| | | | | | | | | for constructors and destructors since the original declaration given by the AT_specification both won't and can't. Patch by Yacine Belkadi, I've cleaned up the testcases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181471 91177308-0d34-0410-b5e6-96231b3b80d8
* Debug Info: Support DW_TAG_imported_declarationDavid Blaikie2013-05-08
| | | | | | | | | | | | | | This provides basic functionality for imported declarations. For subprograms and types some amount of lazy construction is supported (so the definition of a function can proceed the using declaration), but it still doesn't handle declared-but-not-defined functions (since we don't generally emit function declarations). Variable support is really rudimentary at the moment - simply looking up the existing definition with no support for out of order (declaration, imported_module, then definition). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181392 91177308-0d34-0410-b5e6-96231b3b80d8
* Debug Info: Fix for break due to r181271David Blaikie2013-05-07
| | | | | | | | | Apparently we didn't keep an association of Compile Unit metadata nodes to DIEs so looking up that parental context failed & thus caused no DW_TAG_imported_modules to be emitted at the CU scope. Fix this by adding the mapping & sure up the test case to verify this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181339 91177308-0d34-0410-b5e6-96231b3b80d8

* [SystemZ] Update non-pic DWARF encodingsUlrich Weigand2013-05-06
| | | | | | | | | | | | | | As pointed out by Rafael Espindola, we should match the DWARF encodings produced by GCC in both pic and non-pic modes. This was not the case for the non-pic case. This patch changes all DWARF encodings to DW_EH_PE_absptr for the non-pic case, just like GCC does. The test case is updated to check for both variants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181222 91177308-0d34-0410-b5e6-96231b3b80d8

* Use the target triple from the target machine rather than the moduleEric Christopher2013-04-27
| | | | | | | | | | | | | | | | to determine whether or not we're on a darwin platform for debug code emitting. Solves the problem of a module with no triple on the command line and no triple in the module using non-gdb ok features on darwin. Fix up the member-pointers test to check the correct things for cross platform (DW_FORM_flag is a good prefix). Unfortunately no testcase because I have no ideas how to test something without a triple and without a triple in the module yet check precisely on two platforms. Ideas welcome. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180660 91177308-0d34-0410-b5e6-96231b3b80d8

* Bugfix for the debug intrinsic handling in InstCombiner:Adrian Prantl2013-04-26
| | | | | | | | | | | Since we can't guarantee that the original dbg.declare instrinsic is removed by LowerDbgDeclare(), we need to make sure that we are not inserting the same dbg.value intrinsic over and over.

* Adding DIImportedModules to DIScopes.David Blaikie2013-03-27
| | | | | | | | | | | | 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
