2013-03-27<rdar://problem/13509689> Introduce -module-file-info option that provides ↵Douglas Gregor
information about a particular module file. This option can be useful for end users who want to know why they ended up with a ton of different variants of the "std" module in their module cache. This problem should go away over time, as we reduce the need for module variants, but it will never go away entirely. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178148 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-28Enable the global module index by default. Introduce theDouglas Gregor
-fno-modules-global-index -cc1 option to allow one to disable the index for performance testing purposes, but with a 10% win in -fsyntax-only time, there is no reason a user would do this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173707 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-25Rename the -cc1 option "-generate-module-index" toDouglas Gregor
"-fmodules-global-index" and expand its behavior to include both the use and generation of the global module index. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173404 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-23Implement the writer side of the global module index. Douglas Gregor
The global module index is a "global" index for all of the module files within a particular subdirectory in the module cache, which keeps track of all of the "interesting" identifiers and selectors known in each of the module files. One can perform a fast lookup in the index to determine which module files will have more information about entities with a particular name/selector. This information can help eliminate redundant lookups into module files (a serious performance problem) and help with creating auto-import/auto-include Fix-Its. The global module index is created or updated at the end of a translation unit that has triggered a (re)build of a module by scraping all of the .pcm files out of the module cache subdirectory, so it catches everything. As with module rebuilds, we use the file system's atomicity to synchronize. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173301 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-21Switch FrontendOptions to using an initializer list rather than initializingRichard Smith
the values in the constructor. The constructor implementation is trivial beyond the value initialisations. Patch by Saleem Abdulrasool! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170929 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-02Add a new libclang completion API to get brief documentation comment that isDmitri Gribenko
attached to a declaration in the completion string. Since extracting comments isn't free, a new code completion option is introduced. A new code completion option that enables including brief comments into CodeCompletionString should be a, err, code completion option. But because ASTUnit caches global declarations during parsing before even completion consumer is created, the option is duplicated as a translation unit option (in both libclang and ASTUnit, like the option to cache code completion results). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159539 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-13More doxygen/documentation cleanups.James Dennett
This reduces the number of warnings generated by Doxygen by about 100 (roughly 10%). Issues addressed: (1) Primarily, backslash-escaped "@foo" and "#bah" in Doxygen comments when they're not supposed to be Doxygen commands or links, and similarly for "<baz>" when it's not intended as as HTML tag; (2) Changed some \t commands (which don't exist) to \c ("to refer to a word of code", as the Doxygen manual says); (3) \precondition becomes \pre; (4) When touching comments, deleted a couple of spurious spaces in them; (5) Changed some \n and \r to \\n and \\r; (6) Fixed one tiny typo: #pragms -> #pragma. This patch touches documentation/comments only. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158422 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-06Add a -rewrite-includes option, which is similar to -rewrite-macros, but ↵David Blaikie
only expands #include directives. Patch contributed by Lubos Lunak (l.lunax@suse.cz). Review by Matt Beaumont-Gay (matthewbg@google.com). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158093 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-13Remove the -cc1-level option "-pubnames-dump". Such things should stayDouglas Gregor
out of the tree and use the tooling infrastructure. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154668 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-12Added a flag to the parser to skip method bodies.Erik Verbruggen

2012-03-27Introduce a -cc1-level option -pubnames-dump, which simply dumps theDouglas Gregor
list of identifiers that that 'public' names at the end of the translation unit, e.g., defined macros or identifiers with top-level names, in sorted order. Meant to support <rdar://problem/10921596>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153522 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-06Add new code migrator support for migrating existing Objective-C code to useTed Kremenek
the new Objective-C NSArray/NSDictionary/NSNumber literal syntax. This introduces a new library, libEdit, which provides a new way to support migration of code that improves on the original ARC migrator. We now believe that most of its functionality can be refactored into the existing libraries, and thus this new library may shortly disappear. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152141 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-27Introduce module attributes into the module map grammar, along with aDouglas Gregor
single attribute ("system") that allows us to mark a module as being a "system" module. Each of the headers that makes up a system module is considered to be a system header, so that we (for example) suppress warnings there. If a module is being inferred for a framework, and that framework directory is within a system frameworks directory, infer it as a system framework. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149143 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-26Extend the ExternalASTSource interface to allow the AST source toDouglas Gregor
provide the layout of records, rather than letting Clang compute the layout itself. LLDB provides the motivation for this feature: because various layout-altering attributes (packed, aligned, etc.) don't get reliably get placed into DWARF, the record layouts computed by LLDB from the reconstructed records differ from the actual layouts, and badness occurs. This interface lets the DWARF data drive layout, so we don't need the attributes preserved to get the answer write. The testing methodology for this change is fun. I've introduced a variant of -fdump-record-layouts called -fdump-record-layouts-simple that always has the simple C format and provides size/alignment/field offsets. There is also a -cc1 option -foverride-record-layout=<file> to take the output of -fdump-record-layouts-simple and parse it to produce a set of overridden layouts, which is introduced into the AST via a testing-only ExternalASTSource (called LayoutOverrideSource). Each test contains a number of records to lay out, which use various layout-changing attributes, and then dumps the layouts. We then run the test again, using the preprocessor to eliminate the layout-changing attributes entirely (which would give us different layouts for the records), but supplying the previously-computed record layouts. Finally, we diff the layouts produced from the two runs to be sure that they are identical. Note that this code makes the assumption that we don't *have* to provide the offsets of bases or virtual bases to get the layout right, because the alignment attributes don't affect it. I believe this assumption holds, but if it does not, we can extend LayoutOverrideSource to also provide base offset information. Fixes the Clang side of <rdar://problem/10169539>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149055 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-26Introduce 3 new fixit options:Argyrios Kyrtzidis
-fixit-recompile applies fixits and recompiles the result -fixit-to-temporary applies fixits to temporary files -fix-only-warnings">, applies fixits for warnings only, not errors Combining "-fixit-recompile -fixit-to-temporary" allows testing the result of fixits without touching the original sources. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149027 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-20Extract the (InputKind, std::string) pair used to describe inputs toDouglas Gregor
the front end into its own class, FrontendInputFile, to make it easier to introduce new per-input data. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148546 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-29Eliminate the -emit-module option, which emitted a module by parsing aDouglas Gregor
source file (e.g., a header). Immediately steal this useful option name for building modules from a module map file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145444 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-16Add support for building a module from a module map to the -cc1Douglas Gregor
interface. This is currently limited to modules with umbrella headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144736 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-25Eliminate the -chained-pch flag and all of the frontend and libclang options ↵Douglas Gregor
associated with it. Chained PCH is the only way to build a PCH file that includes another PCH file git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138597 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-25Introduce a -cc1 option "-emit-module", that creates a binary moduleDouglas Gregor
from the given source. -emit-module behaves similarly to -emit-pch, except that Sema is somewhat more strict about the contents of -emit-module. In the future, there are likely to be more interesting differences. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138595 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-20now that we have a centralized place to do so, add some using declarations forChris Lattner
some common llvm types: stringref and smallvector. This cleans up the codebase quite a bit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135576 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-19[arcmt] Add some additional driver flags to optionally emit or save the ↵Argyrios Kyrtzidis
pre-migration ARC errors. -arcmt-migrate-emit-errors : Emits the pre-migration ARC errors but it doesn't affect anything else -arcmt-migrate-report-output : Writes out the pre-migration ARC errors to the provided plist file rdar://9791454 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135491 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-09[arcmt] Introduce new '-ccc-arcmt-migrate <path>' ARC migration driver option.Argyrios Kyrtzidis
This is a new mode of migration, where we avoid modifying the original files but we emit temporary files instead. <path> will be used to keep migration process metadata. Currently the temporary files that are produced are put in the system's temp directory but we can put them in the <path> if is necessary. Also introduce new ARC migration functions in libclang whose only purpose, currently, is to accept <path> and provide pairs of original file/transformed file to map from the originals to the files after transformations are applied. Finally introduce the c-arcmt-test utility that exercises the new libclang functions, update arcmt-test, and add tests for the whole process. rdar://9735086. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134844 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-15Automatic Reference Counting.John McCall

2011-03-07Remove the AST printer (-ast-print-xml), which is too incomplete andDouglas Gregor
too low-level to actually be useful but is just interesting enough for people to try to use it (which won't actually work beyond toy examples). To bring back the AST printer, it needs to be: - Complete, covering all of C/C++/Objective-C - Documented, with appropriate Schema against which we can validate the output - Designed for C/C++/Objective-C, not Clang's specific ASTs - Stable across Clang versions - Well-tested git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127141 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-17Eliminate the internal command-line option for viewing inheritance in C++ ↵Douglas Gregor
classes, since it's only really worked for the trivial cases anyway due to lame pseudo-parsing of the class name. The viewInheritance() function is still available for use in the debugger, where this is far more useful git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125762 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-24Add -cc1 -ast-dump-xml, an excessively detailed XML dump of the internalsJohn McCall
of the ASTs. Only available in assertions builds. No stability guarantee. This is intended solely as a debugging tool. I'm not sure if the goals are sufficiently aligned with the XML printer to allow a common implementation. Currently just falls back on the StmtDumper to display statements, which means it doesn't produce valid XML in those cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120088 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-15Extend the code-completion caching infrastructure to include globalDouglas Gregor
declarations (in addition to macros). Each kind of declaration maps to a certain set of completion contexts, and the ASTUnit completion logic introduces the completion strings for those declarations if the actual code-completion occurs in one of the contexts where it matters. There are a few new code-completion-context kinds. Without these, certain completions (e.g., after "using namespace") would need to suppress all global completions, which would be unfortunate. Note that we don't get the priorities right for global completions, because we don't have enough type information. We'll need a way to compare types in an ASTContext-agnostic way before this can be implemented. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111093 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-20Introduce a new lexer function to compute the "preamble" of a file,Douglas Gregor
which is the part of the file that contains all of the initial comments, includes, and preprocessor directives that occur before any of the actual code.

2010-07-09Add a frontend option -chained-pch and don't pass an active PCH reader to ↵Sebastian Redl
the PCH writer if it is not set, preventing creation of chained PCH files. Since the reader is so far unused, effectively no functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107936 91177308-0d34-0410-b5e6-96231b3b80d8
