2015-11-03Introduce module file extensions to piggy-back data onto module files.Douglas Gregor1-1/+4
Introduce the notion of a module file extension, which introduces additional information into a module file at the time it is built that can then be queried when the module file is read. Module file extensions are identified by a block name (which must be unique to the extension) and can write any bitstream records into their own extension block within the module file. When a module file is loaded, any extension blocks are matched up with module file extension readers, that are per-module-file and are given access to the input bitstream. Note that module file extensions can only be introduced by programmatic clients that have access to the CompilerInvocation. There is only one such extension at the moment, which is used for testing the module file extension harness. As a future direction, one could imagine allowing the plugin mechanism to introduce new module file extensions. llvm-svn: 251955

useless return value. Switch to using it directly when completing the redeclaration chain for an anonymous declaration, and reduce the set of declarations that we load in the process to just those of the right kind. llvm-svn: 244161
2015-07-17Make the clang module container format selectable from the command line.Adrian Prantl1-1/+1
- introduces a new cc1 option -fmodule-format=[raw,obj] with 'raw' being the default - supports arbitrary module container formats that libclang is agnostic to - adds the format to the module hash to avoid collisions - splits the old PCHContainerOperations into PCHContainerWriter and a PCHContainerReader. Thanks to Richard Smith for reviewing this patch! llvm-svn: 242499

2015-06-20Introduce a PCHContainerOperations interface (NFC).Adrian Prantl1-9/+13
A PCHContainerOperations abstract interface provides operations for creating and unwrapping containers for serialized ASTs (precompiled headers and clang modules). The default implementation is RawPCHContainerOperations, which uses a flat file for the output. The main application for this interface will be an ObjectFilePCHContainerOperations implementation that uses LLVM to wrap the module in an ELF/Mach-O/COFF container to store debug info alongside the AST. rdar://problem/20091852 llvm-svn: 240225

2015-03-24[modules] Deserialize CXXCtorInitializer list for a constructor lazily.Richard Smith1-0/+5
Previously we'd deserialize the list of mem-initializers for a constructor when we deserialized the declaration of the constructor. That could trigger a significant amount of unnecessary work (pulling in all base classes recursively, for a start) and was causing problems for the modules buildbot due to cyclic deserializations. We now deserialize these on demand. This creates a certain amount of duplication with the handling of CXXBaseSpecifiers; I'll look into reducing that next. llvm-svn: 233052

2015-02-25Wrap clang module files in a Mach-O, ELF, or COFF container.Adrian Prantl1-6/+10
This is a necessary prerequisite for debugging with modules. The .pcm files become containers that hold the serialized AST which allows us to store debug information in the module file that can be shared by all object files that were built importing the module. This reapplies r230044 with a fixed configure+make build and updated dependencies and testcase requirements. Over the last iteration this version adds - missing target requirements for testcases that specify an x86 triple, - a missing clangCodeGen.a dependency to libClang.a in the make build. rdar://problem/19104245 llvm-svn: 230423

ASTUnit::getMainBufferWithPrecompiledPreamble(). With r197755 we started reading the contents of buffer file entries, but the buffers may point to ASTReader blobs that have been disposed. Fix this by having the CompilerInstance object keep a reference to the ASTReader as well as having the ASTContext keep reference to the ExternalASTSource.

2013-03-19<rdar://problem/13363214> Eliminate race condition between module rebuild ↵Douglas Gregor1-0/+1
and the global module index. The global module index was querying the file manager for each of the module files it knows about at load time, to prune out any out-of-date information. The file manager would then cache the results of the stat() falls used to find that module file. Later, the same translation unit could end up trying to import one of the module files that had previously been ignored by the module cache, but after some other Clang instance rebuilt the module file to bring it up-to-date. The stale stat() results in the file manager would trigger a second rebuild of the already-up-to-date module, causing failures down the line. The global module index now lazily resolves its module file references to actual AST reader module files only after the module file has been loaded, eliminating the stat-caching race. Moreover, the AST reader can communicate to its caller that a module file is missing (rather than simply being out-of-date), allowing us to simplify the module-loading logic and allowing the compiler to recover if a dependent module file ends up getting deleted. llvm-svn: 177367
2013-02-07Simplify FindExternalVisibleDeclsByName by making it return a bool indicatingRichard Smith1-1/+1
if it found any decls, rather than returning a list of found decls. This removes a returning-ArrayRef-to-deleted-storage bug from MultiplexExternalSemaSource (in code not exercised by any of the clang binaries), reduces the work required in the found-no-decls case with PCH, and importantly removes the need for DeclContext::lookup to be reentrant. No functionality change intended! llvm-svn: 174576
2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth1-5/+5
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. 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

2012-10-09Rework the (de-)serialization of macros, as stored inDouglas Gregor1-0/+2
MacroInfo*. Instead of simply dumping an offset into the current file, give each macro definition a proper ID with all of the standard modules-remapping facilities. Additionally, when a macro is modified in a subsequent AST file (e.g., #undef'ing a macro loaded from another module or from a precompiled header), provide a macro update record rather than rewriting the entire macro definition. This gives us greater consistency with the way we handle declarations, and ties together macro definitions much more cleanly. Note that we're still not actually deserializing macro history (we never were), but it's far easy to do properly now. llvm-svn: 165560
