2012-10-22Distinguish the various kinds of AST file loading failures:Douglas Gregor
file corruption, compiler version mismatch, target/language configuration mismatch, out-of-date AST file. No functionality change yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166446 91177308-0d34-0410-b5e6-96231b3b80d8
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

2012-10-21PR14141 (part of DR1351): An implicitly-deduced "any" exception specificationRichard Smith
produces an exception of 'noexcept(false)' and is thus compatible with an explicit exception specification of 'noexcept(false)'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166404 91177308-0d34-0410-b5e6-96231b3b80d8

the suggestions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166400 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

literal-operator-id. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166373 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. Patch reviewed by David Blaikie. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166281 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-19Move the set of files to be validated in an AST file into the controlDouglas Gregor
block, so the input files are validated early on, before we've committed to loading the AST file. This (accidentally) fixed a but wherein the main file used to generate the AST file would *not* be validated by the existing validation logic. At the moment, this leads to some duplication of filenames between the source manager block and input-file blocks, as well as validation logic. This will be handled via an upcoming patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166251 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-18Start factoring the on-disk records for an AST file into a controlDouglas Gregor
block, which stores information about how the AST file to generated, from the AST block, which stores the actual serialized AST. The information in the control block should be enough to determine whether the AST file is up-to-date and compatible with the current translation unit, and reading it should not cause any side effects that aren't easy to undo. That way, we can back out from an attempt to read an incompatible or out-of-date AST file. Note that there is still more factoring to do. In particular, information about the source files used to generate the AST file (along with their time stamps, sizes, etc.) still resides in the source manager block. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166166 91177308-0d34-0410-b5e6-96231b3b80d8
