2013-03-28Revert "Adding DIImportedModules to DIScopes."David Blaikie
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
2013-03-27Adding DIImportedModules to DIScopes.David Blaikie
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178099 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-22Remove the ARM-specific variant of this test. It's already covered byChandler Carruth
the ARM build bots, and it adds a weird case to the test suite where a test uses as inputs files in the parent directory.

2013-03-20Refactor the DIFile (2nd) parameter to DITypes to be an MDNode reference to ↵David Blaikie
a raw directory/file pair This makes DIType's first non-tag parameter the same as DIFile's, allowing them to both share the common implementation of getFilename/getDirectory in DIScope. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177467 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-19Move the DIFile operand to DITypes from the 4th operand to the 2nd.David Blaikie
This is another step along the way to making all DIScopes have a common prefix which can be added to in a general manner to support using directives (DW_TAG_imported_module). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177462 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-17Split out filename & directory from DIFile to start generalizing over DIScopesDavid Blaikie
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

2013-03-13Refactor filename/directory in DICompileUnit into a DIFileDavid Blaikie

2013-03-12Update debug info test cases with empty SplitDebugFilename field.David Blaikie
This could be 'null' or the empty string, DIDescriptor::getStringField coalesces the two cases anyway so it's just a matter of legible/efficient representation. The change in behavior of the DICompileUnit::get* functions could be subsumed by the full verification check - but ideally that should just be an assertion if we could front-load the actual debug info metadata failure paths. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176907 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-11Upgrading debug info test cases to be (more) compatible with the current ↵David Blaikie
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
2013-03-08Remove -print-dbginfo as it is unused & bitrotten.David Blaikie
This pass hasn't been touched in two years & would fail with assertions against the current debug info metadata format (the only test case for it still uses a many-versions old debug info metadata format) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176707 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-08Upgrade tests to the latest debug info format.David Blaikie
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
2013-03-07Debug Info: store the files and directories for each compile unit.Manman Ren
We now emit a line table for each compile unit. To reduce the prologue size of each line table, the files and directories used by each compile unit are stored in std::map<unsigned, std::vector< > > instead of std::vector< >. The prologue for a lto'ed image can be as big as 93K. Duplicating 93K for each compile unit causes a huge increase of debug info. With this patch, each prologue will only emit the files required by the compile unit. rdar://problem/13342023 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176605 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-21Previously, parsing capability of the .debug_frame section was addedEli Bendersky
to lib/DebugInfo, with dumping in llvm-dwarfdump. This patch adds initial ability to parse and dump CFA instructions contained in entries. To keep it manageable, the patch omits some more advanced capabilities (accounted in TODOs): * Parsing of instructions with BLOCK arguments (expression lists) * Dumping of actual instruction arguments (currently only names are dumped). This is quite tricky since the dumper has to effectively "interpret" the instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175820 91177308-0d34-0410-b5e6-96231b3b80d8
