* Make sure we apply attributes to correct places.Bill Wendling2013-02-221-13/+17
| | | | | | | Some attributes make sense only on the function or on the call site, but not both. Make this distinction here. llvm-svn: 175918
* Split out the command handling for split debug info, we're goingEric Christopher2013-02-224-32/+46
| | | | | | | | | to want to propagate some information through the module into the back end and so need to pass it through to codegen. Also make the methods file static so we can use them in other places. llvm-svn: 175916
* [analyzer] Don't canonicalize the RecordDecl used in CXXBaseObjectRegion.Jordan Rose2013-02-222-2/+32
| | | | | | | | | | | This Decl shouldn't be the canonical Decl; it should be the Decl used by the CXXBaseSpecifier in the subclass. Unfortunately, that means continuing to throw getCanonicalDecl() on all comparisons. This fixes MemRegion::getAsOffset's use of ASTRecordLayout when redeclarations are involved. llvm-svn: 175913

* Replace some typically large vectors with SmallVector.Benjamin Kramer2013-02-223-7/+7
| | | | | | | | This may seem counter-intuitive but the POD-like optimization helps when the vectors grow into multimegabyte buffers. SmallVector calls realloc which knows how to twiddle virtual memory bits and avoids large copies. llvm-svn: 175906

* Suppress -Wswitch to unbreak the build.David Blaikie2013-02-221-0/+1
| | | | | | | This may need to be fixed more intelligently - I don't have enough context to be sure what the appropriate fix is right now. llvm-svn: 175902
* [Sema] Semantic analysis for empty-declaration and attribute-declaration.Michael Han2013-02-2219-32/+81
| | | | | | | | 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

* Comment parsing: add CommentOptions to allow specifying custom comment block ↵Dmitri Gribenko2013-02-2215-9/+240
| | | | | | | | | | | | | | | | commands Add an ability to specify custom documentation block comment commands via a new class CommentOptions. The intention is that this class will hold future customizations for comment parsing, including defining documentation comments with specific numbers of parameters, etc. CommentOptions instance is a member of LangOptions. CommentOptions is controlled by a new command-line parameter -fcomment-block-commands=Foo,Bar,Baz. llvm-svn: 175892

| | | | | | | | | | | | | | | | | | | | | | | | accessible in its declaring class; otherwise we might fail to apply [class.protected] when considering accessibility in derived classes. Noticed by inspection; <rdar://13270329>. I had an existing test wrong. Here's why it's wrong: Follow the rules (and notation) of [class.access]p5. The naming class (N) is B and the context (R) is D::getX. - 'x' as a member of B is protected, but R does not occur in a member or friend of a class derived from B. - There does exist a base class of B, A, which is accessible from R, and 'x' is accessible at R when named in A because 'x' as a member of A is protected and R occurs in a member of a class, D, that is derived from A; however, by [class.protected], the class of the object expression must be equal to or derived from that class, and A does not derive from D. llvm-svn: 175858
* [analyzer] Place all inlining policy checks into one palceAnna Zaks2013-02-223-176/+184
| | | | | | | | | | | | | Previously, we had the decisions about inlining spread out over multiple functions. In addition to the refactor, this commit ensures that we will always inline BodyFarm functions as long as the Decl is available. This fixes false positives due to those functions not being inlined when no or minimal inlining is enabled such (as shallow mode). llvm-svn: 175857
* Add -fbracket-depth=N, analogous to -ftemplate-depth= and -fconstexpr-depth=,Richard Smith2013-02-2210-5/+37
| | | | | | | | | | | 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
* [analyzer] Make sure a materialized temporary matches its bindings.Jordan Rose2013-02-225-52/+64
| | | | | | | | | | | | | | | | | This is a follow-up to r175830, which made sure a temporary object region created for, say, a struct rvalue matched up with the initial bindings being stored into it. This does the same for the case in which the AST actually tells us that we need to create a temporary via a MaterializeObjectExpr. I've unified the two code paths and moved a static helper function onto ExprEngine. This also caused a bit of test churn, causing us to go back to describing temporary regions without a 'const' qualifier. This seems acceptable; it's our behavior from a few months ago. <rdar://problem/13265460> (part 2) llvm-svn: 175854

* Preproceessor: fix #if skipping under -traditional-cpp.Jordan Rose2013-02-222-1/+17
| | | | | | | | | | | | When parsing directives within skipped #if blocks, we don't want to retain any whitespace. Previously we were just skipping comments, but it's not possible to skip comments and retain other whitespace. This change matches the usual behavior for parsing directives (i.e. the behavior outside of skipped #if blocks). <rdar://problem/13267695> llvm-svn: 175840

* [analyzer] Make sure a temporary object region matches its initial bindings.Jordan Rose2013-02-212-4/+57
| | | | | | | | | | | | | | | | When creating a temporary region (say, when a struct rvalue is used as the base of a member expr), make sure we account for any derived-to-base casts. We don't actually record these in the LazyCompoundVal that represents the rvalue, but we need to make sure that the temporary region we're creating (a) matches the bindings, and (b) matches its expression. Most of the time this will do exactly the same thing as before, but it fixes spurious "garbage value" warnings introduced in r175234 by the use of lazy bindings to model trivial copy constructors. <rdar://problem/13265460> llvm-svn: 175830
