2009-11-05Make LookUpIdentifierInfo const. This makes the Identifiers table mutable and isDaniel Dunbar
a little fuzzy, but conceptually it's just uniquing the identifier. Chris, please review. I debated splitting into const/non-const versions where the const one propogated constness to the resulting IdentifierInfo*. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86106 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-16Add support for a chain of stat caches in the FileManager, rather thanDouglas Gregor
only supporting a single stat cache. The immediate benefit of this change is that we can now generate a PCH/AST file when including another PCH file; in the future, the chain of stat caches will likely be useful with multiple levels of PCH files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84263 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-22Replace the -code-completion-dump option with Douglas Gregor
-code-completion-at=filename:line:column which performs code completion at the specified location by truncating the file at that position and enabling code completion. This approach makes it possible to run multiple tests from a single test file, and gives a more natural command-line interface. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82571 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-17Initial implementation of a code-completion interface in Clang. InDouglas Gregor
essence, code completion is triggered by a magic "code completion" token produced by the lexer [*], which the parser recognizes at certain points in the grammar. The parser then calls into the Action object with the appropriate CodeCompletionXXX action. Sema implements the CodeCompletionXXX callbacks by performing minimal translation, then forwarding them to a CodeCompletionConsumer subclass, which uses the results of semantic analysis to provide code-completion results. At present, only a single, "printing" code completion consumer is available, for regression testing and debugging. However, the design is meant to permit other code-completion consumers. This initial commit contains two code-completion actions: one for member access, e.g., "x." or "p->", and one for nested-name-specifiers, e.g., "std::". More code-completion actions will follow, along with improved gathering of code-completion results for the various contexts. [*] In the current -code-completion-dump testing/debugging mode, the file is truncated at the completion point and EOF is translated into "code completion". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82166 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-02Add support for retrieving the Doxygen comment associated with a givenDouglas Gregor
declaration in the AST. The new ASTContext::getCommentForDecl function searches for a comment that is attached to the given declaration, and returns that comment, which may be composed of several comment blocks. Comments are always available in an AST. However, to avoid harming performance, we don't actually parse the comments. Rather, we keep the source ranges of all of the comments within a large, sorted vector, then lazily extract comments via a binary search in that vector only when needed (which never occurs in a "normal" compile). Comments are written to a precompiled header/AST file as a blob of source ranges. That blob is only lazily loaded when one requests a comment for a declaration (this never occurs in a "normal" compile). The indexer testbed now supports comment extraction. When the -point-at location points to a declaration with a Doxygen-style comment, the indexer testbed prints the associated comment block(s). See test/Index/comments.c for an example. Some notes: - We don't actually attempt to parse the comment blocks themselves, beyond identifying them as Doxygen comment blocks to associate them with a declaration. - We won't find comment blocks that aren't adjacent to the declaration, because we start our search based on the location of the declaration. - We don't go through the necessary hops to find, for example, whether some redeclaration of a declaration has comments when our current declaration does not. Similarly, we don't attempt to associate a \param Foo marker in a function body comment with the parameter named Foo (although that is certainly possible). - Verification of my "no performance impact" claims is still "to be done". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74704 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-16my refactoring of builtins changed target-specific builtins to only beChris Lattner
registered when PCH wasn't being used. We should always install (in BuiltinInfo) information about target-specific builtins, but we shouldn't register any builtin identifier infos. This fixes the build of apps that use PCH and target specific builtins together. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73492 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-14Change Lexer::MeasureTokenLength to take a LangOptions reference.Chris Lattner
This allows it to accurately measure tokens, so that we get: t.cpp:8:13: error: unknown type name 'X' static foo::X P; ~~~~~^ instead of the woefully inferior: t.cpp:8:13: error: unknown type name 'X' static foo::X P; ~~~~ ^ Most of this is just plumbing to push the reference around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69099 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-10Compare the predefines buffer in the PCH file with the predefinesDouglas Gregor
buffer generated for the current translation unit. If they are different, complain and then ignore the PCH file. This effectively checks for all compilation options that somehow would affect preprocessor state (-D, -U, -include, the dreaded -imacros, etc.). When we do accept the PCH file, throw away the contents of the predefines buffer rather than parsing them, since all of the results of that parsing are already stored in the PCH file. This eliminates the ugliness with the redefinition of __builtin_va_list, among other things. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68838 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-10do a dance with predefines, and finally enable reading of macros fromChris Lattner
PCH. This works now, except for limitations not being able to do things with identifiers. The basic example in the testcase works though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68832 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-10move a bunch of code for initializing the predefines buffer out of ↵Chris Lattner
Preprocessor.cpp into clang-cc.cpp. This makes it so clang-cc constructs the *entire* predefines buffer, not just half of it. A bonus of this is that we get to kill a copy of DefineBuiltinMacro. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68830 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-10PCH serialization/deserialization of the source manager. With thisDouglas Gregor
improvement, source locations read from the PCH file will properly resolve to the source files that were used to build the PCH file itself. Once we have the preprocessor state stored in the PCH file, source locations that refer to macro instantiations that occur in the PCH file should have the appropriate instantiation information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68758 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-08More fixes to builtin preprocessor defines.Daniel Dunbar
- Add -static-define option driver can use when __STATIC__ should be defined (instead of __DYNAMIC__). - Don't set __OPTIMIZE_SIZE__ on Os, __OPTIMIZE_SIZE__ is tied to Oz. - Set __NO_INLINE__ following GCC 4.2. - Set __GNU_GNU_INLINE__ or __GNU_STDC_INLINE__ following GCC 4.2. - Set __EXCEPTIONS for Objective-C NonFragile ABI. - Set __STRICT_ANSI__ for standard conforming modes. - I added a clang style test case in utils for this, but its not particularly portable and I don't think it belongs in the test suite. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68621 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-08Set __PIC__ (more) correctly.Daniel Dunbar
- Add -pic-level clang-cc option to specify the value for the define, updated driver to pass this. - Added __pic__ - Added OBJC_ZEROCOST_EXCEPTIONS define while I was here (to match gcc). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68584 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07The __weak and __strong defines are common to all darwin targetsChris Lattner

2009-02-15track "just a little more" location information for macro instantiations.Chris Lattner
Now instead of just tracking the expansion history, also track the full range of the macro that got replaced. For object-like macros, this doesn't change anything. For _Pragma and function-like macros, this means we track the locations of the ')'. This is required for PR3579 because apparently GCC uses the line of the ')' of a function-like macro as the location to expand __LINE__ to. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64601 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-13Fix rdar://6562329, a static analyzer crash Ted noticed on Chris Lattner
wine sources. This was happening because HighlightMacros was calling EnterMainFile multiple times on the same preprocessor object and getting an assert due to the new #line stuff (the file in question was bison output with #line directives). The fix for this is to not reenter the file. Instead, relex the tokens in raw mode, swizzle them a bit and repreprocess the token stream. An added bonus of this is that rewrite macros will now hilight the macro definition as well as its uses. Woo. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64480 91177308-0d34-0410-b5e6-96231b3b80d8
