skip over PCH files within a directory that have non-matching -D's or -U's on the command line. Finally, it improves the diagnostics a bit for mismatches, fixing <rdar://problem/8612222>. The old predefines-buffer diff'ing will go away in a subsequent commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166641 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-23[analyzer] Replace -analyzer-no-eagerly-trim-egraph with graph-trim-interval.Jordan Rose
After every 1000 CFGElements processed, the ExplodedGraph trims out nodes that satisfy a number of criteria for being "boring" (single predecessor, single successor, and more). Rather than controlling this with a cc1 option, which can only disable this behavior, we now have an analyzer-config option, 'graph-trim-interval', which can change this interval from 1000 to something else. Setting the value to 0 disables reclamation. The next commit relies on this behavior to actually test anything. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166528 91177308-0d34-0410-b5e6-96231b3b80d8

check each of the files within that directory to determine if any of them is an AST file that matches the language and target options. If so, the first matching AST file is loaded.

2012-10-22[Options] Add prefixes to options.Michael J. Spencer
Each option has a set of prefixes. When matching an argument such as -funroll-loops. First the leading - is removed as it is a prefix. Then a lower_bound search for "funroll-loops" is done against the option table by option name. From there each option prefix + option name combination is tested against the argument. This allows us to support Microsoft style options where both / and - are valid prefixes. It also simplifies the cases we already have where options come in both - and -- forms. Almost every option for gnu-ld happens to have this form. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166444 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-22Eliminate the redundancy between source-file information in the sourceDouglas Gregor
manager block and input-file information in the control block. The source manager entries now point back into the control block. Input files are now lazily deserialized (if validation is disabled). Reduces Cocoa's PCH by the ~70k I added when I introduced the redundancy in r166251. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166429 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-21Unrevert r166268, reverted in r166272, with a fix for the issue which NickRichard Smith
found: if an overloaded operator& is present before a template definition, the expression &T::foo is represented as a CXXOperatorCallExpr, not as a UnaryOperator, so we didn't notice that it's permitted to reference a non-static data member of an unrelated class. While investigating this, I discovered another problem in this area: we are treating template default arguments as unevaluated contexts during substitution, resulting in performing incorrect checks for uses of non-static data members in C++11. That is not fixed by this patch (I'll look into this soon; it's related to the failure to correctly instantiate constexpr function templates), but was resulting in this bug not firing in C++11 mode (except with -Wc++98-compat). Original message: PR14124: When performing template instantiation of a qualified-id outside of a class, diagnose if the qualified-id instantiates to a non-static class member. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166385 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-20Rework implementation of DR1492: Apply the resolution to operator delete too,Richard Smith
since it also has an implicit exception specification. Downgrade the error to an extwarn, since at least for operator delete, system headers like to declare it as 'noexcept' whereas the implicit definition does not have an explicit exception specification. Move the exception specification for user-declared 'operator delete' functions from the type-as-written into the type, to reflect reality and to allow us to detect whether there was an implicit exception spec or not. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166372 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-20Accept -Wno-arc-abi without warning for a while.Nico Weber
Xcode 4.5 passes -Wno-arc-abi to clang, which makes a clang newer than r163917 warn that it doesn't understand -Wno-arc-abi. I asked if adding this is ok at http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20121015/066433.html and nobody objected. Adding this makes life a bit easier for the chromium project. If you think this is a burden on for clang, shout, and I'll revert this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166370 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-19Allow objc_requires_super to be used to check class methods as well.Jordan Rose
Also, unify ObjCShouldCallSuperDealloc and ObjCShouldCallSuperFinalize. The two have identical behavior and will never be active at the same time. There's one last simplification now, which is that if we see a call to [super foo] and we are currently in a method named 'foo', we will /unconditionally/ clear the ObjCShouldCallSuper flag, rather than check first to see if we're in a method where calling super is required. There's no reason to pay the extra lookup price here. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166285 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-19Change VerifyDiagnosticConsumer so that it *must* contain at least one ↵Andy Gibbs
"expected-*" directive. As a result, for test-cases that are not expected to generate any diagnostics, an additional directive "expected-no-diagnostics" has been implemented which can then be included in such test-cases. This new directive may not be used in conjunction with any other "expected-*" directive. This change was initially proposed as a solution to the problem highlighted by check-in r164677, i.e. that -verify will not cause a test-case failure where the compile command does not actually reference the file.
