* Avoid recursions when the parser finds out that it has too many brackets.Rafael Espindola2013-07-251-1/+11
| | | | | | | | | BalancedDelimiterTracker::diagnoseOverflow calls P.SkipUntil, and before this patch P.SkipUnti is recursive, causing problems on systems with small stacks. This patch fixes it by making P.SkipUnti non recursive when just looking for eof. llvm-svn: 187097
* "bool" should be a context-sensitive keyword in Altivec mode.Bill Schmidt2013-07-031-0/+1
| | | | | | | | | | | | | | | | | PR16456 reported that Clang implements a hybrid between AltiVec's "Keyword and Predefine Method" and its "Context Sensitive Keyword Method," where "bool" is always a keyword, but "vector" and "pixel" are context-sensitive keywords. This isn't permitted by the AltiVec spec. For consistency with gcc, this patch implements the Context Sensitive Keyword Method for bool, and stops treating true and false as keywords in Altivec mode. The patch removes KEYALTIVEC as a trigger for defining these keywords in include/clang/Basic/TokenKinds.def, and adds logic for "vector bool" that mirrors the existing logic for "vector pixel." The test case is taken from the bug report. llvm-svn: 185580

* Forward #pragma comment(lib/linker) through as flags metadataReid Kleckner2013-05-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | Summary: Most of this change is wiring the pragma all the way through from the lexer, parser, and sema to codegen. I considered adding a Decl AST node for this, but it seemed too heavyweight. Mach-O already uses a metadata flag called "Linker Options" to do this kind of auto-linking. This change follows that pattern. LLVM knows how to forward the "Linker Options" metadata into the COFF .drectve section where these flags belong. ELF support is not implemented, but possible. This is related to auto-linking, which is http://llvm.org/PR13016. CC: cfe-commits Differential Revision: http://llvm-reviews.chandlerc.com/D723 llvm-svn: 181426

* [Sema] Semantic analysis for empty-declaration and attribute-declaration.Michael Han2013-02-221-8/+4
| | | | | | | | Introduce a new AST Decl node "EmptyDecl" to model empty-declaration. Have attributes from attribute-declaration appertain to the EmptyDecl node by creating the AST representations of these attributes and attach them to the EmptyDecl node so these attributes can be sema checked just as attributes attached to "normal" declarations. llvm-svn: 175900
* Add -fbracket-depth=N, analogous to -ftemplate-depth= and -fconstexpr-depth=,Richard Smith2013-02-221-1/+3
| | | | | | | | | | | to control the check for the C 5.2.4.1 / C++ [implimits] restriction on nesting levels for parentheses, brackets and braces. Some code with heavy macro use exceeds the default limit of 256, but we don't want to increase it generally to avoid stack overflow on stack-constrained systems. llvm-svn: 175855

* Finish semantic analysis for [[carries_dependency]] attribute.Richard Smith2013-01-281-1/+2
| | | | | | | | | | This required plumbing through a new flag to determine whether a ParmVarDecl is actually a parameter of a function declaration (as opposed to a function typedef etc, where the attribute is prohibited). Weirdly, this attribute (just like [[noreturn]]) cannot be applied to a function type, just to a function declaration (and its parameters). llvm-svn: 173726
* Implement C++11 semantics for [[noreturn]] attribute. This required splittingRichard Smith2013-01-171-1/+2
| | | | | | | | it apart from [[gnu::noreturn]] / __attribute__((noreturn)), since their semantics are not equivalent (for instance, we treat [[gnu::noreturn]] as affecting the function type, whereas [[noreturn]] does not). llvm-svn: 172691

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. llvm-svn: 169237

| | | | | | | | | | | | | | | | | nested names as id-expressions, using the annot_primary_expr annotation, where possible. This removes some redundant lookups, and also allows us to typo-correct within tentative parsing, and to carry on disambiguating past an identifier which we can determine will fail lookup as both a type and as a non-type, allowing us to disambiguate more declarations (and thus offer improved error recovery for such cases). This also introduces to the parser the notion of a tentatively-declared name, which is an identifier which we *might* have seen a declaration for in a tentative parse (but only if we end up disambiguating the tokens as a declaration). This is necessary to correctly disambiguate cases where a variable is used within its own initializer. llvm-svn: 162159

* Better parser recovery in Objective-C containers.Jordan Rose2012-07-091-1/+1
| | | | | | | | | | | | | | Previously it was possible to get an infinite-loop-on-invalid with a namespace decl within @interface. Since 'namespace' is normally a safe place to retry top-level parsing, we just didn't consume the token. This adds a flag that tracks whether we have temporarily left Objective-C scope to parse a C-like declaration, and uses that to better recover from parse problems by stopping at possible method declarations and at @end. To fix the original problem, we do /not/ stop at 'namespace' when in an Objective-C @interface or @protocol context (but still do in @implementation). llvm-svn: 159941
