2013-02-23Shrink SmallPtrSet. It gets swapped a lot which copies the whole small part.Benjamin Kramer
Testing shows that it's empty in >99% of the cases and I couldn't find a case where it contained more than 2 elements. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175967 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-23Don't recognize unnamed pointer parameters as casts.Daniel Jasper
This fixes llvm.org/PR15061. Before: virtual void f(int *)const; After: virtual void f(int *) const; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175960 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-23Allow splitting between string literals and identifiers.Daniel Jasper
Also don't break in long include directives as that is not desired. We can now format: #include "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaa" #define LL_FORMAT "ll" printf("aaaaa: %d, bbbbbbbbb: %" LL_FORMAT "d, cccccccc: %" LL_FORMAT "d, ddddddddd: %" LL_FORMAT "d\n"); Before, this led to weird results. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175959 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-23Remove the CFGElement "Invalid" state.David Blaikie
Use Optional<CFG*> where invalid states were needed previously. In the one case where that's not possible (beginAutomaticObjDtorsInsert) just use a dummy CFGAutomaticObjDtor. Thanks for the help from Jordan Rose & discussion/feedback from Ted Kremenek and Doug Gregor. Post commit code review feedback on r175796 by Ted Kremenek. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175938 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-23Remove the hack that avoided mangling static functions in extern C contexts.Rafael Espindola
Weather we should give C language linkage to functions and variables with internal linkage probably depends on how much code assumes it. The standard says they should have no language linkage, but gcc and msvc assign them C language linkage. This commit removes the hack that was preventing the mangling on static functions declare in extern C contexts. It is an experiment to see if we can implement the rules in the standard. If it turns out that many users depend on these functions and variables having C language linkage, we should change isExternC instead and try to convince the CWG to change the standard. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175937 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-22Propagate the split dwarf file information through into the backendEric Christopher
and through to the debug info in the module. In order to make the testcase a bit more efficient allow the filename to go through compilation for compile and not assemble jobs and turn off the extract for cases where we don't create an object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175935 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-22Driver: Pass down the -march setting down to -cc1as on x86 too.Benjamin Kramer
The assembler historically didn't make use of any target features, but this has changed when support for old CPUs that don't support long nops was added. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175919 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-22Make sure we apply attributes to correct places.Bill Wendling
Some attributes make sense only on the function or on the call site, but not both. Make this distinction here. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175918 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175916 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-22[analyzer] Don't canonicalize the RecordDecl used in CXXBaseObjectRegion.Jordan Rose
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175913 91177308-0d34-0410-b5e6-96231b3b80d8

MacroDefinition object instead its index in the preprocessed entities vector. This is because the order of the entities in the vector can change in some (uncommon) cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175907 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-22Replace some typically large vectors with SmallVector.Benjamin Kramer
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175906 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-22[Sema] Semantic analysis for empty-declaration and attribute-declaration.Michael Han
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175900 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-22Comment parsing: add CommentOptions to allow specifying custom comment block ↵Dmitri Gribenko
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175892 91177308-0d34-0410-b5e6-96231b3b80d8
