2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169237 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-26Fix an edge case of mangling involving the combination of a lambda and typeid.Eli Friedman
typeid (and a couple other non-standard places where we can transform an unevaluated expression into an evaluated expression) is special because it introduces an an expression evaluation context, which conflicts with the mechanism to compute the current lambda mangling context. PR12123. I would appreciate if someone would double-check that we get the mangling correct with this patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164658 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-30Extend the "__is_pod" hack, which demotes various type trait keywordsDouglas Gregor
(__is_pod, __is_signed, etc.) to normal identifiers if they are encountered in certain places in the grammar where we know that prior versions of libstdc++ or libc++ use them, to still allow the use of these keywords as type traits. Fixes <rdar://problem/9836262> and PR10184. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162937 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-23Rip out remnants of move semantic emulation and smart pointers in Sema.Benjamin Kramer
These were nops for quite a while and only lead to confusion. ASTMultiPtr now behaves like a proper dumb array reference. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162475 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-30Improvements to vexing-parse warnings. Make the no-parameters case moreRichard Smith
accurate by asking the parser whether there was an ambiguity rather than trying to reverse-engineer it from the DeclSpec. Make the with-parameters case have better diagnostics by using semantic information to drive the warning, improving the diagnostics and adding a fixit. Patch by Nikola Smiljanic. Some minor changes by me to suppress diagnostics for declarations of the form 'T (*x)(...)', which seem to have a very high false positive rate, and to reduce indentation in 'warnAboutAmbiguousFunction'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160998 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-30Add support for the C11 _Alignof keyword.Jordan Rose
This behaves like the existing GNU __alignof and C++11 alignof keywords; most of the patch is simply adding the third token spelling to various places. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159494 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-06Whenever we have a BalancedDelimiterTracker, we have a 'nested' scopeDouglas Gregor
where '>' is going to behave as an operator (and not as a '>' closing a template argument list). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158111 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-02Revert most of r154844, which was disabled in r155975. Keep around theRichard Smith
refactorings in that revision, and some of the subsequent bugfixes, which seem to be relevant even without delayed exception specification parsing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156031 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-16Implement the last part of C++ [class.mem]p2, delaying the parsing ofDouglas Gregor
exception specifications on member functions until after the closing '}' for the containing class. This allows, for example, a member function to throw an instance of its own class. Fixes PR12564 and a fairly embarassing oversight in our C++98/03 support. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154844 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-14Add an AttributedStmt type to represent a statement with C++11 attributesRichard Smith
attached. Since we do not support any attributes which appertain to a statement (yet), testing of this is necessarily quite minimal. Patch by Alexander Kornienko! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154723 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-10Disambiguation of '[[':Richard Smith
* In C++11, '[[' is ill-formed unless it starts an attribute-specifier. Reject array sizes and array indexes which begin with a lambda-expression. Recover by parsing the lambda as a lambda. * In Objective-C++11, either '[' could be the start of a message-send. Fully disambiguate this case: it turns out that the grammars of message-sends, lambdas and attributes do not actually overlap. Accept any occurrence of '[[' where either '[' starts a message send, but reject a lambda in an array index just like in C++11 mode. Implement a couple of changes to the attribute wording which occurred after our attributes implementation landed: * In a function-declaration, the attributes go after the exception specification, not after the right paren. * A reference type can have attributes applied. * An 'identifier' in an attribute can also be a keyword. Support for alternative tokens (iso646 keywords) in attributes to follow. And some bug fixes: * Parse attributes after declarator-ids, even if they are not simple identifiers. * Do not accept attributes after a parenthesized declarator. * Accept attributes after an array size in a new-type-id. * Partially disamiguate 'delete' followed by a lambda. More work is required here for the case where the lambda-introducer is '[]'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154369 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-04For PR11916: Add support for g++'s __int128 keyword. Unlike __int128_t, this isRichard Smith
a type specifier and can be combined with unsigned. This allows libstdc++4.7 to be used with clang in c++98 mode. Several other changes are still required for libstdc++4.7 to work with clang in c++11 mode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153999 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-11Unify naming of LangOptions variable/get function across the Clang stack ↵David Blaikie

2012-03-08Streamline BalancedDelimiterTracker, by eliminating the duplicateDouglas Gregor

2012-03-06Add clang support for new Objective-C literal syntax for NSDictionary, NSArray,Ted Kremenek
NSNumber, and boolean literals. This includes both Sema and Codegen support. Included is also support for new Objective-C container subscripting. My apologies for the large patch. It was very difficult to break apart. The patch introduces changes to the driver as well to cause clang to link in additional runtime support when needed to support the new language features. Docs are forthcoming to document the implementation and behavior of these features. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152137 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-06User-defined literals: reject string and character UDLs in all places where theRichard Smith
grammar requires a string-literal and not a user-defined-string-literal. The two constructs are still represented by the same TokenKind, in order to prevent a combinatorial explosion of different kinds of token. A flag on Token tracks whether a ud-suffix is present, in order to prevent clients from needing to look at the token's spelling. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152098 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-24Implement a new type trait __is_trivially_constructible(T, Args...)Douglas Gregor
that provides the behavior of the C++11 library trait std::is_trivially_constructible<T, Args...>, which can't be implemented purely as a library. Since __is_trivially_constructible can have zero or more arguments, I needed to add Yet Another Type Trait Expression Class, this one handling arbitrary arguments.
