Debug info: Remove ARMAsmPrinter::EmitDwarfRegOp(). AsmPrinter can now scan the register file for sub- and super-registers. No functionality change intended. (Tests are updated because the comments in the assembler output are different.) llvm-svn: 202416

Debug Info: update testing cases to specify the debug info version number. We are going to drop debug info without a version number or with a different version number, to make sure we don't crash when we see bitcode files with different debug info metadata format. llvm-svn: 195504

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

Upgrade tests to the latest debug info format. Mostly this is just changing the named metadata (llvm.dbg.sp, llvm.dbg.gv, llvm.dbg.<func>.lv, etc -> llvm.dbg.cu), adding a few fields to older records (DIVariable: flags/inlined-at, DICompileUnit: sp/gv/types, DISubprogram: local variables list) The tests to update were discovered by a change I'm working on to remove debug info version support - so any tests using old debug info versions I haven't updated probably are bad tests or just not actually designed to test debug info. llvm-svn: 176671

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
