Use the somewhat semantic term "split dwarf" it more matches what's going on and makes a lot of the terminology in comments make more sense. llvm-svn: 169758

Now that llvm-dwarfdump supports flags to specify which DWARF section to dump, use them in tests that run llvm-dwarfdump. This is in order to make tests as specific as possible. llvm-svn: 173498

Add some first skeleton work for the DWARF5 Fission proposal. Emit part of the compile unit CU and start separating out information into the various sections that will be pulled out later. WIP. llvm-svn: 169061

Adding DIImportedModules to DIScopes. This is just the basic groundwork for supporting DW_TAG_imported_module but I wanted to commit this before pushing support further into Clang or LLVM so that this rather churny change is isolated from the rest of the work. The major churn here is obviously adding another field (within the common DIScope prefix) to all DIScopes (files, classes, namespaces, lexical scopes, etc). This should be the last big churny change needed for DW_TAG_imported_module/using directive support/PR14606. llvm-svn: 178099

Remove the (apparently) unnecessary debug info metadata indirection. The main lists of debug info metadata attached to the compile_unit had an extra layer of metadata nodes they went through for no apparent reason. This patch removes that (& still passes just as much of the GDB 7.5 test suite). If anyone can show evidence as to why these extra metadata nodes are there I'm open to reverting this patch & documenting why they're there. llvm-svn: 174266

Upgrading debug info test cases to be (more) compatible with the current debug info format. These cases were found by further work to remove support for debug info versioning. Common cleanups (other than changing the version info in the tag field) included adding the last parameter to compile_units (recently added for fission support) and other cases of trailing fields in lexical blocks, compile units, and subprograms. llvm-svn: 176834

Split out filename & directory from DIFile to start generalizing over DIScopes This is the first step to making all DIScopes have a common metadata prefix (so that things (using directives, for example) that can appear in any scope can be added to that common prefix). DIFile is itself a DIScope so the common prefix of all DIScopes cannot be a DIFile - instead it's the raw filename/directory name pair. llvm-svn: 177239

Extend the dumping infrastructure to deal with additional sections for debug info. These are some of the dwo sections from the DWARF5 split debug info proposal. Update the fission-cu.ll testcase to show what we should be able to dump more of now.

Refactor out the abbreviation handling into a separate class that controls each of the abbreviation sets (only a single one at the moment) and computes offsets separately as well for each set of DIEs.
