* [CGDebugInfo] Set the size and align for reference typesKeno Fischer2015-11-161-6/+7
| | | | | | | | | | In r253186, I changed the DIBuilder API to now take size and align for reference types as well. This was done in preparation for upcoming changes to the Verifier that will validate that sizes match between DI types and IR values that are declared as having those types. This updates clang to actually pass the information through. llvm-svn: 253190

* Stop back-patching 'readonly' Objective-C properties with 'readwrite' ones.Douglas Gregor2015-11-031-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | A 'readonly' Objective-C property declared in the primary class can effectively be shadowed by a 'readwrite' property declared within an extension of that class, so long as the types and attributes of the two property declarations are compatible. Previously, this functionality was implemented by back-patching the original 'readonly' property to make it 'readwrite', destroying source information and causing some hideously redundant, incorrect code. Simplify the implementation to express how this should actually be modeled: as a separate property declaration in the extension that shadows (via the name lookup rules) the declaration in the primary class. While here, correct some broken Fix-Its, eliminate a pile of redundant code, clean up the ARC migrator's handling of properties declared in extensions, and fix debug info's naming of methods that come from categories. A wonderous side effect of doing this write is that it eliminates the "AddedObjCPropertyInClassExtension" method from the AST mutation listener, which in turn eliminates the last place where we rewrite entire declarations in a chained PCH file or a module file. This change (which fixes rdar://problem/18475765) will allow us to eliminate the rewritten-decls logic from the serialization library, and fixes a crash (rdar://problem/23247794) illustrated by the test/PCH/chain-categories.m example. llvm-svn: 251874

* Support Debug Info path remappingSaleem Abdulrasool2015-10-121-8/+20
| | | | | | | | | | | | | | | | Add support for the `-fdebug-prefix-map=` option as in GCC. The syntax is `-fdebug-prefix-map=OLD=NEW`. When compiling files from a path beginning with OLD, change the debug info to indicate the path as start with NEW. This is particularly helpful if you are preprocessing in one path and compiling in another (e.g. for a build cluster with distcc). Note that the linearity of the implementation is not as terrible as it may seem. This is normally done once per file with an expectation that the map will be small (1-2) entries, making this roughly linear in the number of input paths. Addresses PR24619. llvm-svn: 250094

* Module Debugging: Use the clang module signature as the module's dwo_idAdrian Prantl2015-09-221-0/+6
| | | | | | | | | | | 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

| | | | | | | | | | | The signature may not have been computed at the time the module reference is generated (e.g.: in the future while emitting debug info for a clang module). Using the full module name is safe because each clang module may only have a single definition. NFC. llvm-svn: 248037

* CGDebugInfo: Factor out a getOrCreateStandaloneType() method.Adrian Prantl2015-08-271-3/+15
| | | | | | | | | | | Usually debug info is created on the fly while during codegen. With this API it becomes possible to create standalone debug info for types that are not referenced by any code, such as emitting debug info for a clang module or for implementing something like -gfull. Because on-the-fly debug info generation may still insert retained types on top of them, all RetainedTypes are uniqued in CGDebugInfo::finalize(). llvm-svn: 246210
* Add a -gmodules option to the driver and a -dwarf-ext-refs to cc1Adrian Prantl2015-08-271-0/+1
| | | | | | | | | | | | | to enable the use of external type references in the debug info (a.k.a. module debugging). The driver expands -gmodules to "-g -fmodule-format=obj -dwarf-ext-refs" and passes that to cc1. All this does at the moment is set a flag codegenopts. http://reviews.llvm.org/D11958 llvm-svn: 246192

* DI: Make getOrCreateLimitedType() return DICompositeType, NFCDuncan P. N. Exon Smith2015-07-241-6/+4
| | | | | | | | | Change `getOrCreateLimitedType()` to return a `DICompositeType` and remove the casts from its callers. Inside, I've strengthened a `cast` from `DICompositeTypeBase`, but the casts in the callers already prove that this is safe. There should be no functionality change here. llvm-svn: 243155
