| | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@265806 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | This threads CodeGenOptions into the TargetInfo hierarchy. This is motivated by ARM which can change some target information based on the EABI selected (-meabi).

* Introduce module file extensions to piggy-back data onto module files.Douglas Gregor2015-11-031-1/+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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@251955 91177308-0d34-0410-b5e6-96231b3b80d8

* Make the clang module container format selectable from the command line.Adrian Prantl2015-07-171-1/+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.

* Introduce a PCHContainerOperations interface (NFC).Adrian Prantl2015-06-201-9/+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 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@240225 91177308-0d34-0410-b5e6-96231b3b80d8

* [modules] Deserialize CXXCtorInitializer list for a constructor lazily.Richard Smith2015-03-241-0/+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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@233052 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | This is a necessary prerequisite for debugging with modules.
