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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169758 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173498 91177308-0d34-0410-b5e6-96231b3b80d8

DW_FORM_sec_offset should be a relocation on platforms that use a relocation across sections. Do this for DW_AT_stmt list in the skeleton CU and check the relocations in the debug_info section. Add a FIXME for multiple CUs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178969 91177308-0d34-0410-b5e6-96231b3b80d8

Revert "Revert "PR14606: debug info imported_module support"" This reverts commit r179840 with a fix to test/DebugInfo/two-cus-from-same-file.ll I'm not sure why that test only failed on ARM & MIPS and not X86 Linux, even though the debug info was clearly invalid on all of them, but this ought to fix it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179996 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174266 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176834 91177308-0d34-0410-b5e6-96231b3b80d8

Revert "Adding DIImportedModules to DIScopes." This reverts commit 342d92c7a0adeabc9ab00f3f0d88d739fe7da4c7. Turns out we're going with a different schema design to represent DW_TAG_imported_modules so we won't need this extra field. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178215 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177239 91177308-0d34-0410-b5e6-96231b3b80d8

Sneak in two other small changes: a) Print out the debug_str_offsets.dwo section. b) Change form we're expecting the entries in the debug_str_offsets.dwo section to take from ULEB128 to U32. Add tests for all of this in the fission-cu.ll test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172578 91177308-0d34-0410-b5e6-96231b3b80d8

The .dwo section shouldn't contain the unrelocated values (and therefore not at all) of the pc or statement list. We also don't need to emit the compilation dir so save so space and time and don't bother. Fix up the testcase accordingly and verify that we don't emit the attributes or the items that they use. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179114 91177308-0d34-0410-b5e6-96231b3b80d8

Split address information for DWARF5 split dwarf proposal. This involves using the DW_FORM_GNU_addr_index and a separate .debug_addr section which stays in the executable and is fully linked.

DW_FORM_sec_offset should be a relocation on platforms that use a relocation across sections. Do this for DW_AT_stmt list in the skeleton CU and check the relocations in the debug_info section. Add a FIXME for multiple CUs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178969 91177308-0d34-0410-b5e6-96231b3b80d8
