ASTContext. Fixes some cases where we could previously initialize the AST consumer more than once. llvm-svn: 245346
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 Prantl1-2/+4
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

2014-08-10Recommit 213307: unique_ptr-ify ownership of ASTConsumers (reverted in r213325)David Blaikie1-2/+2
After post-commit review and community discussion, this seems like a reasonable direction to continue, making ownership semantics explicit in the source using the type system. llvm-svn: 215323

2014-07-17Revert "unique_ptr-ify ownership of ASTConsumers"David Blaikie1-2/+2
This reverts commit r213307. Reverting to have some on-list discussion/confirmation about the ongoing direction of smart pointer usage in the LLVM project. llvm-svn: 213325
2014-07-17unique_ptr-ify ownership of ASTConsumersDavid Blaikie1-2/+2
(after fixing a bug in MultiplexConsumer I noticed the ownership of the nested consumers was implemented with raw pointers - so this fixes that... and follows the source back to its origin pushing unique_ptr ownership up through there too) llvm-svn: 213307

2013-05-03When building a module, forward diagnostics to the outer diagnostic consumer.Douglas Gregor1-3/+4
Previously, we would clone the current diagnostic consumer to produce a new diagnostic consumer to use when building a module. The problem here is that we end up losing diagnostics for important diagnostic consumers, such as serialized diagnostics (where we'd end up with two diagnostic consumers writing the same output file). With forwarding, the diagnostics from all of the different modules being built get forwarded to the one serialized-diagnostic consumer and are emitted in a sane way. Fixes <rdar://problem/13663996>. llvm-svn: 181067
2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth1-2/+2
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
2012-10-23Make DiagnosticOptions intrusively reference-counted, and make sureDouglas Gregor1-2/+3
the various stakeholders bump up the reference count. In particular, the diagnostics engine now keeps the DiagnosticOptions object alive. llvm-svn: 166508

(Lex to AST). The member variable is always "LangOpts" and the member function is always "getLangOpts". Reviewed by Chris Lattner llvm-svn: 152536
2012-02-20Basic: import IntrusiveRefCntPtr<> into clang namespaceDylan Noblesmith1-2/+2

2011-08-25Introduce a -cc1 option "-emit-module", that creates a binary moduleDouglas Gregor1-2/+2
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. llvm-svn: 138595

2010-11-18Refactoring of Diagnostic class.Argyrios Kyrtzidis1-9/+15
-Move the stuff of Diagnostic related to creating/querying diagnostic IDs into a new DiagnosticIDs class. -DiagnosticIDs can be shared among multiple Diagnostics for multiple translation units. -The rest of the state in Diagnostic object is considered related and tied to one translation unit. -Have Diagnostic point to the SourceManager that is related with. Diagnostic can now accept just a SourceLocation instead of a FullSourceLoc. -Reflect the changes to various interfaces. llvm-svn: 119730
2010-11-03Implement -working-directory.Argyrios Kyrtzidis1-2/+5
When -working-directory is passed in command line, file paths are resolved relative to the specified directory. This helps both when using libclang (where we can't require the user to actually change the working directory) and to help reproduce test cases when the reproduction work comes along. --FileSystemOptions is introduced which controls how file system operations are performed (currently it just contains the working directory value if set). --FileSystemOptions are passed around to various interfaces that perform file operations. --Opening & reading the content of files should be done only through FileManager. This is useful in general since file operations will be abstracted in the future for the reproduction mechanism. FileSystemOptions is independent of FileManager so that we can have multiple translation units sharing the same FileManager but with different FileSystemOptions.

2010-04-05Clarify the ownership semantics of the Diagnostic object used byDouglas Gregor1-1/+2

2010-02-11When AST merging for record declarations fails, warn about theDouglas Gregor1-9/+4
incompatibility and show where the structural differences are. For example: struct1.c:36:8: warning: type 'struct S7' has incompatible definitions in different translation units struct S7 { int i : 8; unsigned j : 8; } x7; ^ struct1.c:36:33: note: bit-field 'j' with type 'unsigned int' and length 8 here struct S7 { int i : 8; unsigned j : 8; } x7; ^ struct2.c:33:33: note: bit-field 'j' with type 'unsigned int' and length 16 here struct S7 { int i : 8; unsigned j : 16; } x7; ^ There are a few changes to make this work: - ASTImporter now has only a single Diagnostic object, not multiple diagnostic objects. Otherwise, having a warning/error printed via one Diagnostic and its note printed on the other Diagnostic could cause the note to be suppressed. - Implemented import functionality for IntegerLiteral (along with general support for statements and expressions) llvm-svn: 95900

Here's an example error that involves a conflict merging a variable with different types in two translation units (diagnosed in the third AST context into which everything is merged). /Volumes/Data/dgregor/Projects/llvm/tools/clang/test/ASTMerge/Inputs/var2.c:3:5: error: external variable 'x2' declared with incompatible types in different translation units ('int' vs. 'double') int x2; ^ In file included from /Volumes/Data/dgregor/Projects/llvm/tools/clang/test/ASTMerge/Inputs/var1.c:3: /Volumes/Data/dgregor/Projects/llvm/tools/clang/test/ASTMerge/Inputs/var1.h:1:8: note: declared here with type 'double' double x2; ^ Although we maintain include history, we do not maintain macro instantiation history across a merge.
