Raw Normal View History

DebugInfo: don't use location lists when the location covers the whole function anyway Fix up three tests - one that was relying on abbreviation number, another relying on a location list in this case (& testing raw asm, changed that to use dwarfdump on the debug_info now that that's where the location is), and another which was added in r184368 - exposing a bug in that fix that is exposed when we emit the location inline rather than through a location list. Fix that bug while I'm here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184387 91177308-0d34-0410-b5e6-96231b3b80d8

Add a DIELoc class to cover the DW_FORM_exprloc set of expressions alongside DIEBlock and replace uses accordingly. Use DW_FORM_exprloc in DWARF4 and later code. Update testcases. Adding a DIELoc instead of using extra forms inside DIEBlock so that we can keep location expressions separate from other uses. No direct use at the moment, however, it's not a lot of code and using a separately named class keeps it somewhat more obvious what's going on in various locations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201481 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176671 91177308-0d34-0410-b5e6-96231b3b80d8

Debug Info: add an identifier field to DICompositeType. DICompositeType will have an identifier field at position 14. For now, the field is set to null in DIBuilder. For DICompositeTypes where the template argument field (the 13th field) was optional, modify DIBuilder to make sure the template argument field is set. Now DICompositeType has 15 fields. Update DIBuilder to use NULL instead of "i32 0" for null value of a MDNode. Update verifier to check that DICompositeType has 15 fields and the last field is null or a MDString.

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

Debug Info Verifier: enable verification of DICompileUnit. We used to call Verify before adding DICompileUnit to the list, and now we remove the check and always add DICompileUnit to the list in DebugInfoFinder, so we can verify them later on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187237 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195504 91177308-0d34-0410-b5e6-96231b3b80d8
