DebugInfo: Remove some unneeded conditionals now that DIBuilder no longer emits zero-length arrays as {i32 0} A bunch of test cases needed to be cleaned up for this, many my fault - when implementid imported modules I updated test cases by simply duplicating the prior metadata field - which wasn't always the empty metadata entry. llvm-svn: 200731

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

DebugInfo: Sure up subprogram variable list handling with more assertions and fewer conditionals. Many old tests using prior schemas still had some brokenness here (both indirect arrays and arrays with single bogus elements). Fixed those up so they don't hit the new assertions. Also reduced nesting in some places, etc. llvm-svn: 208817

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. llvm-svn: 178215

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

Debug Info: instead of calling addToContextOwner which constructs the context after the DIE creation, we construct the context first. This touches creation of namespaces and global variables. The purpose is to handle all DIE creations similarly: constructs the context first, then creates the DIE and immediately adds the DIE to its parent. We use createAndAddDIE to wrap around "new DIE(". llvm-svn: 193589

DebugInfo: Refactor some tests to allow DW_AT_name to not be the first attribute in a local variable. In an effort to fix concrete variables referencing abstract origins where the concrete variable preceeds the first inlined usage, the addition of attributes such as name, file, etc will be delayed until the end of the module (to wait to see if any inlined instances have occurred, thus necessitating an abstract definition that the concrete definition should also reference). These test cases don't actually need to care about this ordering of attributes, so update them to be more resilient to such changes coming in the near future. llvm-svn: 210940
