[AIX][ZOS] Disable LIT tests on AIX and z/OS due to lack of Objective-C support AIX and z/OS lack Objective-C support, so mark these tests as unsupported for AIX and z/OS. Reviewed By: jsji Differential Revision: https://reviews.llvm.org/D109060

[modules][debuginfo] Only include imported modules when targeting LLDB These constructs are only applicable to a debugger capable of loading a Clang AST, so omit them for brevity when not doing so. We could potentially propagate more of CodeGenOptions through the ObjectFilePCGContainerOperations for consistency (so the next person who adds some CodeGenOpts feature that tweaks debug info output doesn't get caught by this), so I'm open to objections/alternatives there, but went with this for now. Tested just a couple of basic cases (one direct, one indirect (through the ObjectFilePCHContainerOperations) & fixed up other cases to pass the -debugger-tuning flag as appropriate. llvm-svn: 268460

// CHECK: ![[CU:.*]] = distinct !DICompileUnit
Move the sysroot attribute from DIModule to DICompileUnit [this re-applies c0176916a4824812d25a5a22c4ff7c95857b0cd6 with the correct commit message and phabricator link] This addresses point 1 of PR44213. https://bugs.llvm.org/show_bug.cgi?id=44213 The DW_AT_LLVM_sysroot attribute is used for Clang module debug info, to allow LLDB to import a Clang module from source. Currently it is part of each DW_TAG_module, however, it is the same for all modules in a compile unit. It is more efficient and less ambiguous to store it once in the DW_TAG_compile_unit. This should have no effect on DWARF consumers other than LLDB. Differential Revision: https://reviews.llvm.org/D71732

Module Debugging: Emit debug type information into clang ObjC modules. When -fmodule-format is set to "obj", emit debug info for all types declared in a module or referenced by a declaration into the module's object file container. This patch adds support for Objective-C types and methods. llvm-svn: 247068

// SKEL-CHECK: includePath: "/SRCDIR/Inputs"
Correctly initialize the DW_AT_comp_dir attribute of Clang module skeleton CUs Before this patch a Clang module skeleton CU would have a DW_AT_comp_dir pointing to the directory of the module map file, and this information was not used by anyone. Even worse, LLDB actually resolves relative DWO paths by appending it to DW_AT_comp_dir. This patch sets it to the same directory that is used as the main CU's compilation directory, which would make the LLDB code work. Differential Revision: https://reviews.llvm.org/D76377
