* [clang] Update uses of DEBUG macro to LLVM_DEBUG.Nicola Zaghen2018-05-151-1/+1
| | | | | | | | | | | | | The DEBUG() macro is very generic so it might clash with other projects. The renaming was done as follows: - git grep -l 'DEBUG' | xargs sed -i 's/\bDEBUG\s\?(/LLVM_DEBUG(/g' - git diff -U0 master | ../clang/tools/clang-format/clang-format-diff.py -i -p1 -style LLVM Explicitly avoided changing the strings in the clang-format tests.

* -gmodules: Emit debug info for implicit module imports via #include.Adrian Prantl2018-01-031-0/+5
| | | | | | | | | | | | When a type is only used as a template parameter and that type is the only type imported from another #include'd module, no skeleton CU for that module is generated, so a consumer doesn't know where to find the type definition. By emitting an import declaration, we can force a skeleton CU to be generated for each imported module. rdar://problem/36266156 llvm-svn: 321754

* Debug Info: Set the MainFileName when generating -gmodules debug info for PCM.Adrian Prantl2017-07-181-0/+3
| | | | | | | Previously it was uninitialized and thus always defaulted to "<stdin>". This is mostly a cosmetic change that helps making the debug info more readable. llvm-svn: 308397
* Modules: Use hash of PCM content for SIGNATUREDuncan P. N. Exon Smith2017-03-131-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Change ASTFileSignature from a random 32-bit number to the hash of the PCM content. - Move definition ASTFileSignature to Basic/Module.h so Module and ASTSourceDescriptor can use it. - Change the signature from uint64_t to std::array<uint32_t,5>. - Stop using (saving/reading) the size and modification time of PCM files when there is a valid SIGNATURE. - Add UNHASHED_CONTROL_BLOCK, and use it to store the SIGNATURE record and other records that shouldn't affect the hash. Because implicit modules reuses the same file for multiple levels of -Werror, this includes DIAGNOSTIC_OPTIONS and DIAG_PRAGMA_MAPPINGS. This helps to solve a PCH + implicit Modules dependency issue: PCH files are handled by the external build system, whereas implicit modules are handled by internal compiler build system. This prevents invalidating a PCH when the compiler overwrites a PCM file with the same content (modulo the diagnostic differences). Design and original patch by Manman Ren! llvm-svn: 297655
* CodeGen: plumb header search down to the IASSaleem Abdulrasool2017-01-051-4/+5
| | | | | | | | | | | inline assembly may use the `.include` directive to include other content into the file. Without the integrated assembler, the `-I` group gets passed to the assembler. Emulate this by collecting the header search paths and passing them to the IAS. Resolves PR24811! llvm-svn: 291123
* Bitcode: Decouple block info block state from reader.Peter Collingbourne2016-11-081-7/+7
| | | | | | | | | | | | | | | | | As proposed on llvm-dev: http://lists.llvm.org/pipermail/llvm-dev/2016-October/106630.html Move block info block state to a new class, BitstreamBlockInfo. Clients may set the block info for a particular cursor with the BitstreamCursor::setBlockInfo() method. At this point BitstreamReader is not much more than a container for an ArrayRef<uint8_t>, so remove it and replace all uses with direct uses of memory buffers. Differential Revision: https://reviews.llvm.org/D26259 llvm-svn: 286207
* Bitcode: Change reader interface to take memory buffers.Peter Collingbourne2016-11-021-4/+3
| | | | | | | | | | | | | | | | | | | As proposed on llvm-dev: http://lists.llvm.org/pipermail/llvm-dev/2016-October/106595.html This change also fixes an API oddity where BitstreamCursor::Read() would return zero for the first read past the end of the bitstream, but would report_fatal_error for subsequent reads. Now we always report_fatal_error for all reads past the end. Updated clients to check for the end of the bitstream before reading from it. I also needed to add padding to the invalid bitcode tests in test/Bitcode/. This is because the streaming interface was not checking that the file size is a multiple of 4.

* Support object-file-wrapped modules in clang -module-file-info.Adrian Prantl2016-08-171-13/+17

* Frontend: Simplify ownership model for clang's output streams.Peter Collingbourne2016-07-151-15/+14
| | | | | | | | | | | | | | This changes the CompilerInstance::createOutputFile function to return a std::unique_ptr<llvm::raw_ostream>, rather than an llvm::raw_ostream implicitly owned by the CompilerInstance. This in most cases required that I move ownership of the output stream to the relevant ASTConsumer. The motivation for this change is to allow BackendConsumer to be a client of interfaces such as D20268 which take ownership of the output stream.

* [modules][debuginfo] Only include imported modules when targeting LLDBDavid Blaikie2016-05-031-0/+1
| | | | | | | | | | | | | | | | | These constructs are only applicable to a debugger capable of loading a Clang AST, so omit them for brevity when not doing so. We could potentially propagate more of CodeGenOptions through the ObjectFilePCGContainerOperations for consistency (so the next person who adds some CodeGenOpts feature that tweaks debug info output doesn't get caught by this), so I'm open to objections/alternatives there, but went with this for now. Tested just a couple of basic cases (one direct, one indirect (through the ObjectFilePCHContainerOperations) & fixed up other cases to pass the -debugger-tuning flag as appropriate. llvm-svn: 268460
* revert SVN r265702, r265640Saleem Abdulrasool2016-04-081-2/+1
| | | | | | | | | | | Revert the two changes to thread CodeGenOptions into the TargetInfo allocation and to fix the layering violation by moving CodeGenOptions into Basic. Code Generation is arguably not particularly "basic". This addresses Richard's post-commit review comments. This change purely does the mechanical revert and will be followed up with an alternate approach to thread the desired information into TargetInfo. llvm-svn: 265806
* Basic: move CodeGenOptions from FrontendSaleem Abdulrasool2016-04-071-1/+2
| | | | | | | | This is a mechanical move of CodeGenOptions from libFrontend to libBasic. This fixes the layering violation introduced earlier by threading CodeGenOptions into TargetInfo. It should also fix the modules based self-hosting builds. NFC. llvm-svn: 265702

* Make TargetInfo store an actual DataLayout instead of a string.James Y Knight2016-03-041-6/+6
| | | | | | | | | | | | | | Use it to calculate UserLabelPrefix, instead of specifying it (often incorrectly). Note that the *actual* user label prefix has always come from the DataLayout, and is handled within LLVM. The main thing clang's TargetInfo::UserLabelPrefix did was to set the #define value. Having these be different from each-other is just silly. Differential Revision: http://reviews.llvm.org/D17183 llvm-svn: 262737

* Module Debugging: Use a nonzero DWO id for precompiled headers.Adrian Prantl2016-01-221-1/+5
| | | | | | | | | | | | | PCH files don't have a module signature and LLVM uses a nonzero DWO id as an indicator for skeleton / module CUs. This change pins the DWO id for PCH files to a known constant value. The correct long-term solution here is to implement a module signature that is an actual dterministic hash (at the moment module signatures are just random nonzero numbers) and then enable this for PCH files as well. <rdar://problem/24290667> llvm-svn: 258507
* Module Debugging: Make sure that anonymous tag decls that define globalAdrian Prantl2016-01-191-7/+6

* Module Debugging: Defer the emission of anonymous tag declsAdrian Prantl2016-01-191-0/+4
| | | | | | | | | | | | | until we are visiting their declcontext. This fixes a regression introduced in r256962: When building debug info for a typdef'd anonymous tag type, we would be visiting the inner anonymous type first thus creating a "typedef changes linkage of anonymous type, but linkage was already computed" error. rdar://problem/24199640 llvm-svn: 258152
* Module debugging: Defer emitting tag types until their definitionAdrian Prantl2016-01-061-3/+16

| | | | | | | | | | | when building a module. Clang already records the module signature when building a skeleton CU to reference a clang module. Matching the id in the skeleton with the one in the module allows a DWARF consumer to verify that they found the correct version of the module without them needing to know about the clang module format. llvm-svn: 248345
