2012-04-10[code-complete] Introduce CodeCompletionTUInfo which will be used for cachingArgyrios Kyrtzidis
code-completion related strings specific to a translation unit (ASTContext and related data) CodeCompletionAllocator does such limited caching, by caching the name assigned to a DeclContext*, but that is not the appropriate place since that object has a lifetime that can extend beyond that of an ASTContext. Introduce CodeCompletionTUInfo which will be always tied to a translation unit to do this kind of caching and move the caching of CodeCompletionAllocator into this object, and propagate it to all the places where it will be needed. The plan is to extend the caching where appropriate, using CodeCompletionTUInfo, to avoid re-calculating code-completion strings.

2012-04-10Parsing of C++11 attributes:Richard Smith
* Alternative tokens (such as 'compl') are treated as identifiers in attribute names. * An attribute-list can start with a comma. * An ellipsis may not be used with either of our currently-supported C++11 attributes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154381 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

2012-04-09Fix bugs found by -Wconstant-conversion improvements currently under review.David Blaikie
Specifically, using a an integer outside [0, 1] as a boolean constant seems to be an easy mistake to make with things like "x == a || b" where the author intended "x == a || x == b". The bug caused by calling SkipUntil with three token kinds was also identified by a VC diagnostic & reported by Francois Pichet as review feedback for my commit r154163. I've included test cases to verify the error recovery that was broken/poorly implemented due to this bug. The other fix (lib/Sema/SemaExpr.cpp) seems like that code was never actually reached in any of Clang's tests & is related to Objective C features I'm not familiar with, so I've not been able to construct a test case for it. Perhaps someone else can. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154325 91177308-0d34-0410-b5e6-96231b3b80d8

case as we don't currently have any way of dumping target options or otherwise observing this. Another small step toward fixing PR12380. With this we generate TLS accesses using the static model instead of the dynamic model, but we're still generating suboptimal code under the mistaken assumption that the TLS offset might be greater than 2^32, and therefor not viable as an immediate offset of a segment register. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154298 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-08Teach Clang about PIE compilations. This is the first step of PR12380.Chandler Carruth
First, this patch cleans up the parsing of the PIC and PIE family of options in the driver. The existing logic failed to claim arguments all over the place resulting in kludges that marked the options as unused. Instead actually walk all of the arguments and claim them properly. We now treat -f{,no-}{pic,PIC,pie,PIE} as a single set, accepting the last one on the commandline. Previously there were lots of ordering bugs that could creep in due to the nature of the parsing. Let me know if folks would like weird things such as "-fPIE -fno-pic" to turn on PIE, but disable full PIC. This doesn't make any sense to me, but we could in theory support it. Options that seem to have intentional "trump" status (-static, -mkernel, etc) continue to do so and are commented as such. Next, a -pie-level flag is threaded into the frontend, rigged to a language option, and handled preprocessor, setting up the appropriate defines. We'll now have the correct defines when compiling with -fpie. The one place outside of the preprocessor that was inspecting the PIC level (as opposed to the relocation model, which is set and handled separately, yay!) is in the GNU ObjC runtime. I changed it to exactly preserve existing behavior. If folks want to change its behavior in the face of PIE, they can do that in a separate patch. Essentially the only functionality changed here is the preprocessor defines and bug-fixes to the argument management. Tests have been updated and extended to test all of this a bit more thoroughly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154291 91177308-0d34-0410-b5e6-96231b3b80d8
